If you want + to match `/foo/` you have to add a route specifically for that ([#1086]) + + For example: + + ```rust + use axum::{Router, routing::get, extract::Path}; + + let app = Router::new() + // this will match `/foo/bar/baz` + .route("/foo/*rest", get(handler)) + // this will match `/foo/` + .route("/foo/", get(handler)) + // if you want `/foo` to match you must also add an explicit route for it + .route("/foo", get(handler)); + + async fn handler( + // use an `Option` because `/foo/` and `/foo` don't have any path params + params: Option>, + ) {} + ``` + +- **breaking:** Path params for wildcard routes no longer include the prefix + `/`. e.g. `/foo.js` will match `/*filepath` with a value of `foo.js`, _not_ + `/foo.js` ([#1086]) + + For example: + + ```rust + use axum::{Router, routing::get, extract::Path}; + + let app = Router::new().route("/foo/*rest", get(handler)); + + async fn handler( + Path(params): Path, + ) { + // for the request `/foo/bar/baz` the value of `params` will be `bar/baz` + // + // on 0.5 it would be `/bar/baz` + } + ``` + +- **fixed:** Routes like `/foo` and `/*rest` are no longer considered + overlapping. `/foo` will take priority ([#1086]) + + For example: + + ```rust + use axum::{Router, routing::get}; + + let app = Router::new() + // this used to not be allowed but now just works + .route("/foo/*rest", get(foo)) + .route("/foo/bar", get(bar)); + + async fn foo() {} + + async fn bar() {} + ``` + +- **breaking:** Trailing slash redirects have been removed. Previously if you + added a route for `/foo`, axum would redirect calls to `/foo/` to `/foo` (or + vice versa for `/foo/`). That is no longer supported and such requests will + now be sent to the fallback. Consider using + `axum_extra::routing::RouterExt::route_with_tsr` if you want the old behavior + ([#1119]) + + For example: + + ```rust + use axum::{Router, routing::get}; + + let app = Router::new() + // a request to `GET /foo/` will now get `404 Not Found` + // whereas in 0.5 axum would redirect to `/foo` + // + // same goes the other way if you had the route `/foo/` + // axum will no longer redirect from `/foo` to `/foo/` + .route("/foo", get(handler)); + + async fn handler() {} + ``` + +- **breaking:** `Router::fallback` now only accepts `Handler`s (similarly to + what `get`, `post`, etc accept). Use the new `Router::fallback_service` for + setting any `Service` as the fallback ([#1155]) + + This fallback on 0.5: + + ```rust + use axum::{Router, handler::Handler}; + + let app = Router::new().fallback(fallback.into_service()); + + async fn fallback() {} + ``` + + Becomes this in 0.6 + + ```rust + use axum::Router; + + let app = Router::new().fallback(fallback); + + async fn fallback() {} + ``` + +- **breaking:** Allow `Error: Into` for `Route::{layer, route_layer}` ([#924]) +- **breaking:** `MethodRouter` now panics on overlapping routes ([#1102]) +- **breaking:** `Router::route` now only accepts `MethodRouter`s created with + `get`, `post`, etc. Use the new `Router::route_service` for routing to + any `Service`s ([#1155]) + +## Extractors + +- **added:** Added new type safe `State` extractor. This can be used with + `Router::with_state` and gives compile errors for missing states, whereas + `Extension` would result in runtime errors ([#1155]) + + We recommend migrating from `Extension` to `State` since that is more type + safe and faster. That is done by using `Router::with_state` and `State`. + + This setup in 0.5 + + ```rust + use axum::{routing::get, Extension, Router}; + + let app = Router::new() + .route("/", get(handler)) + .layer(Extension(AppState {})); + + async fn handler(Extension(app_state): Extension) {} + + #[derive(Clone)] + struct AppState {} + ``` + + Becomes this in 0.6 using `State`: + + ```rust + use axum::{routing::get, extract::State, Router}; + + let app = Router::with_state(AppState {}) + .route("/", get(handler)); + + async fn handler(State(app_state): State) {} + + #[derive(Clone)] + struct AppState {} + ``` + + If you have multiple extensions you can use fields on `AppState` and implement + `FromRef`: + + ```rust + use axum::{extract::{State, FromRef}, routing::get, Router}; + + let state = AppState { + client: HttpClient {}, + database: Database {}, + }; + + let app = Router::with_state(state).route("/", get(handler)); + + async fn handler( + State(client): State, + State(database): State, + ) {} + + #[derive(Clone)] + struct AppState { + client: HttpClient, + database: Database, + } + + #[derive(Clone)] + struct HttpClient {} + + impl FromRef for HttpClient { + fn from_ref(state: &AppState) -> Self { + state.client.clone() + } + } + + #[derive(Clone)] + struct Database {} + + impl FromRef for Database { + fn from_ref(state: &AppState) -> Self { + state.database.clone() + } + } + ``` +- **breaking:** It is now only possible for one extractor per handler to consume + the request body. In 0.5 doing so would result in runtime errors but in 0.6 it + is a compile error ([#1272]) + + axum enforces this by only allowing the _last_ extractor to consume the + request. + + For example: + + ```rust + use axum::{Json, http::HeaderMap}; + + // This wont compile on 0.6 because both `Json` and `String` need to consume + // the request body. You can use either `Json` or `String`, but not both. + async fn handler_1( + json: Json, + string: String, + ) {} + + // This won't work either since `Json` is not the last extractor. + async fn handler_2( + json: Json, + headers: HeaderMap, + ) {} + + // This works! + async fn handler_3( + headers: HeaderMap, + json: Json, + ) {} + ``` + + This is done by reworking the `FromRequest` trait and introducing a new + `FromRequestParts` trait. + + If your extractor needs to consume the request body then you should implement + `FromRequest`, otherwise implement `FromRequestParts`. + + This extractor in 0.5: + + ```rust + struct MyExtractor { /* ... */ } + + #[async_trait] + impl FromRequest for MyExtractor + where + B: Send, + { + type Rejection = StatusCode; + + async fn from_request(req: &mut RequestParts) -> Result { + // ... + } + } + ``` + + Becomes this in 0.6: + + ```rust + use axum::{ + extract::{FromRequest, FromRequestParts}, + http::{StatusCode, Request, request::Parts}, + async_trait, + }; + + struct MyExtractor { /* ... */ } + + // implement `FromRequestParts` if you don't need to consume the request body + #[async_trait] + impl FromRequestParts for MyExtractor + where + S: Send + Sync, + { + type Rejection = StatusCode; + + async fn from_request_parts(parts: &mut Parts, state: &S) -> Result { + // ... + } + } + + // implement `FromRequest` if you do need to consume the request body + #[async_trait] + impl FromRequest for MyExtractor + where + S: Send + Sync, + B: Send + 'static, + { + type Rejection = StatusCode; + + async fn from_request(req: Request, state: &S) -> Result { + // ... + } + } + ``` + +- **breaking:** `RequestParts` has been removed as part of the `FromRequest` + rework ([#1272]) +- **breaking:** `BodyAlreadyExtracted` has been removed ([#1272]) +- **breaking:** The following types or traits have a new `S` type param + which represents the state ([#1155]): + - `Router`, defaults to `()` + - `MethodRouter`, defaults to `()` + - `FromRequest`, no default + - `Handler`, no default +- **added:** Add `RequestExt` and `RequestPartsExt` which adds