+//! The native `thread` module for the [Rune Language].
+//!
+//! [Rune Language]: https://rune-rs.github.io
+//!
+//! ## Usage
+//!
+//! Add the following to your `Cargo.toml`:
+//!
+//! ```toml
+//! rune-modules = { version = "0.14.0", features = ["thread"] }
+//! ```
+//!
+//! Install it into your context:
+//!
+//! ```rust
+//! let mut context = rune::Context::with_default_modules()?;
+//! context.install(rune_modules::thread::module(true)?)?;
+//! # Ok::<_, rune::support::Error>(())
+//! ```
+//!
+//! Use it in Rune:
+//!
+//! ```rust,ignore
+//! use time::Duration;
+//!
+//! fn main() {
+//!     thread::sleep(Duration::from_seconds(3));
+//! }
+//! ```
+
+use crate::time::Duration;
+use rune::{ContextError, Module};
+use std::thread;
+
+/// Construct the `thread` module.
+pub fn module(_stdio: bool) -> Result<Module, ContextError> {
+    let mut module = Module::with_crate("thread")?;
+    module.function("sleep", sleep).build()?;
+    Ok(module)
+}
+
+/// Puts the current thread to sleep for at least the specified amount of time.
+fn sleep(duration: &Duration) {
+    thread::sleep(duration.into_std())
+}
