1//! Runtime components
2//!
3//! The traits and types within this module are used to allow plugging in
4//! runtime types. These include:
5//!
6//! - Executors
7//! - Timers
8//! - IO transports

17/// An executor of futures.
18///
19/// This trait allows Hyper to abstract over async runtimes. Implement this trait for your own type.
20///
21/// # Example
22///
23/// ```
24/// # use hyper::rt::Executor;
25/// # use std::future::Future;
26/// #[derive(Clone)]
27/// struct TokioExecutor;
28///
29/// impl<F> Executor<F> for TokioExecutor
30/// where
31/// F: Future + Send + 'static,
32/// F::Output: Send + 'static,
33/// {
34/// fn execute(&self, future: F) {
35/// tokio::spawn(future);
36/// }
37/// }
38/// ```
39pub trait Executor<Fut> {
40 /// Place the future into the executor to be run.
41 fn execute(&self, fut: Fut);
