async-net

Async networking primitives for TCP/UDP/Unix communication.

This crate is an async version of std::net and std::os::unix::net.

Implementation

This crate uses async-io for async I/O and blocking for DNS lookups.

Examples

A simple UDP server that echoes messages back to the sender:

use async_net::UdpSocket;

# blocking::block_on(async {
let socket = UdpSocket::bind("127.0.0.1:8080").await?;
let mut buf = vec![0u8; 1024];

loop {
    let (n, peer) = socket.recv_from(&mut buf).await?;
    socket.send_to(&buf[..n], &peer).await?;
}
# std::io::Result::Ok(()) });
