Rust UnixDatagram用法及代码示例

use std::os::unix::net::UnixDatagram;

fn main() -> std::io::Result<()> {
    let socket = UnixDatagram::bind("/path/to/my/socket")?;
    socket.send_to(b"hello world", "/path/to/other/socket")?;
    let mut buf = [0; 100];
    let (count, address) = socket.recv_from(&mut buf)?;
    println!("socket {:?} sent {:?}", address, &buf[..count]);
    Ok(())
}