convenience + methods for running extractors to `http::Request` and `http::request::Parts` ([#1301]) + +## Middleware + +- **breaking:** Remove `extractor_middleware` which was previously deprecated. + Use `axum::middleware::from_extractor` instead ([#1077]) +- **added:** Support running extractors on `middleware::from_fn` functions ([#1088]) +- **added:** Support any middleware response that implements `IntoResponse` ([#1152]) +- **breaking:** Require middleware added with `Handler::layer` to have + `Infallible` as the error type ([#1152]) + +## Misc + +- **changed:** axum's MSRV is now 1.60 ([#1239]) +- **changed:** For methods that accept some `S: Service`, the bounds have been + relaxed so the response type must implement `IntoResponse` rather than being a + literal `Response` +- **fixed:** Annotate panicking functions with `#[track_caller]` so the error + message points to where the user added the invalid route, rather than + somewhere internally in axum ([#1248]) +- **added:** Add `ServiceExt` with methods for turning any `Service` into a + `MakeService` similarly to `Router::into_make_service` ([#1302]) + +[#1077]: https://github.com/tokio-rs/axum/pull/1077 +[#1086]: https://github.com/tokio-rs/axum/pull/1086 +[#1088]: https://github.com/tokio-rs/axum/pull/1088 +[#1102]: https://github.com/tokio-rs/axum/pull/1102 +[#1119]: https://github.com/tokio-rs/axum/pull/1119 +[#1152]: https://github.com/tokio-rs/axum/pull/1152 +[#1155]: https://github.com/tokio-rs/axum/pull/1155 +[#1239]: https://github.com/tokio-rs/axum/pull/1239 +[#1248]: https://github.com/tokio-rs/axum/pull/1248 +[#1272]: https://github.com/tokio-rs/axum/pull/1272 +[#1301]: https://github.com/tokio-rs/axum/pull/1301 +[#1302]: https://github.com/tokio-rs/axum/pull/1302 +[#924]: https://github.com/tokio-rs/axum/pull/924 + +

([#286]) + - **breaking:** `Route::boxed` and `BoxRoute` have been removed as they're no longer + necessary ([#404]) + - **breaking:** `Nested`, `Or` types are now private.

So `.route("/", get(get_handler).post(post_handler))` and + _not_ `.route("/", get(get_handler)).route("/", post(post_handler))`. + - **fixed:** Correctly handle trailing slashes in routes: + - If a route with a trailing slash exists and a request without a trailing + slash is received, axum will send a 301 redirection to the route with the + trailing slash. + - Or vice versa if a route without a trailing slash exists and a request + with a trailing slash is received. + - This can be overridden by explicitly defining two routes: One with and one + without a trailing slash. + - **breaking:** Method routing for handlers has been moved from `axum::handler` + to `axum::routing`. So `axum::handler::get` now lives at `axum::routing::get` + ([#405]) + - **breaking:** Method routing for services has been moved from `axum::service` + to `axum::routing::service_method_routing`. So `axum::service::get` now lives at + `axum::routing::service_method_routing::get`, etc. ([#405]) + - **breaking:** `Router::or` renamed to `Router::merge` and will now panic on + overlapping routes. It now only accepts `Router`s and not general `Service`s. + Use `Router::fallback` for adding fallback routes ([#408]) + - **added:** `Router::fallback` for adding handlers for request that didn't + match any routes. `Router::fallback` must be use instead of `nest("/", _)` ([#408]) + - **breaking:** `EmptyRouter` has been renamed to `MethodNotAllowed` as it's only + used in method routers and not in path routers (`Router`) + - **breaking:** Remove support for routing based on the `CONNECT` method.

So `axum`'s performance is comparable to [`hyper`]. You can find +benchmarks [here](https://github.com/programatik29/rust-web-benchmarks) and +[here](https://web-frameworks-benchmark.netlify.app/result?l=rust). + +## Safety + +This crate uses `#![forbid(unsafe_code)]` to ensure everything is implemented in +100% safe Rust. + +## Minimum supported Rust version + +axum's MSRV is 1.63. + +## Examples + +The [examples] folder contains various examples of how to use `axum`. The +[docs] also provide lots of code snippets and examples.

Thus axum requires those errors to be handled gracefully: + +```rust +use axum::{ + routing::get, + error_handling::HandleErrorLayer, + http::StatusCode, + BoxError, + Router, +}; +use tower::{ServiceBuilder, timeout::TimeoutLayer}; +use std::time::Duration; + +async fn handler() {} + +let app = Router::new() + .route("/", get(handler)) + .layer( + ServiceBuilder::new() + // this middleware goes above `TimeoutLayer` because it will receive + // errors returned by `TimeoutLayer` + .layer(HandleErrorLayer::new(|_: BoxError| async { + StatusCode::REQUEST_TIMEOUT + })) + .layer(TimeoutLayer::new(Duration::from_secs(10))) + ); +# async { +# axum::Server::bind(&"".parse().unwrap()).serve(app.into_make_service()).await.unwrap(); +# }; +``` + +See [`error_handling`](crate::error_handling) for more details on axum's error +handling model. + +# Routing to services/middleware and backpressure + +Generally routing to one of multiple services and backpressure doesn't mix +well. Ideally you would want ensure a service is ready to receive a request +before calling it. However, in order to know which service to call, you need +the request... + +One approach is to not consider the router service itself ready until all +destination services are ready. That is the approach used by +[`tower::steer::Steer`]. + +Another approach is to always consider all services ready (always return +`Poll::Ready(Ok(()))`) from `Service::poll_ready` and then actually drive +readiness inside the response future returned by `Service::call`. This works +well when your services don't care about backpressure and are always ready +anyway. + +axum expects that all services used in your app wont care about +backpressure and so it uses the latter strategy. However that means you +should avoid routing to a service (or using a middleware) that _does_ care +about backpressure. At the very least you should [load shed] so requests are +dropped quickly and don't keep piling up. + +It also means that if `poll_ready` returns an error then that error will be +returned in the response future from `call` and _not_ from `poll_ready`. In +that case, the underlying service will _not_ be discarded and will continue +to be used for future requests. Services that expect to be discarded if +`poll_ready` fails should _not_ be used with axum. + +One possible approach is to only apply backpressure sensitive middleware +around your entire app. This is possible because axum applications are +themselves services: + +```rust +use axum::{ + routing::get, + Router, +}; +use tower::ServiceBuilder; +# let some_backpressure_sensitive_middleware = +# tower::layer::util::Identity::new(); + +async fn handler() { /* ... */ } + +let app = Router::new().route("/", get(handler)); + +let app = ServiceBuilder::new() + .layer(some_backpressure_sensitive_middleware) + .service(app); +# async { +# axum::Server::bind(&"".parse().unwrap()).serve(app.into_make_service()).await.unwrap(); +# }; +``` + +However when applying middleware around your whole application in this way +you have to take care that errors are still being handled with +appropriately. + +Also note that handlers created from async functions don't care about +backpressure and are always ready.

