Struct asio::ip::Udp

pub struct Udp {
    // some fields omitted
}

The User Datagram Protocol.

Examples

In this example, Creates a UDP server socket with resolving.

use std::io;
use asio::{IoService, Protocol};
use asio::ip::{Udp, UdpSocket, UdpEndpoint, UdpResolver, ResolverIter, Passive};

fn udp_bind(io: &IoService, it: ResolverIter<Udp>) -> io::Result<UdpSocket> {
    for (ep, _) in it {
        println!("{:?}", ep);
        if let Ok(soc) = UdpSocket::new(io, ep.protocol()) {
            if let Ok(_) = soc.bind(&ep) {
                return Ok(soc)
            }
        }
    }
    Err(io::Error::new(io::ErrorKind::Other, "Failed to bind"))
}

let io = IoService::new();
let re = UdpResolver::new(&io);
let sv = re.resolve((Passive, 12345))
           .and_then(|it| udp_bind(&io, it))
           .unwrap();
