+// Useful for rewriting out a buffered input token stream after doing some
+// augmentation or other manipulations on it.
+
+//
+// You can insert stuff, replace, and delete chunks. Note that the operations
+// are done lazily--only if you convert the buffer to a {@link String} with
+// {@link TokenStream#getText()}. This is very efficient because you are not
+// moving data around all the time. As the buffer of tokens is converted to
+// strings, the {@link #getText()} method(s) scan the input token stream and
+// check to see if there is an operation at the current index. If so, the
+// operation is done and then normal {@link String} rendering continues on the
+// buffer. This is like having multiple Turing machine instruction streams
+// (programs) operating on a single input tape. :)
+//
+
+// This rewriter makes no modifications to the token stream. It does not ask the
+// stream to fill itself up nor does it advance the input cursor. The token
+// stream {@link TokenStream#index()} will return the same value before and
+// after any {@link #getText()} call.
+
+//
+// The rewriter only works on tokens that you have in the buffer and ignores the
+// current input cursor. If you are buffering tokens on-demand, calling
+// {@link #getText()} halfway through the input will only do rewrites for those
+// tokens in the first half of the file.
+
+//
+// Since the operations are done lazily at {@link #getText}-time, operations do
+// not screw up the token index values. That is, an insert operation at token
+// index {@code i} does not change the index values for tokens
+// {@code i}+1..n-1.
+
+//
+// Because operations never actually alter the buffer, you may always get the
+// original token stream back without undoing anything. Since the instructions
+// are queued up, you can easily simulate transactions and roll back any changes
+// if there is an error just by removing instructions. For example,
+
+//
+// CharStream input = new ANTLRFileStream("input");
+// TLexer lex = new TLexer(input);
+// CommonTokenStream tokens = new CommonTokenStream(lex);
+// T parser = new T(tokens);
+// TokenStreamRewriter rewriter = new TokenStreamRewriter(tokens);
+// parser.startRule();
+//
+
+//
+// Then in the rules, you can execute (assuming rewriter is visible):
+
+//
+// Token t,u;
+// ...
+// rewriter.insertAfter(t, "text to put after t");}
+// rewriter.insertAfter(u, "text after u");}
+// System.out.println(rewriter.getText());
+//
+
+//
+// You can also have multiple "instruction streams" and get multiple rewrites
+// from a single pass over the input. Just name the instruction streams and use
+// that name again when printing the buffer. This could be useful for generating
+// a C file and also its header file--all from the same buffer:
+
+//
+// rewriter.insertAfter("pass1", t, "text to put after t");}
+// rewriter.insertAfter("pass2", u, "text after u");}
+// System.out.println(rewriter.getText("pass1"));
+// System.out.println(rewriter.getText("pass2"));
+//
+
+//
+// If you don't use named rewrite streams, a "default" stream is used as the
+// first example shows.

+# :zap: Zapdriver
+
+Blazing fast, [Zap][zap]-based [Stackdriver][stackdriver] logging.
+
+[zap]: https://github.com/uber-go/zap
+[stackdriver]: https://cloud.google.com/stackdriver/
+
+## Usage
+
+This package provides three building blocks to support the full array of
+structured logging capabilities of Stackdriver:
+
+* [Special purpose logging fields](#special-purpose-logging-fields)
+* [Pre-configured Stackdriver-optimized encoder](#pre-configured-stackdriver-optimized-encoder)
+* [Custom Stackdriver Zap core](#custom-stackdriver-zap-core)
+* [Using Error Reporting](#using-error-reporting)
+
+The above components can be used separately, but to start, you can create a new
+Zap logger with all of the above included:
+
+```golang
+logger, err := zapdriver.NewProduction() // with sampling
+logger, err := zapdriver.NewDevelopment() // with `development` set to `true`
+```
+
+The above functions give back a pointer to a `zap.Logger` object, so you can use
+[Zap][zap] like you've always done, except that it now logs in the proper
+[Stackdriver][stackdriver] format.
