Expand description

A datagram protocol run by a server: one per UDP listener, called on that listener’s thread, so it needs no locks of its own. Budgets and the amplification guard apply before it sees a datagram and on every reply.

use std::net::SocketAddr;
use net_io::{UdpContext, UdpSession};
struct Echo;
impl UdpSession for Echo {
    fn on_datagram(&mut self, cx: &mut UdpContext<'_>, from: SocketAddr, bytes: &[u8]) {
        let _ = cx.send_to(bytes, from);
    }
}

Required Methods§
