tokio-splice
在 tokio-rs 中实现了基于 splice(2) 的双向数据传输。类似于 tokio::io::copy_bidirectional。
API
示例
以下代码实现了一个 TCP 代理，将端口 8989 上的流量转发到 example.com。
use std::io::Result;
use tokio::net::{TcpListener, TcpStream};
use tokio_splice::zero_copy_bidirectional;
async fn forwarding(mut stream1: TcpStream) -> Result<()> {
let mut stream2 = TcpStream::connect("93.184.216.34:80").await?;
zero_copy_bidirectional(&mut stream1, &mut stream2).await?;
Ok(())
}
async fn serve() -> Result<()> {
let listener = TcpListener::bind("127.0.0.1:8989").await?;
loop {
let (conn, addr) = listener.accept().await?;
println!("process incoming connection from {addr}");
tokio::spawn(forwarding(conn));
}
}
#[tokio::main(flavor = "current_thread")]
async fn main() -> Result<()> {
println!("PID is {}", std::process::id());
tokio::select! {
res = serve() => {
if let Err(err) = res {
println!("serve failed {err}");
}
}
_ = tokio::signal::ctrl_c() => {
println!("shutting down");
}
}
Ok(())
}