+
+You can also create a configuration struct, and build your logger from there:
+
+```golang
+config := zapdriver.NewProductionConfig()
+config := zapdriver.NewDevelopmentConfig()
+```
+
+Or, get the Zapdriver encoder, and build your own configuration struct from
+that:
+
+```golang
+encoder := zapdriver.NewProductionEncoderConfig()
+encoder := zapdriver.NewDevelopmentEncoderConfig()
+```
+
+Read on to learn more about the available Stackdriver-specific log fields, and
+how to use the above-mentioned components.
+
+### Special purpose logging fields
+
+You can use the following fields to add extra information to your log entries.
+These fields are parsed by Stackdriver to make it easier to query your logs or
+to use the log details in the Stackdriver monitoring interface.
+
+* [`HTTP`](#http)
+* [`Label`](#label)
+* [`SourceLocation`](#sourcelocation)
+* [`Operation`](#operation)
+* [`TraceContext`](#tracecontext)
+
+#### HTTP
+
+You can log HTTP request/response cycles using the following field:
+
+```golang
+HTTP(req *HTTPPayload) zap.Field
+```
+
+You can either manually build the request payload:
+
+```golang
+req := &HTTPPayload{
+ RequestMethod: "GET",
+ RequestURL: "/",
+ Status: 200,
+}
+```
+
+Or, you can auto generate the struct, based on the available request and
+response objects:
+
+```golang
+NewHTTP(req *http.Request, res *http.Response) *HTTPPayload
+```
+
+You are free to pass in `nil` for either the request or response object, if one
+of them is unavailable to you at the point of logging. Any field depending on
+one or the other will be omitted if `nil` is passed in.
+
+Note that there are some fields that are not populated by either the request or
+response object, and need to be set manually:
+
+* `ServerIP string`
+* `Latency string`
+* `CacheLookup bool`
+* `CacheHit bool`
+* `CacheValidatedWithOriginServer bool`
+* `CacheFillBytes string`
+
+If you have no need for those fields, the quickest way to get started is like
+so:
+
+```golang
+logger.Info("Request Received.", zapdriver.HTTP(zapdriver.NewHTTP(req, res)))
+```
+
+#### Label
+
+You can add a "label" to your payload as follows:
+
+```golang
+Label(key, value string) zap.Field
+```
+
+Note that underwater, this sets the key to `labels.`. You need to be using
+the `zapdriver.Core` core for this to be converted to the proper format for
+Stackdriver to recognize the labels.
+
+See "Custom Stackdriver Zap core" for more details.
+
+If you have a reason not to use the provided Core, you can still wrap labels in
+the right `labels` namespace by using the available function:
+
+```golang
+Labels(fields ...zap.Field) zap.Field
+```
+
+Like so:
+
+```golang
+logger.Info(
+ "Did something.",
+ zapdriver.Labels(
+ zapdriver.Label("hello", "world"),
+ zapdriver.Label("hi", "universe"),
+ ),
+)
+```
+
+Again, wrapping the `Label` calls in `Labels` is not required if you use the
+supplied Zap Core.
+
+#### SourceLocation
+
+You can add a source code location to your log lines to be picked up by
+Stackdriver.
+
+Note that you can set this manually, or use `zapdriver.Core` to automatically
+add this. If you set it manually, _and_ use `zapdriver.Core`, the manual call
+stack will be preserved over the automated one.
+
+```golang
+SourceLocation(pc uintptr, file string, line int, ok bool) zap.Field
+```
+
+Note that the function signature equals that of the return values of
+`runtime.Caller()`. This allows you to catch the stack frame at one location,
+while logging it at a different location, like so:
+
+```golang
+pc, file, line, ok := runtime.Caller(0)
+
+// do other stuff...
+
+logger.Error("Something happened!", zapdriver.SourceLocation(pc, file, line, ok))
+```
+
+If you use `zapdriver.Core`, the above use-case is the only use-case where you
+would want to manually set the source location. In all other situations, you can
+simply omit this field, and it will be added automatically, using the stack
+frame at the location where the log line is triggered.
