pub struct UnixListener(/* private fields */);
Expand description
A structure representing a Unix domain socket server.
§Examples
use std::thread;
use std::os::unix::net::{UnixStream, UnixListener};
fn handle_client(stream: UnixStream) {
// ...
}
fn main() -> std::io::Result<()> {
let listener = UnixListener::bind("/path/to/the/socket")?;
// accept connections and process them, spawning a new thread for each one
for stream in listener.incoming() {
match stream {
Ok(stream) => {
/* connection succeeded */
thread::spawn(|| handle_client(stream));
}
Err(err) => {
/* connection failed */
break;
}
}
}
Ok(())

impl UnixListener
1.70.0 · sourcepub fn bind_addr(socket_addr: &SocketAddr) -> Result<UnixListener>
pub fn bind_addr(socket_addr: &SocketAddr) -> Result<UnixListener>
Creates a new UnixListener
bound to the specified socket address
.
§Examples
use std::os::unix::net::{UnixListener};
fn main() -> std::io::Result<()> {
let listener1 = UnixListener::bind("path/to/socket")?;
let addr = listener1.local_addr()?;
let listener2 = match UnixListener::bind_addr(&addr) {
Ok(sock) => sock,
Err(err) => {
println!("Couldn't bind: {err:?}");
return Err(err);
}
};
Ok(())
}
Runsourcepub fn accept(&self) -> Result<(UnixStream, SocketAddr)>
pub fn accept(&self) -> Result<(UnixStream, SocketAddr)>
Accepts a new incoming connection to this listener.
This function will block the calling thread until a new Unix connection
is established. When established, the corresponding UnixStream
and
the remote peer’s address will be returned.
§Examples
use std::os::unix::net::UnixListener;
fn main() -> std::io::Result<()> {
let listener = UnixListener::bind("/path/to/the/socket")?;
match listener.accept() {
Ok((socket, addr)) => println!("Got a client: {addr:?}"),
Err(e) => println!("accept function failed: {e:?}"),
}
Ok(())
}
Runsourcepub fn try_clone(&self) -> Result<UnixListener>
pub fn try_clone(&self) -> Result<UnixListener>
Creates a new independently owned handle to the underlying socket.
The returned UnixListener
is a reference to the same socket that this
object references. Both handles can be used to accept incoming
connections and options set on one listener will affect the other.
§Examples
use std::os::unix::net::UnixListener;
fn main() -> std::io::Result<()> {
let listener = UnixListener::bind("/path/to/the/socket")?;
let listener_copy = listener.try_clone().expect("try_clone failed");
Ok(())
}
Runsourcepub fn local_addr(&self) -> Result<SocketAddr>
pub fn local_addr(&self) -> Result<SocketAddr>
sourcepub fn set_nonblocking(&self, nonblocking: bool) -> Result<()>
pub fn set_nonblocking(&self, nonblocking: bool) -> Result<()>
Moves the socket into or out of nonblocking mode.
This will result in the accept
operation becoming nonblocking,
i.e., immediately returning from their calls. If the IO operation is
successful, Ok
is returned and no further action is required. If the
IO operation could not be completed and needs to be retried, an error
with kind io::ErrorKind::WouldBlock
is returned.
§Examples
use std::os::unix::net::UnixListener;
fn main() -> std::io::Result<()> {
let listener = UnixListener::bind("/path/to/the/socket")?;
listener.set_nonblocking(true).expect("Couldn't set non blocking");
Ok(())
}
Runsourcepub fn take_error(&self) -> Result<Option<Error>>
pub fn take_error(&self) -> Result<Option<Error>>
Returns the value of the SO_ERROR
option.
§Examples
use std::os::unix::net::UnixListener;
fn main() -> std::io::Result<()> {
let listener = UnixListener::bind("/tmp/sock")?;
if let Ok(Some(err)) = listener.take_error() {
println!("Got error: {err:?}");
}
Ok(())
}
Run§Platform specific
On Redox this always returns None
.
sourcepub fn incoming(&self) -> Incoming<'_> ⓘ
pub fn incoming(&self) -> Incoming<'_> ⓘ
Returns an iterator over incoming connections.
The iterator will never return None
and will also not yield the
peer’s SocketAddr
structure.
§Examples
use std::thread;
use std::os::unix::net::{UnixStream, UnixListener};
fn handle_client(stream: UnixStream) {
// ...
}
fn main() -> std::io::Result<()> {
let listener = UnixListener::bind("/path/to/the/socket")?;
for stream in listener.incoming() {
match stream {
Ok(stream) => {
thread::spawn(|| handle_client(stream));
}
Err(err) => {
break;
}
}
}
Ok(())
}