See [`response`](crate::response) for more details on building responses. +//! +//! # Error handling +//! +//! axum aims to have a simple and predictable error handling model. That means +//! it is simple to convert errors into responses and you are guaranteed that +//! all errors are handled. +//! +//! See [`error_handling`](crate::error_handling) for more details on axum's +//! error handling model and how to handle errors gracefully. +//! +//! # Middleware +//! +//! There are several different ways to write middleware for axum. See +//! [`middleware`](crate::middleware) for more details. +//! +//! # Sharing state with handlers +//! +//! It is common to share some state between handlers. For example, a +//! pool of database connections or clients to other services may need to +//! be shared. +//! +//! The three most common ways of doing that are: +//! - Using the [`State`] extractor +//! - Using request extensions +//! - Using closure captures +//! +//! ## Using the [`State`] extractor +//! +//! ```rust,no_run +//! use axum::{ +//! extract::State, +//! routing::get, +//! Router, +//! }; +//! use std::sync::Arc; +//! +//! struct AppState { +//! // ... +//! } +//! +//! let shared_state = Arc::new(AppState { /* ... */ }); +//! +//! let app = Router::new() +//! .route("/", get(handler)) +//! .with_state(shared_state); +//! +//! async fn handler( +//! State(state): State>, +//! ) { +//! // ... +//! } +//! # async { +//! # axum::Server::bind(&"".parse().unwrap()).serve(app.into_make_service()).await.unwrap(); +//! # }; +//! ``` +//! +//! You should prefer using [`State`] if possible since it's more type safe. The downside is that +//! it's less dynamic than request extensions. +//! +//! See [`State`] for more details about accessing state. +//! +//! ## Using request extensions +//! +//! Another way to extract state in handlers is using [`Extension`](crate::extract::Extension) as +//! layer and extractor: +//! +//! ```rust,no_run +//! use axum::{ +//! extract::Extension, +//! routing::get, +//! Router, +//! }; +//! use std::sync::Arc; +//! +//! struct AppState { +//! // ... +//! } +//! +//! let shared_state = Arc::new(AppState { /* ... */ }); +//! +//! let app = Router::new() +//! .route("/", get(handler)) +//! .layer(Extension(shared_state)); +//! +//! async fn handler( +//! Extension(state): Extension>, +//! ) { +//! // ... +//! } +//! # async { +//! # axum::Server::bind(&"".parse().unwrap()).serve(app.into_make_service()).await.unwrap(); +//! # }; +//! ``` +//! +//! The downside to this approach is that you'll get runtime errors +//! (specifically a `500 Internal Server Error` response) if you try and extract +//! an extension that doesn't exist, perhaps because you forgot to add the +//! middleware or because you're extracting the wrong type. +//! +//! ## Using closure captures +//! +//! State can also be passed directly to handlers using closure captures: +//! +//! ```rust,no_run +//! use axum::{ +//! Json, +//! extract::{Extension, Path}, +//! routing::{get, post}, +//! Router, +//! }; +//! use std::sync::Arc; +//! use serde::Deserialize; +//! +//! struct AppState { +//! // ... +//! } +//! +//! let shared_state = Arc::new(AppState { /* ... */ }); +//! +//! let app = Router::new() +//! .route( +//! "/users", +//! post({ +//! let shared_state = Arc::clone(&shared_state); +//! move |body| create_user(body, shared_state) +//! }), +//! ) +//! .route( +//! "/users/:id", +//! get({ +//! let shared_state = Arc::clone(&shared_state); +//! move |path| get_user(path, shared_state) +//! }), +//! ); +//! +//! async fn get_user(Path(user_id): Path, state: Arc) { +//! // ... +//! } +//! +//! async fn create_user(Json(payload): Json, state: Arc) { +//! // ... +//! } +//! +//! #[derive(Deserialize)] +//! struct CreateUserPayload { +//! // ... +//! } +//! # async { +//! # axum::Server::bind(&"".parse().unwrap()).serve(app.into_make_service()).await.unwrap(); +//! # }; +//! ``` +//! +//! The downside to this approach is that it's a little more verbose than using +//! [`State`] or extensions. +//! +//! # Building integrations for axum +//! +//! Libraries authors that want to provide [`FromRequest`], [`FromRequestParts`], or +//! [`IntoResponse`] implementations should depend on the [`axum-core`] crate, instead of `axum` if +//! possible. [`axum-core`] contains core types and traits and is less likely to receive breaking +//! changes. +//! +//! # Required dependencies +//! +//! To use axum there are a few dependencies you have to pull in as well: +//! +//! ```toml +//! [dependencies] +//! axum = "" +//! hyper = { version = "", features = ["full"] } +//! tokio = { version = "", features = ["full"] } +//! tower = "" +//! ``` +//! +//! The `"full"` feature for hyper and tokio isn't strictly necessary but it's +//! the easiest way to get started. +//! +//! Note that [`hyper::Server`] is re-exported by axum so if that's all you need +//! then you don't have to explicitly depend on hyper. +//! +//! Tower isn't strictly necessary either but helpful for testing. See the +//! testing example in the repo to learn more about testing axum apps. +//! +//! # Examples +//! +//! The axum repo contains [a number of examples][examples] that show how to put all the +//! pieces together. +//! +//! # Feature flags +//! +//! axum uses a set of [feature flags] to reduce the amount of compiled and +//! optional dependencies. +//! +//! The following optional features are available: +//! +//! Name | Description | Default? +//! ---|---|--- +//! `headers` | Enables extracting typed headers via [`TypedHeader`] | No +//! `http1` | Enables hyper's `http1` feature | Yes +//! `http2` | Enables hyper's `http2` feature | No +//! `json` | Enables the [`Json`] type and some similar convenience functionality | Yes +//! `macros` | Enables optional utility macros | No +//! `matched-path` | Enables capturing of every request's router path and the [`MatchedPath`] extractor | Yes +//! `multipart` | Enables parsing `multipart/form-data` requests with [`Multipart`] | No +//! `original-uri` | Enables capturing of every request's original URI and the [`OriginalUri`] extractor | Yes +//! `tokio` | Enables `tokio` as a dependency and `axum::Server`, `SSE` and `extract::connect_info` types. | Yes +//! `tower-log` | Enables `tower`'s `log` feature | Yes +//! `tracing` | Log rejections from built-in extractors | No +//! `ws` | Enables WebSockets support via [`extract::ws`] | No +//! `form` | Enables the `Form` extractor | Yes +//! `query` | Enables the `Query` extractor | Yes +//! +//!

Efficient and customizable data-encoding functions like base64, base32, and hex +//! +//! This [crate] provides little-endian ASCII base-conversion encodings for +//! bases of size 2, 4, 8, 16, 32, and 64.