+
+If you don't use `zapdriver.Core`, and still want to add the source location at
+the frame of the triggered log line, you'd do it like this:
+
+```golang
+logger.Error("Something happened!", zapdriver.SourceLocation(runtime.Caller(0)))
+```
+
+#### Operation
+
+The `Operation` log field allows you to group log lines into a single
+"operation" performed by the application:
+
+```golang
+Operation(id, producer string, first, last bool) zap.Field
+```
+
+For a pair of logs that belong to the same operation, you should use the same
+`id` between them. The `producer` is an arbitrary identifier that should be
+globally unique amongst all the logs of all your applications (meaning it should
+probably be the unique name of the current application). You should set `first`
+to true for the first log in the operation, and `last` to true for the final log
+of the operation.
+
+```golang
+logger.Info("Started.", zapdriver.Operation("3g4d3g", "my-app", true, false))
+logger.Debug("Progressing.", zapdriver.Operation("3g4d3g", "my-app", false, false))
+logger.Info("Done.", zapdriver.Operation("3g4d3g", "my-app", false, true))
+```
+
+Instead of defining the "start" and "end" booleans, you can also use these three
+convenience functions:
+
+```golang
+OperationStart(id, producer string) zap.Field
+OperationCont(id, producer string) zap.Field
+OperationEnd(id, producer string) zap.Field
+```
+
+#### TraceContext
+
+You can add trace context information to your log lines to be picked up by
+Stackdriver.
+
+```golang
+TraceContext(trace string, spanId string, sampled bool, projectName string) []zap.Field
+```
+
+Like so:
+
+```golang
+logger.Error("Something happened!", zapdriver.TraceContext("105445aa7843bc8bf206b120001000", "0", true, "my-project-name")...)
+```
+
+### Pre-configured Stackdriver-optimized encoder
+
+The Stackdriver encoder maps all Zap log levels to the appropriate
+[Stackdriver-supported levels][levels]:
+
+> DEBUG (100) Debug or trace information.
+>
+> INFO (200) Routine information, such as ongoing status or performance.
+>
+> WARNING (400) Warning events might cause problems.
+>
+> ERROR (500) Error events are likely to cause problems.
+>
+> CRITICAL (600) Critical events cause more severe problems or outages.
+>
+> ALERT (700) A person must take an action immediately.
+>
+> EMERGENCY (800) One or more systems are unusable.
+
+[levels]: https://cloud.google.com/logging/docs/reference/v2/rest/v2/LogEntry#LogSeverity
+
+It also sets some of the default keys to use [the right names][names], such as
+`timestamp`, `severity`, and `message`.
+
+[names]: https://cloud.google.com/logging/docs/reference/v2/rest/v2/LogEntry
+
+You can use this encoder if you want to build your Zap logger configuration
+manually:
+
+```golang
+zapdriver.NewProductionEncoderConfig()
+```
+
+For parity-sake, there's also `zapdriver.NewDevelopmentEncoderConfig()`, but it
+returns the exact same encoder right now.
+
+### Custom Stackdriver Zap core
+
+A custom Zap core is included in this package to support some special use-cases.
+
+First of all, if you use `zapdriver.NewProduction()` (or `NewDevelopment`) , you
+already have this core enabled, so everything _just works_ ™.
+
+There are two use-cases which require this core:
+
+1. If you use `zapdriver.Label("hello", "world")`, it will initially end up in
+ your log with the key `labels.hello` and value `world`. Now if you have two
+ labels, you could also have `labels.hi` with value `universe`. This works as-
+ is, but for this to be correctly parsed by Stackdriver as true "labels", you
+ need to use the Zapdriver core, so that both of these fields get rewritten,
+ to use the namespace `labels`, and use the keys `hello` and `hi` within that
+ namespace. This is done automatically.
+
+2. If you don't want to use `zapdriver.SourceLocation()` on every log call, you
+ can use this core for the source location to be automatically added to
+ each log entry.
