Rust UnixStream.connect_addr用法及代碼示例

#![feature(unix_socket_abstract)]
use std::os::unix::net::{UnixListener, UnixStream};

fn main() -> std::io::Result<()> {
    let listener = UnixListener::bind("/path/to/the/socket")?;
    let addr = listener.local_addr()?;

    let sock = match UnixStream::connect_addr(&addr) {
        Ok(sock) => sock,
        Err(e) => {
            println!("Couldn't connect: {:?}", e);
            return Err(e)
        }
    };
    Ok(())
}
