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

fn main() -> std::io::Result<()> {
    let sock1 = UnixDatagram::bind("path/to/socket")?;
    let addr = sock1.local_addr()?;

    let sock2 = match UnixDatagram::bind_addr(&addr) {
        Ok(sock) => sock,
        Err(err) => {
            println!("Couldn't bind: {:?}", err);
            return Err(err);
        }
    };