+
+When building a logger, you can inject the Zapdriver core as follows:
+
+```golang
+config := &zap.Config{}
+logger, err := config.Build(zapdriver.WrapCore())
+```
+
+### Using Error Reporting
+
+To report errors using StackDriver's Error Reporting tool, a log line needs to follow a separate log format described in the [Error Reporting][errorreporting] documentation.
+
+[errorreporting]: https://cloud.google.com/error-reporting/docs/formatting-error-messages
+
+The simplest way to do this is by using `NewProductionWithCore`:
+
+```golang
+logger, err := zapdriver.NewProductionWithCore(zapdriver.WrapCore(
+ zapdriver.ReportAllErrors(true),
+ zapdriver.ServiceName("my service"),
+))
+```
+
+For parity-sake, there's also `zapdriver.NewDevelopmentWithCore()`
+
+If you are building a custom logger, you can use `WrapCore()` to configure the driver core:
+
+```golang
+config := &zap.Config{}
+logger, err := config.Build(zapdriver.WrapCore(
+ zapdriver.ReportAllErrors(true),
+ zapdriver.ServiceName("my service"),
+))
+```
+
+Configuring this way, every error log entry will be reported to Stackdriver's Error Reporting tool.
+
+#### Reporting errors manually
+
+If you do not want every error to be reported, you can attach `ErrorReport()` to log call manually:
+
+```golang
+logger.Error("An error to be reported!", zapdriver.ErrorReport(runtime.Caller(0)))
+// Or get Caller details
+pc, file, line, ok := runtime.Caller(0)
+// do other stuff... and log elsewhere
+logger.Error("Another error to be reported!", zapdriver.ErrorReport(pc, file, line, ok))
+```
+
+Please keep in mind that ErrorReport needs a ServiceContext attached to the log
+entry. If you did not configure this using `WrapCore`, error reports will
+get attached using service name as `unknown`. To prevent this from happeneing,
+either configure your core or attach service context before (or when) using
+the logger:
+
+```golang
+logger.Error(
+ "An error to be reported!",
+ zapdriver.ErrorReport(runtime.Caller(0)),
+ zapdriver.ServiceContext("my service"),
+)
+
+// Or permanently attach it to your logger
+logger = logger.With(zapdriver.ServiceContext("my service"))
+// and then use it
+logger.Error("An error to be reported!", zapdriver.ErrorReport(runtime.Caller(0)))
+```

+# xxhash
+
+[](https://pkg.go.dev/github.com/cespare/xxhash/v2)
+[](https://github.com/cespare/xxhash/actions/workflows/test.yml)
+
+xxhash is a Go implementation of the 64-bit [xxHash] algorithm, XXH64. This is a
+high-quality hashing algorithm that is much faster than anything in the Go
+standard library.
+
+This package provides a straightforward API:
+
+```
+func Sum64(b []byte) uint64
+func Sum64String(s string) uint64
+type Digest struct{ ... }
+ func New() *Digest
+```
+
+The `Digest` type implements hash.Hash64. Its key methods are:
+
+```
+func (*Digest) Write([]byte) (int, error)
+func (*Digest) WriteString(string) (int, error)
+func (*Digest) Sum64() uint64
+```
+
+The package is written with optimized pure Go and also contains even faster
+assembly implementations for amd64 and arm64. If desired, the `purego` build tag
+opts into using the Go code even on those architectures.
+
+[xxHash]: http://cyan4973.github.io/xxHash/
+
+## Compatibility
+
+This package is in a module and the latest code is in version 2 of the module.
+You need a version of Go with at least "minimal module compatibility" to use
+github.com/cespare/xxhash/v2:
+
+* 1.9.7+ for Go 1.9
+* 1.10.3+ for Go 1.10
+* Go 1.11 or later
+
+I recommend using the latest release of Go.
+
+## Benchmarks
+
+Here are some quick benchmarks comparing the pure-Go and assembly
+implementations of Sum64.
