Struct async_std::os::unix::net::UnixListener

pub struct UnixListener { /* private fields */ }

Available on Unix only.

A Unix domain socket server, listening for connections.

After creating a UnixListener by binding it to a socket address, it listens for incoming connections. These can be accepted by awaiting elements from the async stream of incoming connections.

The socket will be closed when the value is dropped.

This type is an async version of std::os::unix::net::UnixListener.

Examples

use async_std::os::unix::net::UnixListener;
use async_std::prelude::*;

let listener = UnixListener::bind("/tmp/socket").await?;
let mut incoming = listener.incoming();

while let Some(stream) = incoming.next().await {
    let mut stream = stream?;
    stream.write_all(b"hello world").await?;
}

Implementations

impl UnixListener

pub async fn bind<P: AsRef<Path>>(path: P) -> Result<UnixListener>

Creates a Unix datagram listener bound to the given path.

Examples

use async_std::os::unix::net::UnixListener;

let listener = UnixListener::bind("/tmp/socket").await?;

pub async fn accept(&self) -> Result<(UnixStream, SocketAddr)>

Accepts a new incoming connection to this listener.

When a connection is established, the corresponding stream and address will be returned.

Examples

use async_std::os::unix::net::UnixListener;

let listener = UnixListener::bind("/tmp/socket").await?;
let (socket, addr) = listener.accept().await?;

pub fn incoming(&self) -> Incoming<'_>

Returns a stream of incoming connections.

Iterating over this stream is equivalent to calling accept in a loop. The stream of connections is infinite, i.e awaiting the next connection will never result in None.

Examples

use async_std::os::unix::net::UnixListener;
use async_std::prelude::*;

let listener = UnixListener::bind("/tmp/socket").await?;
let mut incoming = listener.incoming();

while let Some(stream) = incoming.next().await {
    let mut stream = stream?;
    stream.write_all(b"hello world").await?;
}

pub fn local_addr(&self) -> Result<SocketAddr>

Returns the local socket address of this listener.

Examples

use async_std::os::unix::net::UnixListener;

let listener = UnixListener::bind("/tmp/socket").await?;
let addr = listener.local_addr()?;
