source · [−]
pub trait ServiceBuilderExt<L>: Sealed<L> + Sized {

Expand description

Extension trait that adds methods to tower::ServiceBuilder for adding middleware from tower-http.

Example

use http::{Request, Response, header::HeaderName};
use hyper::Body;
use std::{time::Duration, convert::Infallible};
use tower::{ServiceBuilder, ServiceExt, Service};
use tower_http::ServiceBuilderExt;

async fn handle(request: Request<Body>) -> Result<Response<Body>, Infallible> {
    Ok(Response::new(Body::empty()))
}

let service = ServiceBuilder::new()
    // Methods from tower
    .timeout(Duration::from_secs(30))
    // Methods from tower-http
    .trace_for_http()
    .compression()
    .propagate_header(HeaderName::from_static("x-request-id"))
    .service_fn(handle);