+
+| input size | purego | asm |
+| ---------- | --------- | --------- |
+| 4 B | 1.3 GB/s | 1.2 GB/s |
+| 16 B | 2.9 GB/s | 3.5 GB/s |
+| 100 B | 6.9 GB/s | 8.1 GB/s |
+| 4 KB | 11.7 GB/s | 16.7 GB/s |
+| 10 MB | 12.0 GB/s | 17.3 GB/s |
+
+These numbers were generated on Ubuntu 20.04 with an Intel Xeon Platinum 8252C
+CPU using the following commands under Go 1.19.2:
+
+```
+benchstat <(go test -tags purego -benchtime 500ms -count 15 -bench 'Sum64$')
+benchstat <(go test -benchtime 500ms -count 15 -bench 'Sum64$')
+```

+go-restful
+==========
+package for building REST-style Web Services using Google Go
+
+[](https://travis-ci.org/emicklei/go-restful)
+[](https://goreportcard.com/report/github.com/emicklei/go-restful)
+[](https://pkg.go.dev/github.com/emicklei/go-restful)
+[](https://codecov.io/gh/emicklei/go-restful)
+
+- [Code examples use v3](https://github.com/emicklei/go-restful/tree/v3/examples)
+
+REST asks developers to use HTTP methods explicitly and in a way that's consistent with the protocol definition. This basic REST design principle establishes a one-to-one mapping between create, read, update, and delete (CRUD) operations and HTTP methods. According to this mapping:
+
+- GET = Retrieve a representation of a resource
+- POST = Create if you are sending content to the server to create a subordinate of the specified resource collection, using some server-side algorithm.
+- PUT = Create if you are sending the full content of the specified resource (URI).
+- PUT = Update if you are updating the full content of the specified resource.
+- DELETE = Delete if you are requesting the server to delete the resource
+- PATCH = Update partial content of a resource
+- OPTIONS = Get information about the communication options for the request URI
+
+### Usage
+
+#### Without Go Modules
+
+All versions up to `v2.*.*` (on the master) are not supporting Go modules.
+
+```
+import (
+ restful "github.com/emicklei/go-restful"
+)
+```
+
+#### Using Go Modules
+
+As of version `v3.0.0` (on the v3 branch), this package supports Go modules.
+
+```
+import (
+ restful "github.com/emicklei/go-restful/v3"
+)
+```
+
+### Example
+
+```Go
+ws := new(restful.WebService)
+ws.
+ Path("/users").
+ Consumes(restful.MIME_XML, restful.MIME_JSON).
+ Produces(restful.MIME_JSON, restful.MIME_XML)
+
+ws.Route(ws.GET("/{user-id}").To(u.findUser).
+ Doc("get a user").
+ Param(ws.PathParameter("user-id", "identifier of the user").DataType("string")).
+ Writes(User{}))
+...
+
+func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
+ id := request.PathParameter("user-id")
+ ...
+}
+```
+
+[Full API of a UserResource](https://github.com/emicklei/go-restful/blob/v3/examples/user-resource/restful-user-resource.go)
+
+### Features
+
+- Routes for request → function mapping with path parameter (e.g. {id} but also prefix_{var} and {var}_suffix) support
+- Configurable router:
+ - (default) Fast routing algorithm that allows static elements, [google custom method](https://cloud.google.com/apis/design/custom_methods), regular expressions and dynamic parameters in the URL path (e.g. /resource/name:customVerb, /meetings/{id} or /static/{subpath:*})
+ - Routing algorithm after [JSR311](http://jsr311.java.net/nonav/releases/1.1/spec/spec.html) that is implemented using (but does **not** accept) regular expressions
+- Request API for reading structs from JSON/XML and accessing parameters (path,query,header)
+- Response API for writing structs to JSON/XML and setting headers
+- Customizable encoding using EntityReaderWriter registration
+- Filters for intercepting the request → response flow on Service or Route level
+- Request-scoped variables using attributes
+- Containers for WebServices on different HTTP endpoints
+- Content encoding (gzip,deflate) of request and response payloads
+- Automatic responses on OPTIONS (using a filter)
+- Automatic CORS request handling (using a filter)
+- API declaration for Swagger UI ([go-restful-openapi](https://github.com/emicklei/go-restful-openapi))
+- Panic recovery to produce HTTP 500, customizable using RecoverHandler(...)
