Expand description
Create a MakeService
from a function.
Example
use std::convert::Infallible;
use hyper::{Body, Request, Response, Server};
use hyper::server::conn::AddrStream;
use hyper::service::{make_service_fn, service_fn};
let addr = ([127, 0, 0, 1], 3000).into();
let make_svc = make_service_fn(|socket: &AddrStream| {
let remote_addr = socket.remote_addr();
async move {
Ok::<_, Infallible>(service_fn(move |_: Request<Body>| async move {
Ok::<_, Infallible>(
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...
if let Err(e) = server.await {
eprintln!("server error: {}", e);
}
