use tokio::net::{TcpListener, TcpStream};

use async_stream::try_stream;
use futures_core::stream::Stream;

use std::io;

fn bind_and_accept(addr: SocketAddr)
    -> impl Stream<Item = io::Result<TcpStream>>
{
    try_stream! {
        let mut listener = TcpListener::bind(addr).await?;

        loop {
            let (stream, addr) = listener.accept().await?;
            println!("received on {:?}", addr);
            yield stream;