+- Route errors produce HTTP 404/405/406/415 errors, customizable using ServiceErrorHandler(...)
+- Configurable (trace) logging
+- Customizable gzip/deflate readers and writers using CompressorProvider registration
+- Inject your own http.Handler using the `HttpMiddlewareHandlerToFilter` function
+
+## How to customize
+There are several hooks to customize the behavior of the go-restful package.
+
+- Router algorithm
+- Panic recovery
+- JSON decoder
+- Trace logging
+- Compression
+- Encoders for other serializers
+- Use [jsoniter](https://github.com/json-iterator/go) by building this package using a build tag, e.g. `go build -tags=jsoniter .`
+- Use the package variable `TrimRightSlashEnabled` (default true) to control the behavior of matching routes that end with a slash `/`
+

+/*
+Package restful , a lean package for creating REST-style WebServices without magic.
+
+WebServices and Routes
+
+A WebService has a collection of Route objects that dispatch incoming Http Requests to a function calls.
+Typically, a WebService has a root path (e.g. /users) and defines common MIME types for its routes.
+WebServices must be added to a container (see below) in order to handler Http requests from a server.
+
+A Route is defined by a HTTP method, an URL path and (optionally) the MIME types it consumes (Content-Type) and produces (Accept).
+This package has the logic to find the best matching Route and if found, call its Function.
+
+ ws := new(restful.WebService)
+ ws.
+ Path("/users").
+ Consumes(restful.MIME_JSON, restful.MIME_XML).
+ Produces(restful.MIME_JSON, restful.MIME_XML)
+
+ ws.Route(ws.GET("/{user-id}").To(u.findUser)) // u is a UserResource
+
+ ...
+
+ // GET http://localhost:8080/users/1
+ func (u UserResource) findUser(request *restful.Request, response *restful.Response) {
+ id := request.PathParameter("user-id")
+ ...
+ }
+
+The (*Request, *Response) arguments provide functions for reading information from the request and writing information back to the response.
+
+See the example https://github.com/emicklei/go-restful/blob/v3/examples/user-resource/restful-user-resource.go with a full implementation.
+
+Regular expression matching Routes
+
+A Route parameter can be specified using the format "uri/{var[:regexp]}" or the special version "uri/{var:*}" for matching the tail of the path.
+For example, /persons/{name:[A-Z][A-Z]} can be used to restrict values for the parameter "name" to only contain capital alphabetic characters.
+Regular expressions must use the standard Go syntax as described in the regexp package. (https://code.google.com/p/re2/wiki/Syntax)
+This feature requires the use of a CurlyRouter.
+
+Containers
+
+A Container holds a collection of WebServices, Filters and a http.ServeMux for multiplexing http requests.
+Using the statements "restful.Add(...) and restful.Filter(...)" will register WebServices and Filters to the Default Container.
+The Default container of go-restful uses the http.DefaultServeMux.
+You can create your own Container and create a new http.Server for that particular container.
+
+ container := restful.NewContainer()
+ server := &http.Server{Addr: ":8081", Handler: container}
+
+Filters
+
+A filter dynamically intercepts requests and responses to transform or use the information contained in the requests or responses.
+You can use filters to perform generic logging, measurement, authentication, redirect, set response headers etc.
+In the restful package there are three hooks into the request,response flow where filters can be added.
+Each filter must define a FilterFunction:
+
+ func (req *restful.Request, resp *restful.Response, chain *restful.FilterChain)
+
+Use the following statement to pass the request,response pair to the next filter or RouteFunction
+
+ chain.ProcessFilter(req, resp)
+
+Container Filters
+
+These are processed before any registered WebService.
+
+ // install a (global) filter for the default container (processed before any webservice)
+ restful.Filter(globalLogging)
+
+WebService Filters
+
+These are processed before any Route of a WebService.
