[][src]Module hyper::server

This is supported on crate feature server only.

HTTP Server

A Server is created to listen on a port, parse HTTP requests, and hand them off to a Service.

There are two levels of APIs provide for constructing HTTP servers:

  • The higher-level Server type.
  • The lower-level conn module.


The Server is main way to start listening for HTTP requests. It wraps a listener with a MakeService, and then should be executed to start serving requests.

Server accepts connections in both HTTP1 and HTTP2 by default.


use std::convert::Infallible;
use std::net::SocketAddr;
use hyper::{Body, Request, Response, Server};
use hyper::service::{make_service_fn, service_fn};

async fn handle(_req: Request<Body>) -> Result<Response<Body>, Infallible> {
    Ok(Response::new(Body::from("Hello World")))

async fn main() {
    // Construct our SocketAddr to listen on...
    let addr = SocketAddr::from(([127, 0, 0, 1], 3000));

    // And a MakeService to handle each connection...
    let make_service = make_service_fn(|_conn| async {
        Ok::<_, Infallible>(service_fn(handle))

    // Then bind and serve...
    let server = Server::bind(&addr).serve(make_service);

    // And run forever...
    if let Err(e) = server.await {
        eprintln!("server error: {}", e);
