Struct std::os::unix::net::Incoming

pub struct Incoming<'a> { /* fields omitted */ }

This is supported on Unix only.

It will never return None.

Examples

use std::thread;
use std::os::unix::net::{UnixStream, UnixListener};

fn handle_client(stream: UnixStream) {
    // ...
}

let listener = UnixListener::bind("/path/to/the/socket").unwrap();

for stream in listener.incoming() {
    match stream {
        Ok(stream) => {
            thread::spawn(|| handle_client(stream));
        }
        Err(err) => {
            break;