You may use the [binary] or the [website] to play around. +//! +//! # Examples +//! +//! This crate provides predefined encodings as [constants]. These constants are of type +//! [`Encoding`]. This type provides encoding and decoding functions with in-place or allocating +//! variants. Here is an example using the allocating encoding function of [`BASE64`]: +//! +//! ```rust +//! use data_encoding::BASE64; +//! assert_eq!(BASE64.encode(b"Hello world"), "SGVsbG8gd29ybGQ="); +//! ``` +//! +//! Here is an example using the in-place decoding function of [`BASE32`]: +//! +//! ```rust +//! use data_encoding::BASE32; +//! let input = b"JBSWY3DPEB3W64TMMQ======"; +//! let mut output = vec![0; BASE32.decode_len(input.len()).unwrap()]; +//! let len = BASE32.decode_mut(input, &mut output).unwrap(); +//! assert_eq!(&output[0 .. len], b"Hello world"); +//! ``` +//! +//! You are not limited to the predefined encodings. You may define your own encodings (with the +//! same correctness and performance properties as the predefined ones) using the [`Specification`] +//! type: +//! +//! ```rust +//! use data_encoding::Specification; +//! let hex = { +//! let mut spec = Specification::new(); +//! spec.symbols.push_str("0123456789abcdef"); +//! spec.encoding().unwrap() +//! }; +//! assert_eq!(hex.encode(b"hello"), "68656c6c6f"); +//! ``` +//! +//! You may use the [macro] library to define a compile-time custom encoding: +//! +//! ```rust,ignore +//! use data_encoding::Encoding; +//! use data_encoding_macro::new_encoding; +//! const HEX: Encoding = new_encoding!{ +//! symbols: "0123456789abcdef", +//! translate_from: "ABCDEF", +//! translate_to: "abcdef", +//! }; +//! const BASE64: Encoding = new_encoding!{ +//! symbols: "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/", +//! padding: '=', +//! }; +//! ``` +//! +//! # Properties +//! +//! The [`HEXUPPER`], [`BASE32`], [`BASE32HEX`], [`BASE64`], and [`BASE64URL`] predefined encodings +//! conform to [RFC4648]. +//! +//! In general, the encoding and decoding functions satisfy the following properties: +//! +//! - They are deterministic: their output only depends on their input +//! - They have no side-effects: they do not modify any hidden mutable state +//! - They are correct: encoding followed by decoding gives the initial data +//! - They are canonical (unless [`is_canonical`] returns false): decoding followed by encoding +//! gives the initial data +//! +//! This last property is usually not satisfied by base64 implementations. This is a matter of +//! choice and this crate has made the choice to let the user choose. Support for canonical encoding +//! as described by the [RFC][canonical] is provided. But it is also possible to disable checking +//! trailing bits, to add characters translation, to decode concatenated padded inputs, and to +//! ignore some characters. Note that non-canonical encodings may be an attack vector as described +//! in [Base64 Malleability in Practice](https://eprint.iacr.org/2022/361.pdf). +//! +//! Since the RFC specifies the encoding function on all inputs and the decoding function on all +//! possible encoded outputs, the differences between implementations come from the decoding +//! function which may be more or less permissive. In this crate, the decoding function of canonical +//! encodings rejects all inputs that are not a possible output of the encoding function. Here are +//! some concrete examples of decoding differences between this crate, the `base64` crate, and the +//! `base64` GNU program: +//! +//! | Input | `data-encoding` | `base64` | GNU `base64` | +//! | ---------- | --------------- | --------- | ------------- | +//! | `AAB=` | `Trailing(2)` | `Last(2)` | `\x00\x00` | +//! | `AA\nB=` | `Length(4)` | `Byte(2)` | `\x00\x00` | +//! | `AAB` | `Length(0)` | `Padding` | Invalid input | +//! | `AAA` | `Length(0)` | `Padding` | Invalid input | +//! | `A\rA\nB=` | `Length(4)` | `Byte(1)` | Invalid input | +//! | `-_\r\n` | `Symbol(0)` | `Byte(0)` | Invalid input | +//! | `AA==AA==` | `[0, 0]` | `Byte(2)` | `\x00\x00` | +//! +//! We can summarize these discrepancies as follows: +//! +//! | Discrepancy | `data-encoding` | `base64` | GNU `base64` | +//! | -------------------------- | --------------- | -------- | ------------ | +//! | Check trailing bits | Yes | Yes | No | +//! | Ignored characters | None | None | `\n` | +//! | Translated characters | None | None | None | +//! | Check padding | Yes | No | Yes | +//! | Support concatenated input | Yes | No | Yes | +//! +//! This crate permits to disable checking trailing bits. It permits to ignore some characters. It +//! permits to translate characters. It permits to use unpadded encodings. However, for padded +//! encodings, support for concatenated inputs cannot be disabled.

This crate encodes to ASCII, so only values +/// smaller than 128 are allowed. +/// +/// More precisely, we need the following elements: +/// +/// - The bit-width N: 1 for binary, 2 for base4, 3 for octal, 4 for hexadecimal, 5 for base32, and +/// 6 for base64 +/// - The [bit-order](enum.BitOrder.html): most or least significant bit first +/// - The symbols function S from [0, 2N) (called values and written `uN`) to symbols +/// (represented as `u8` although only ASCII symbols are allowed, i.e. smaller than 128) +/// - The values partial function V from ASCII to [0, 2N), i.e. from `u8` to `uN` +/// - Whether trailing bits are checked: trailing bits are leading zeros in theory, but since +/// numbers are little-endian they come last +/// +/// For the encoding to be correct (i.e. encoding then decoding gives back the initial input), +/// V(S(i)) must be defined and equal to i for all i in [0, 2N). For the encoding to be +/// [canonical][canonical] (i.e. different inputs decode to different outputs, or equivalently, +/// decoding then encoding gives back the initial input), trailing bits must be checked and if V(i) +/// is defined then S(V(i)) is equal to i for all i. +/// +/// Encoding and decoding are given by the following pipeline: +/// +/// ```text +/// [u8] <--1--> [[bit; 8]] <--2--> [[bit; N]] <--3--> [uN] <--4--> [u8] +/// 1: Map bit-order between each u8 and [bit; 8] +/// 2: Base conversion between base 2^8 and base 2^N (check trailing bits) +/// 3: Map bit-order between each [bit; N] and uN +/// 4: Map symbols/values between each uN and u8 (values must be defined) +/// ``` +/// +/// ## Extensions +/// +/// All these extensions make the encoding not canonical. +/// +/// ### Padding +/// +/// Padding is useful if the following conditions are met: +/// +/// - the bit-width is 3 (octal), 5 (base32), or 6 (base64) +/// - the length of the data to encode is not known in advance +/// - the data must be sent without buffering +/// +/// Bases for which the bit-width N does not divide 8 may not concatenate encoded data. This comes +/// from the fact that it is not possible to make the difference between trailing bits and encoding +/// bits. Padding solves this issue by adding a new character to discriminate between trailing bits +/// and encoding bits. The idea is to work by blocks of lcm(8, N) bits, where lcm(8, N) is the least +/// common