# 1.10.0[−][src]Struct std::os::unix::net::UnixListener

    pub struct UnixListener(_);

This is supported on Unix only.

A structure representing a Unix domain socket server.

# 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();

    // 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;
            }
        }
    }Run

## Methods

### `impl UnixListener`[src]

#### `pub fn bind<P: AsRef<Path>>(path: P) -> Result<UnixListener>`[src]

This is supported on Unix only.

Creates a new `UnixListener` bound to the specified socket.

# Examples

    use std::os::unix::net::UnixListener;

    let listener = match UnixListener::bind("/path/to/the/socket") {
        Ok(sock) => sock,
        Err(e) => {
            println!("Couldn't connect: {:?}", e);
            return
        }
    };Run

#### `pub fn accept(&self) -> Result<(UnixStream, SocketAddr)>`[src]

This is supported on Unix only.

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;

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

    match listener.accept() {
        Ok((socket, addr)) => println!("Got a client: {:?}", addr),
        Err(e) => println!("accept function failed: {:?}", e),
    }Run

#### `pub fn try_clone(&self) -> Result<UnixListener>`[src]

This is supported on Unix only.

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;

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

    let listener_copy = listener.try_clone().expect("try_clone failed");Run

#### `pub fn local_addr(&self) -> Result<SocketAddr>`[src]

This is supported on Unix only.

Returns the local socket address of this listener.

# Examples

    use std::os::unix::net::UnixListener;

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

    let addr = listener.local_addr().expect("Couldn't get local address");Run

#### `pub fn set_nonblocking(&self, nonblocking: bool) -> Result<()>`[src]

This is supported on Unix only.

Moves the socket into or out of nonblocking mode.

# Examples

    use std::os::unix::net::UnixListener;

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

    listener.set_nonblocking(true).expect("Couldn't set non blocking");Run

#### `pub fn take_error(&self) -> Result<Option<Error>>`[src]

This is supported on Unix only.

Returns the value of the `SO_ERROR` option.

# Examples

    use std::os::unix::net::UnixListener;

    let listener = UnixListener::bind("/tmp/sock").unwrap();

    if let Ok(Some(err)) = listener.take_error() {
        println!("Got error: {:?}", err);
    }Run

# Platform specific

On Redox this always returns `None`.

### Important traits for Incoming<'a>

`impl<'a> Iterator for Incoming<'a> type Item = Result<UnixStream>;`
`pub fn incoming<'a>(&'a self) -> Incoming<'a>`[src]

This is supported on Unix only.

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) {
        // ...
    }

    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;
            }
        }
    }Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
