Expand description

Create a MakeService from a function.

Example

use std::net::TcpStream;
use hyper::{Body, Request, Response, Server};
use hyper::rt::{self, Future};
use hyper::server::conn::AddrStream;
use hyper::service::{make_service_fn, service_fn_ok};

let addr = ([127, 0, 0, 1], 3000).into();

let make_svc = make_service_fn(|socket: &AddrStream| {
    let remote_addr = socket.remote_addr();
    service_fn_ok(move |_: Request<Body>| {
        Response::new(Body::from(format!("Hello, {}", remote_addr)))
    })
});

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

// Finally, spawn `server` onto an Executor...
rt::run(server.map_err(|e| {
    eprintln!("server error: {}", e);
}));