multiple of 8 and N. When such block is not complete, it is padded. +/// +/// To preserve correctness, the padding character must not be a symbol. +/// +/// ### Ignore characters when decoding +/// +/// Ignoring characters when decoding is useful if after encoding some characters are added for +/// convenience or any other reason (like wrapping). In that case we want to first ignore those +/// characters before decoding. +/// +/// To preserve correctness, ignored characters must not contain symbols or the padding character. +/// +/// ### Wrap output when encoding +/// +/// Wrapping output when encoding is useful if the output is meant to be printed in a document where +/// width is limited (typically 80-columns documents). In that case, the wrapping width and the +/// wrapping separator have to be defined. +/// +/// To preserve correctness, the wrapping separator characters must be ignored (see previous +/// subsection). As such, wrapping separator characters must also not contain symbols or the padding +/// character. +/// +/// ### Translate characters when decoding +/// +/// Translating characters when decoding is useful when encoded data may be copied by a humain +/// instead of a machine. Humans tend to confuse some characters for others. In that case we want to +/// translate those characters before decoding. +/// +/// To preserve correctness, the characters we translate _from_ must not contain symbols or the +/// padding character, and the characters we translate _to_ must only contain symbols or the padding +/// character. +/// +/// # Practice +/// +/// ## Basics +/// +/// ```rust +/// use data_encoding::{Encoding, Specification}; +/// fn make_encoding(symbols: &str) -> Encoding { +/// let mut spec = Specification::new(); +/// spec.symbols.push_str(symbols); +/// spec.encoding().unwrap() +/// } +/// let binary = make_encoding("01"); +/// let octal = make_encoding("01234567"); +/// let hexadecimal = make_encoding("0123456789abcdef"); +/// assert_eq!(binary.encode(b"Bit"), "010000100110100101110100"); +/// assert_eq!(octal.encode(b"Bit"), "20464564"); +/// assert_eq!(hexadecimal.encode(b"Bit"), "426974"); +/// ``` +/// +/// The `binary` base has 2 symbols `0` and `1` with value 0 and 1 respectively. The `octal` base +/// has 8 symbols `0` to `7` with value 0 to 7. The `hexadecimal` base has 16 symbols `0` to `9` and +/// `a` to `f` with value 0 to 15. The following diagram gives the idea of how encoding works in the +/// previous example (note that we can actually write such diagram only because the bit-order is +/// most significant first): +/// +/// ```text +/// [ octal] | 2 : 0 : 4 : 6 : 4 : 5 : 6 : 4 | +/// [ binary] |0 1 0 0 0 0 1 0|0 1 1 0 1 0 0 1|0 1 1 1 0 1 0 0| +/// [hexadecimal] | 4 : 2 | 6 : 9 | 7 : 4 | +/// ^-- LSB ^-- MSB +/// ``` +/// +/// Note that in theory, these little-endian numbers are read from right to left (the most +/// significant bit is at the right). Since leading zeros are meaningless (in our usual decimal +/// notation 0123 is the same as 123), it explains why trailing bits must be zero. Trailing bits may +/// occur when the bit-width of a base does not divide 8. Only binary, base4, and hexadecimal don't +/// have trailing bits issues. So let's consider octal and base64, which have trailing bits in +/// similar circumstances: +/// +/// ```rust +/// use data_encoding::{Specification, BASE64_NOPAD}; +/// let octal = { +/// let mut spec = Specification::new(); +/// spec.symbols.push_str("01234567"); +/// spec.encoding().unwrap() +/// }; +/// assert_eq!(BASE64_NOPAD.encode(b"B"), "Qg"); +/// assert_eq!(octal.encode(b"B"), "204"); +/// ``` +/// +/// We have the following diagram, where the base64 values are written between parentheses: +/// +/// ```text +/// [base64] | Q(16) : g(32) : [has 4 zero trailing bits] +/// [ octal] | 2 : 0 : 4 : [has 1 zero trailing bit ] +/// |0 1 0 0 0 0 1 0|0 0 0 0 +/// [ ascii] | B | +/// ^-^-^-^-- leading zeros / trailing bits +/// ``` +/// +/// ## Extensions +/// +/// ### Padding +/// +/// For octal and base64, lcm(8, 3) == lcm(8, 6) == 24 bits or 3 bytes. For base32, lcm(8, 5) is 40 +/// bits or 5 bytes. Let's consider octal and base64: +/// +/// ```rust +/// use data_encoding::{Specification, BASE64}; +/// let octal = { +/// let mut spec = Specification::new(); +/// spec.symbols.push_str("01234567"); +/// spec.padding = Some('='); +/// spec.encoding().unwrap() +/// }; +/// // We start encoding but we only have "B" for now. +/// assert_eq!(BASE64.encode(b"B"), "Qg=="); +/// assert_eq!(octal.encode(b"B"), "204====="); +/// // Now we have "it". +/// assert_eq!(BASE64.encode(b"it"), "aXQ="); +/// assert_eq!(octal.encode(b"it"), "322720=="); +/// // By concatenating everything, we may decode the original data. +/// assert_eq!(BASE64.decode(b"Qg==aXQ=").unwrap(), b"Bit"); +/// assert_eq!(octal.decode(b"204=====322720==").unwrap(), b"Bit"); +/// ``` +/// +/// We have the following diagrams: +/// +/// ```text +/// [base64] | Q(16) : g(32) : = : = | +/// [ octal] | 2 : 0 : 4 : = : = : = : = : = | +/// |0 1 0 0 0 0 1 0|. . . . . . . .|. . . . . . . .| +/// [ ascii] | B | end of block aligned --^ +/// ^-- beginning of block aligned +/// +/// [base64] | a(26) : X(23) : Q(16) : = | +/// [ octal] | 3 : 2 : 2 : 7 : 2 : 0 : = : = | +/// |0 1 1 0 1 0 0 1|0 1 1 1 0 1 0 0|. . . . . . . .| +/// [ ascii] | i | t | +/// ``` +/// +/// ### Ignore characters when decoding +/// +/// The typical use-case is to ignore newlines (`\r` and `\n`). But to keep the example small, we +/// will ignore spaces. +/// +/// ```rust +/// let mut spec = data_encoding::HEXLOWER.specification(); +/// spec.ignore.push_str(" \t"); +/// let base = spec.encoding().unwrap(); +/// assert_eq!(base.decode(b"42 69 74"), base.decode(b"426974")); +/// ``` +/// +/// ### Wrap output when encoding +/// +/// The typical use-case is to wrap after 64 or 76 characters with a newline (`\r\n` or `\n`). But +/// to keep the example small, we will wrap after 8 characters with a space. +/// +/// ```rust +/// let mut spec = data_encoding::BASE64.specification(); +/// spec.wrap.width = 8; +/// spec.wrap.separator.push_str(" "); +/// let base64 = spec.encoding().unwrap(); +/// assert_eq!(base64.encode(b"Hey you"), "SGV5IHlv dQ== "); +/// ``` +/// +/// Note that the output always ends with the separator. +/// +/// ### Translate characters when decoding +/// +/// The typical use-case is to translate lowercase to uppercase or reciprocally, but it is also used +/// for letters that look alike, like `O0` or `Il1`. Let's illustrate both examples. +/// +/// ```rust +/// let mut spec = data_encoding::HEXLOWER.specification(); +/// spec.translate.from.push_str("ABCDEFOIl"); +/// spec.translate.to.push_str("abcdef011"); +/// let base = spec.encoding().unwrap(); +/// assert_eq!(base.decode(b"BOIl"), base.decode(b"b011")); +/// ``` +/// +/// [base-conversion]: https://en.wikipedia.org/wiki/Positional_notation#Base_conversion +/// [canonical]: https://tools.ietf.org/html/rfc4648#section-3.5 +#[derive(Debug, Clone)] +#[cfg(feature = "alloc")] +pub struct Specification { + /// Symbols + /// + /// The number of symbols must be 2, 4, 8, 16, 32, or 64.

