Module timeout

Middleware that applies a timeout to requests.

If the request does not complete within the specified timeout it will be aborted and a 408 Request Timeout response will be sent.

Differences from tower::timeout

tower’s Timeout middleware uses an error to signal timeout, i.e. it changes the error type to BoxError. For HTTP services that is rarely what you want as returning errors will terminate the connection without sending a response.

This middleware won’t change the error type and instead return a 408 Request Timeout response. That means if your service’s error type is Infallible it will still be Infallible after applying this middleware.

Example

use http::{Request, Response};
use http_body_util::Full;
use bytes::Bytes;
use std::{convert::Infallible, time::Duration};
use tower::ServiceBuilder;
use tower_http::timeout::TimeoutLayer;

async fn handle(_: Request<Full<Bytes>>) -> Result<Response<Full<Bytes>>, Infallible> {
    // ...
}

let svc = ServiceBuilder::new()
    // Timeout requests after 30 seconds
    .layer(TimeoutLayer::new(Duration::from_secs(30)))
    .service_fn(handle);