+
+ // install a webservice filter (processed before any route)
+ ws.Filter(webserviceLogging).Filter(measureTime)
+
+
+Route Filters
+
+These are processed before calling the function associated with the Route.
+
+ // install 2 chained route filters (processed before calling findUser)
+ ws.Route(ws.GET("/{user-id}").Filter(routeLogging).Filter(NewCountFilter().routeCounter).To(findUser))
+
+See the example https://github.com/emicklei/go-restful/blob/v3/examples/filters/restful-filters.go with full implementations.
+
+Response Encoding
+
+Two encodings are supported: gzip and deflate. To enable this for all responses:
+
+ restful.DefaultContainer.EnableContentEncoding(true)
+
+If a Http request includes the Accept-Encoding header then the response content will be compressed using the specified encoding.
+Alternatively, you can create a Filter that performs the encoding and install it per WebService or Route.
+
+See the example https://github.com/emicklei/go-restful/blob/v3/examples/encoding/restful-encoding-filter.go
+
+OPTIONS support
+
+By installing a pre-defined container filter, your Webservice(s) can respond to the OPTIONS Http request.
+
+ Filter(OPTIONSFilter())
+
+CORS
+
+By installing the filter of a CrossOriginResourceSharing (CORS), your WebService(s) can handle CORS requests.
+
+ cors := CrossOriginResourceSharing{ExposeHeaders: []string{"X-My-Header"}, CookiesAllowed: false, Container: DefaultContainer}
+ Filter(cors.Filter)
+
+Error Handling
+
+Unexpected things happen. If a request cannot be processed because of a failure, your service needs to tell via the response what happened and why.
+For this reason HTTP status codes exist and it is important to use the correct code in every exceptional situation.
+
+ 400: Bad Request
+
+If path or query parameters are not valid (content or type) then use http.StatusBadRequest.
+
+ 404: Not Found
+
+Despite a valid URI, the resource requested may not be available
+
+ 500: Internal Server Error
+
+If the application logic could not process the request (or write the response) then use http.StatusInternalServerError.
+
+ 405: Method Not Allowed
+
+The request has a valid URL but the method (GET,PUT,POST,...) is not allowed.
+
+ 406: Not Acceptable
+
+The request does not have or has an unknown Accept Header set for this operation.
+
+ 415: Unsupported Media Type
+
+The request does not have or has an unknown Content-Type Header set for this operation.
+
+ServiceError
+
+In addition to setting the correct (error) Http status code, you can choose to write a ServiceError message on the response.
+
+Performance options
+
+This package has several options that affect the performance of your service. It is important to understand them and how you can change it.
+
+ restful.DefaultContainer.DoNotRecover(false)
+
+DoNotRecover controls whether panics will be caught to return HTTP 500.
+If set to false, the container will recover from panics.
+Default value is true
+
+ restful.SetCompressorProvider(NewBoundedCachedCompressors(20, 20))
+
+If content encoding is enabled then the default strategy for getting new gzip/zlib writers and readers is to use a sync.Pool.
+Because writers are expensive structures, performance is even more improved when using a preloaded cache. You can also inject your own implementation.
+
+Trouble shooting
+
+This package has the means to produce detail logging of the complete Http request matching process and filter invocation.
+Enabling this feature requires you to set an implementation of restful.StdLogger (e.g. log.Logger) instance such as:
+
+ restful.TraceLogger(log.New(os.Stdout, "[restful] ", log.LstdFlags|log.Lshortfile))
+
+Logging
+
+The restful.SetLogger() method allows you to override the logger used by the package. By default restful
+uses the standard library `log` package and logs to stdout. Different logging packages are supported as
+long as they conform to `StdLogger` interface defined in the `log` sub-package, writing an adapter for your
+preferred package is simple.

+// Unmarshal parses the JSON-encoded data and stores the result
+// in the value pointed to by v. If v is nil or not a pointer,
+// Unmarshal returns an InvalidUnmarshalError.
