A simple enum that supports tokio::io::AsyncRead and tokio::io::AsyncWrite on TCP as well as Unix sockets. * *

• Example

• A simple TCP echo server:
• use async_stream_connection::Listener;
• use tokio::io::{AsyncReadExt, AsyncWriteExt};
• #[tokio::main(flavor = "current_thread")]
• async fn main() -> Result<(), Box> {

•  let listener = Listener::bind(&"127.0.0.1:8080".parse()?).await?;
  

•  loop {
  

•      let (mut socket, _) = listener.accept().await?;
  

•      tokio::spawn(async move {
  

•          let mut buf = [0; 1024];
  

•          // In a loop, read data from the socket and write the data back.
  

•          loop {
  

•              let n = match socket.read(&mut buf).await {
  

•                  // socket closed
  

•                  Ok(n) if n == 0 => return,
  

•                  Ok(n) => n,
  

•                  Err(e) => {
  

•                      eprintln!("failed to read from socket; err = {:?}", e);
  

•                      return;
  

•                  }
  

•              };
  

•              // Write the data back
  

•              if let Err(e) = socket.write_all(&buf[0..n]).await {
  

•                  eprintln!("failed to write to socket; err = {:?}", e);
  

•                  return;
  

•              }
  

•          }
  

•      });
  

•  }