Implementation of `event-listener` built exclusively on atomics. +//! +//! On `no_std`, we don't have access to `Mutex`, so we can't use intrusive linked lists like the `std` +//! implementation. Normally, we would use a concurrent atomic queue to store listeners, but benchmarks +//! show that using queues in this way is very slow, especially for the single threaded use-case. +//! +//! We've found that it's easier to assume that the `Event` won't be under high contention in most use +//! cases. Therefore, we use a spinlock that protects a linked list of listeners, and fall back to an +//! atomic queue if the lock is contended. Benchmarks show that this is about 20% slower than the std +//! implementation, but still much faster than using a queue. + +#[path = "no_std/node.rs"] +mod node; + +use node::{Node, NothingProducer, TaskWaiting}; + +use crate::notify::{GenericNotify, Internal, Notification}; +use crate::sync::atomic::{AtomicBool, Ordering}; +use crate::sync::cell::{Cell, ConstPtr, UnsafeCell}; +use crate::sync::Arc; +use crate::{RegisterResult, State, Task, TaskRef}; + +use core::fmt; +use core::marker::PhantomData; +use core::mem; +use core::num::NonZeroUsize; +use core::ops; +use core::pin::Pin; + +use alloc::vec::Vec; + +impl crate::Inner { + /// Locks the list. + fn try_lock(&self) -> Option> { + self.list.inner.try_lock().map(|guard| ListGuard { + inner: self, + guard: Some(guard), + tasks: alloc::vec![], + }) + } + + /// Force a queue update. + fn queue_update(&self) { + // Locking and unlocking the mutex will drain the queue if there is no contention. + drop(self.try_lock()); + } + + /// Add a new listener to the list. + /// + /// Does nothing if the list is already registered. + pub(crate) fn insert(&self, mut listener: Pin<&mut Option>>) { + if listener.as_ref().as_pin_ref().is_some() { + // Already inserted. + return; + } + + match self.try_lock() { + Some(mut lock) => { + let key = lock.insert(State::Created); + *listener = Some(Listener::HasNode(key)); + } + + None => { + // Push it to the queue. + let (node, task_waiting) = Node::listener(); + self.list.queue.push(node).unwrap(); + *listener = Some(Listener::Queued(task_waiting)); + + // Force a queue update. + self.queue_update(); + } + } + } + + /// Remove a listener from the list. + pub(crate) fn remove( + &self, + mut listener: Pin<&mut Option>>, + propagate: bool, + ) -> Option> { + loop { + let state = match listener.as_mut().take() { + Some(Listener::HasNode(key)) => { + match self.try_lock() { + Some(mut list) => { + // Fast path removal. + list.remove(key, propagate) + } + + None => { + // Slow path removal. + // This is why intrusive lists don't work on no_std. + let node = Node::RemoveListener { + listener: key, + propagate, + }; + + self.list.queue.push(node).unwrap(); + + // Force a queue update. + self.queue_update(); + + None + } + } + } + + Some(Listener::Queued(tw)) => { + // Make sure it's not added after the queue is drained. + if let Some(key) = tw.cancel() { + // If it was already added, set up our listener and try again. + *listener = Some(Listener::HasNode(key)); + continue; + } + + None + } + + None => None, + + _ => unreachable!(), + }; + + return state; + } + } + + /// Notifies a number of entries. + #[cold] + pub(crate) fn notify(&self, notify: impl Notification) -> usize { + match self.try_lock() { + Some(mut guard) => { + // Notify the listeners. + guard.notify(notify) + } + + None => { + // Push it to the queue. + let node = Node::Notify(GenericNotify::new( + notify.count(Internal::new()), + notify.is_additional(Internal::new()), + NothingProducer::default(), + )); + + self.list.queue.push(node).unwrap(); + + // Force a queue update. + self.queue_update(); + + // We haven't notified anyone yet. + 0 + } + } + } + + /// Register a task to be notified when the event is triggered. + /// + /// Returns `true` if the listener was already notified, and `false` otherwise.

Standard header names are +//! special cased and are represented internally as an enum. Short custom +//! headers will be stored directly in the `HeaderName` struct and will not +//! incur any allocation overhead, however longer strings will require an +//! allocation for storage. +//! +//! ## Limitations +//! +//! `HeaderName` has a max length of 32,768 for header names. Attempting to +//! parse longer names will result in a panic. +//! +//! # `HeaderMap` +//! +//! `HeaderMap` is a map structure of header names highly optimized for use +//! cases common with HTTP. It is a [multimap] structure, where each header name +//! may have multiple associated header values. Given this, some of the APIs +//! diverge from [`HashMap`]. +//! +//! ## Overview +//! +//! Just like `HashMap` in Rust's stdlib, `HeaderMap` is based on [Robin Hood +//! hashing]. This algorithm tends to reduce the worst case search times in the +//! table and enables high load factors without seriously affecting performance. +//! Internally, keys and values are stored in vectors. As such, each insertion +//! will not incur allocation overhead. However, once the underlying vector +//! storage is full, a larger vector must be allocated and all values copied. +//! +//! ## Deterministic ordering +//! +//! Unlike Rust's `HashMap`, values in `HeaderMap` are deterministically +//! ordered. Roughly, values are ordered by insertion. This means that a +//! function that deterministically operates on a header map can rely on the +//! iteration order to remain consistent across processes and platforms. +//! +//! ## Adaptive hashing +//! +//! `HeaderMap` uses an adaptive hashing strategy in order to efficiently handle +//! most common cases. All standard headers have statically computed hash values +//! which removes the need to perform any hashing of these headers at runtime. +//! The default hash function emphasizes performance over robustness. However, +//! `HeaderMap` detects high collision rates and switches to a secure hash +//! function in those events. The threshold is set such that only denial of +//! service attacks should trigger it. +//! +//! ## Limitations +//! +//! `HeaderMap` can store a maximum of 32,768 headers (header name / value +//! pairs). Attempting to insert more will result in a panic. +//! +//! [`HeaderName`]: struct.HeaderName.html +//! [`HeaderMap`]: struct.HeaderMap.html +//!