+//
+// Unmarshal uses the inverse of the encodings that
+// Marshal uses, allocating maps, slices, and pointers as necessary,
+// with the following additional rules:
+//
+// To unmarshal JSON into a pointer, Unmarshal first handles the case of
+// the JSON being the JSON literal null. In that case, Unmarshal sets
+// the pointer to nil. Otherwise, Unmarshal unmarshals the JSON into
+// the value pointed at by the pointer. If the pointer is nil, Unmarshal
+// allocates a new value for it to point to.
+//
+// To unmarshal JSON into a value implementing the Unmarshaler interface,
+// Unmarshal calls that value's UnmarshalJSON method, including
+// when the input is a JSON null.
+// Otherwise, if the value implements encoding.TextUnmarshaler
+// and the input is a JSON quoted string, Unmarshal calls that value's
+// UnmarshalText method with the unquoted form of the string.
+//
+// To unmarshal JSON into a struct, Unmarshal matches incoming object
+// keys to the keys used by Marshal (either the struct field name or its tag),
+// preferring an exact match but also accepting a case-insensitive match. By
+// default, object keys which don't have a corresponding struct field are
+// ignored (see Decoder.DisallowUnknownFields for an alternative).
+//
+// To unmarshal JSON into an interface value,
+// Unmarshal stores one of these in the interface value:
+//
+// bool, for JSON booleans
+// float64, for JSON numbers
+// string, for JSON strings
+// []interface{}, for JSON arrays
+// map[string]interface{}, for JSON objects
+// nil for JSON null
+//
+// To unmarshal a JSON array into a slice, Unmarshal resets the slice length
+// to zero and then appends each element to the slice.
+// As a special case, to unmarshal an empty JSON array into a slice,
+// Unmarshal replaces the slice with a new empty slice.
+//
+// To unmarshal a JSON array into a Go array, Unmarshal decodes
+// JSON array elements into corresponding Go array elements.
+// If the Go array is smaller than the JSON array,
+// the additional JSON array elements are discarded.
+// If the JSON array is smaller than the Go array,
+// the additional Go array elements are set to zero values.
+//
+// To unmarshal a JSON object into a map, Unmarshal first establishes a map to
+// use. If the map is nil, Unmarshal allocates a new map. Otherwise Unmarshal
+// reuses the existing map, keeping existing entries. Unmarshal then stores
+// key-value pairs from the JSON object into the map. The map's key type must
+// either be any string type, an integer, implement json.Unmarshaler, or
+// implement encoding.TextUnmarshaler.
+//
+// If the JSON-encoded data contain a syntax error, Unmarshal returns a SyntaxError.
+//
+// If a JSON value is not appropriate for a given target type,
+// or if a JSON number overflows the target type, Unmarshal
+// skips that field and completes the unmarshaling as best it can.
+// If no more serious errors are encountered, Unmarshal returns
+// an UnmarshalTypeError describing the earliest such error. In any
+// case, it's not guaranteed that all the remaining fields following
+// the problematic one will be unmarshaled into the target object.
+//
+// The JSON null value unmarshals into an interface, map, pointer, or slice
+// by setting that Go value to nil. Because null is often used in JSON to mean
+// “not present,” unmarshaling a JSON null into any other Go type has no effect
+// on the value and produces no error.
+//
+// When unmarshaling quoted strings, invalid UTF-8 or
+// invalid UTF-16 surrogate pairs are not treated as an error.
+// Instead, they are replaced by the Unicode replacement
+// character U+FFFD.

+// its MarshalText method and encodes the result as a JSON string.
+// The nil pointer exception is not strictly necessary
+// but mimics a similar, necessary exception in the behavior of
+// UnmarshalJSON.
+//
+// Otherwise, Marshal uses the following type-dependent default encodings:
+//
+// Boolean values encode as JSON booleans.
+//
+// Floating point, integer, and Number values encode as JSON numbers.

+// String values encode as JSON strings coerced to valid UTF-8,
