Crate udp_server 

udp_server

High-performance async UDP server framework built on Tokio.

Design

The framework binds multiple UDP sockets to the same address (leveraging SO_REUSEPORT on Unix for kernel-level load balancing). Each remote address is abstracted as a [UdpPeer] with its own send/receive channel and a dedicated handler task. Users provide a single async closure — the framework handles socket lifecycle, peer creation/removal, and idle timeout cleanup.

Quick Example

use udp_server::prelude::UdpServer;

UdpServer::new("0.0.0.0:20001", |peer, mut reader, _| async move {
    while let Some(Ok(data)) = reader.recv().await {
        peer.send(&data).await?;
    }
    Ok(())
})?
.set_peer_timeout_sec(20)
.start(())
.await?;

Modules

prelude

Convenience re-exports so users can write use udp_server::prelude::*.