A general purpose library of common HTTP types +//! +//! This crate is a general purpose library for common types found when working +//! with the HTTP protocol. You'll find `Request` and `Response` types for +//! working as either a client or a server as well as all of their components. +//! Notably you'll find `Uri` for what a `Request` is requesting, a `Method` +//! for how it's being requested, a `StatusCode` for what sort of response came +//! back, a `Version` for how this was communicated, and +//! `HeaderName`/`HeaderValue` definitions to get grouped in a `HeaderMap` to +//! work with request/response headers. +//! +//! You will notably *not* find an implementation of sending requests or +//! spinning up a server in this crate. It's intended that this crate is the +//! "standard library" for HTTP clients and servers without dictating any +//! particular implementation. Note that this crate is still early on in its +//! lifecycle so the support libraries that integrate with the `http` crate are +//! a work in progress! Stay tuned and we'll be sure to highlight crates here +//! in the future. +//! +//! ## Requests and Responses +//! +//! Perhaps the main two types in this crate are the `Request` and `Response` +//! types. A `Request` could either be constructed to get sent off as a client +//! or it can also be received to generate a `Response` for a server. Similarly +//! as a client a `Response` is what you get after sending a `Request`, whereas +//! on a server you'll be manufacturing a `Response` to send back to the client. +//! +//! Each type has a number of accessors for the component fields. For as a +//! server you might want to inspect a requests URI to dispatch it: +//! +//! ``` +//! use http::{Request, Response}; +//! +//! fn response(req: Request<()>) -> http::Result> { +//! match req.uri().path() { +//! "/" => index(req), +//! "/foo" => foo(req), +//! "/bar" => bar(req), +//! _ => not_found(req), +//! } +//! } +//! # fn index(_req: Request<()>) -> http::Result> { panic!() } +//! # fn foo(_req: Request<()>) -> http::Result> { panic!() } +//! # fn bar(_req: Request<()>) -> http::Result> { panic!() } +//! # fn not_found(_req: Request<()>) -> http::Result> { panic!() } +//! ``` +//! +//! On a `Request` you'll also find accessors like `method` to return a +//! `Method` and `headers` to inspect the various headers. A `Response` +//! has similar methods for headers, the status code, etc. +//! +//! In addition to getters, request/response types also have mutable accessors +//! to edit the request/response: +//! +//! ``` +//! use http::{HeaderValue, Response, StatusCode}; +//! use http::header::CONTENT_TYPE; +//! +//! fn add_server_headers(response: &mut Response) { +//! response.headers_mut() +//! .insert(CONTENT_TYPE, HeaderValue::from_static("text/html")); +//! *response.status_mut() = StatusCode::OK; +//! } +//! ``` +//! +//! And finally, one of the most important aspects of requests/responses, the +//! body! The `Request` and `Response` types in this crate are *generic* in +//! what their body is. This allows downstream libraries to use different +//! representations such as `Request>`, `Response`, +//! `Request, Error = _>>`, or even +//! `Response` where the custom type was deserialized from JSON. +//! +//! The body representation is intentionally flexible to give downstream +//! libraries maximal flexibility in implementing the body as appropriate. +//! +//! ## HTTP Headers +//! +//! Another major piece of functionality in this library is HTTP header +//! interpretation and generation. The `HeaderName` type serves as a way to +//! define header *names*, or what's to the left of the colon. A `HeaderValue` +//! conversely is the header *value*, or what's to the right of a colon. +//! +//! For example, if you have an HTTP request that looks like: +//! +//! ```http +//! GET /foo HTTP/1.1 +//! Accept: text/html +//! ``` +//! +//! Then `"Accept"` is a `HeaderName` while `"text/html"` is a `HeaderValue`. +//! Each of these is a dedicated type to allow for a number of interesting +//! optimizations and to also encode the static guarantees of each type. For +//! example a `HeaderName` is always a valid `&str`, but a `HeaderValue` may +//! not be valid UTF-8. +//! +//! The most common header names are already defined for you as constant values +//! in the `header` module of this crate. For example: +//! +//! ``` +//! use http::header::{self, HeaderName}; +//! +//! let name: HeaderName = header::ACCEPT; +//! assert_eq!(name.as_str(), "accept"); +//! ``` +//! +//! You can, however, also parse header names from strings: +//! +//! ``` +//! use http::header::{self, HeaderName}; +//! +//! let name = "Accept".parse::().unwrap(); +//! assert_eq!(name, header::ACCEPT); +//! ``` +//! +//! Header values can be created from string literals through the `from_static` +//! function: +//! +//! ``` +//! use http::HeaderValue; +//! +//! let value = HeaderValue::from_static("text/html"); +//! assert_eq!(value.as_bytes(), b"text/html"); +//! ``` +//! +//! And header values can also be parsed like names: +//! +//! ``` +//! use http::HeaderValue; +//! +//! let value = "text/html"; +//! let value = value.parse::().unwrap(); +//! ``` +//! +//! Most HTTP requests and responses tend to come with more than one header, so +//! it's not too useful to just work with names and values only! This crate also +//! provides a `HeaderMap` type which is a specialized hash map for keys as +//! `HeaderName` and generic values. This type, like header names, is optimized +//! for common usage but should continue to scale with your needs over time. +//! +//! # URIs +//! +//! Each HTTP `Request` has an associated URI with it. This may just be a path +//! like `/index.html` but it could also be an absolute URL such as +//! `https://www.rust-lang.org/index.html`. A `URI` has a number of accessors to +//! interpret it: +//! +//! ``` +//! use http::Uri; +//! use http::uri::Scheme; +//! +//! let uri = "https://www.rust-lang.org/index.html".parse::().unwrap(); +//! +//! assert_eq!(uri.scheme(), Some(&Scheme::HTTPS)); +//! assert_eq!(uri.host(), Some("www.rust-lang.org")); +//! assert_eq!(uri.path(), "/index.html"); +//! assert_eq!(uri.query(), None); +//! ``` + +#![deny(missing_docs, missing_debug_implementations)] + +#[cfg(test)] +#[macro_use] +extern crate doc_comment; + +#[cfg(test)] +doctest!("../README.md"); + +#[macro_use] +mod convert; + +pub mod header; +pub mod method; +pub mod request; +pub mod response; +pub mod status; +pub mod uri; +pub mod version; + +mod byte_str; +mod error; +mod extensions; + +pub use crate::error::{Error, Result}; +pub use crate::extensions::Extensions; +#[doc(no_inline)] +pub use crate::header::{HeaderMap, HeaderName, HeaderValue}; +pub use crate::method::Method; +pub use crate::request::Request; +pub use crate::response::Response; +pub use crate::status::StatusCode; +pub use crate::uri::Uri; +pub use crate::version::Version; + +fn _assert_types() { + fn assert_send() {} + fn assert_sync() {} + + assert_send::>(); + assert_send::>(); + + assert_sync::>(); + assert_sync::>(); +} + +mod sealed { + /// Private trait to this crate to prevent traits from being implemented in + /// downstream crates. + pub trait Sealed {} +} diff --git a/.cargo-vendor/http-0.2.12/src/method.rs b/.cargo-vendor/http-0.2.12/src/method.rs new file mode 100644 index 0000000000..04261a37ab --- /dev/null +++ b/.cargo-vendor/http-0.2.12/src/method.rs @@ -0,0 +1,473 @@ +//!

Neither is enabled by default. See the `Cargo.toml` for more information. If you require support for secure WebSockets (`wss://`) enable one of them. + +## Is it performant? + +In essence, `tokio-tungstenite` is a wrapper for `tungstenite`, so the performance is capped by the performance of `tungstenite`. `tungstenite` +has a decent performance (it has been used in production for real-time communication software, video conferencing, etc), but it's definitely +not the fastest WebSocket library in the world at the moment of writing this note. + +If performance is of a paramount importance for you (especially if you send **large messages**), then you might want to check other libraries +that have been designed to be performant or you could file a PR against `tungstenite` to improve the performance! + +We are aware of changes that both `tungstenite` and `tokio-tungstenite` need in order to fill the gap of ~30% performance difference between `tungstenite` +and more performant libraries like `fastwebsockets`, but we have not worked on that yet as it was not required for the use case that original authors designed +the library for. In the course of past years we have merged several performance improvements submitted by the awesome community of Rust users who helped to improve +the library!

For example if you're using [`ServerErrorsAsFailures`] as your classifier +//! and the inner service responds with `500 Internal Server Error` then the +//! `on_response` callback is still called. `on_failure` would _also_ be called +//! in this case since the response was classified as a failure. +//! +//! ### `on_body_chunk` +//! +//! The `on_body_chunk` callback is called when the response body produces a new +//! chunk, that is when [`Body::poll_frame`] returns a data frame. +//! +//! `on_body_chunk` is called even if the chunk is empty. +//! +//! ### `on_eos` +//! +//! The `on_eos` callback is called when a streaming response body ends, that is +//! when [`Body::poll_frame`] returns a trailers frame. +//! +//! `on_eos` is called even if the trailers produced are `None`. +//! +//! ### `on_failure` +//! +//! The `on_failure` callback is called when: +//! +//! - The inner [`Service`]'s response future resolves to an error. +//! - A response is classified as a failure. +//! - [`Body::poll_frame`] returns an error. +//! - An end-of-stream is classified as a failure. +//! +//! # Recording fields on the span +//! +//! All callbacks receive a reference to the [tracing] [`Span`], corresponding to this request, +//! produced by the closure passed to [`TraceLayer::make_span_with`].

It allows for both synchronous (like TcpStream) +and asynchronous usage and is easy to integrate into any third-party event loops including +[MIO](https://github.com/tokio-rs/mio). The API design abstracts away all the internals of the +WebSocket protocol but still makes them accessible for those who wants full control over the +network. + +Why Tungstenite? +---------------- + +It's formerly WS2, the 2nd implementation of WS. WS2 is the chemical formula of +tungsten disulfide, the tungstenite mineral. + +Features +-------- + +Tungstenite provides a complete implementation of the WebSocket specification. +TLS is supported on all platforms using `native-tls` or `rustls`. The following +features are available: + +* `native-tls` +* `native-tls-vendored` +* `rustls-tls-native-roots` +* `rustls-tls-webpki-roots` + +Choose the one that is appropriate for your needs. + +By default **no TLS feature is activated**, so make sure you use one of the TLS features, +otherwise you won't be able to communicate with the TLS endpoints. + +There is no support for permessage-deflate at the moment, but the PRs are welcome :wink: + +Testing +------- + +Tungstenite is thoroughly tested and passes the [Autobahn Test Suite](https://github.com/crossbario/autobahn-testsuite) for +WebSockets. It is also covered by internal unit tests as well as possible. + +Contributing +------------ + +Please report bugs and make feature requests [here](https://github.com/snapview/tungstenite-rs/issues). diff --git a/.cargo-vendor/tungstenite/benches/buffer.rs b/.cargo-vendor/tungstenite/benches/buffer.rs new file mode 100644 index 0000000000..9f15d1384b --- /dev/null +++ b/.cargo-vendor/tungstenite/benches/buffer.rs @@ -0,0 +1,126 @@ +use std::io::{Cursor, Read, Result as IoResult}; + +use bytes::Buf; +use criterion::*; +use input_buffer::InputBuffer; + +use tungstenite::buffer::ReadBuffer; + +const CHUNK_SIZE: usize = 4096; + +/// A FIFO buffer for reading packets from the network. +#[derive(Debug)] +pub struct StackReadBuffer { + storage: Cursor>, + chunk: [u8; CHUNK_SIZE], +} + +impl StackReadBuffer { + /// Create a new empty input buffer. + pub fn new() -> Self { + Self::with_capacity(CHUNK_SIZE) + } + + /// Create a new empty input buffer with a given `capacity`. + pub fn with_capacity(capacity: usize) -> Self { + Self::from_partially_read(Vec::with_capacity(capacity)) + } + + /// Create a input buffer filled with previously read data. + pub fn from_partially_read(part: Vec) -> Self { + Self { storage: Cursor::new(part), chunk: [0; CHUNK_SIZE] } + } + + /// Get a cursor to the data storage. + pub fn as_cursor(&self) -> &Cursor> { + &self.storage + } + + /// Get a cursor to the mutable data storage. + pub fn as_cursor_mut(&mut self) -> &mut Cursor> { + &mut self.storage + } + + /// Consume the `ReadBuffer` and get the internal storage. + pub fn into_vec(mut self) -> Vec { + // Current implementation of `tungstenite-rs` expects that the `into_vec()` drains + // the data from the container that has already been read by the cursor. + self.clean_up(); + + // Now we can safely return the internal container. + self.storage.into_inner() + } + + /// Read next portion of data from the given input stream. + pub fn read_from(&mut self, stream: &mut S) -> IoResult { + self.clean_up(); + let size = stream.read(&mut self.chunk)?; + self.storage.get_mut().extend_from_slice(&self.chunk[..size]); + Ok(size) + } + + /// Cleans ups the part of the vector that has been already read by the cursor. + fn clean_up(&mut self) { + let pos = self.storage.position() as usize; + self.storage.get_mut().drain(0..pos).count(); + self.storage.set_position(0); + } +} + +impl Buf for StackReadBuffer { + fn remaining(&self) -> usize { + Buf::remaining(self.as_cursor()) + } + + fn chunk(&self) -> &[u8] { + Buf::chunk(self.as_cursor()) + } + + fn advance(&mut self, cnt: usize) { + Buf::advance(self.as_cursor_mut(), cnt) + } +} + +impl Default for StackReadBuffer { + fn default() -> Self { + Self::new() + } +} + +#[inline] +fn input_buffer(mut stream: impl Read) { + let mut buffer = InputBuffer::with_capacity(CHUNK_SIZE); + while buffer.read_from(&mut stream).unwrap() != 0 {} +} + +#[inline] +fn stack_read_buffer(mut stream: impl Read) { + let mut buffer = StackReadBuffer::::new(); + while buffer.read_from(&mut stream).unwrap() != 0 {} +} + +#[inline] +fn heap_read_buffer(mut stream: impl Read) { + let mut buffer = ReadBuffer::::new(); + while buffer.read_from(&mut stream).unwrap() != 0 {} +} + +fn benchmark(c: &mut Criterion) { + const STREAM_SIZE: usize = 1024 * 1024 * 4; + let data: Vec = (0..STREAM_SIZE).map(|_| rand::random()).collect(); + let stream = Cursor::new(data); + + let mut group = c.benchmark_group("buffers"); + group.throughput(Throughput::Bytes(STREAM_SIZE as u64)); + group.bench_function("InputBuffer", |b| b.iter(|| input_buffer(black_box(stream.clone())))); + group.bench_function("ReadBuffer (stack)", |b| { + b.iter(|| stack_read_buffer(black_box(stream.clone()))) + }); + group.bench_function("ReadBuffer (heap)", |b| { + b.iter(|| heap_read_buffer(black_box(stream.clone()))) + }); + group.finish(); +} + +criterion_group!(benches, benchmark); +criterion_main!(benches); diff --git a/.cargo-vendor/tungstenite/benches/write.rs b/.cargo-vendor/tungstenite/benches/write.rs new file mode 100644 index 0000000000..7908818395 --- /dev/null +++ b/.cargo-vendor/tungstenite/benches/write.rs @@ -0,0 +1,75 @@ +//!
