Struct unix_socket::UnixDatagram[][src]

pub struct UnixDatagram { /* fields omitted */ }

A Unix datagram socket.

Examples

use unix_socket::UnixDatagram;

let socket = UnixDatagram::bind("/path/to/my/socket").unwrap();
socket.send_to(b"hello world", "/path/to/other/socket").unwrap();
let mut buf = [0; 100];
let (count, address) = socket.recv_from(&mut buf).unwrap();
println!("socket {:?} sent {:?}", address, &buf[..count]);

Implementations

impl UnixDatagram[src]

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

Creates a Unix datagram socket bound to the given path.

Linux provides, as a nonportable extension, a separate “abstract” address namespace as opposed to filesystem-based addressing. If path begins with a null byte, it will be interpreted as an “abstract” address. Otherwise, it will be interpreted as a “pathname” address, corresponding to a path on the filesystem.

pub fn unbound() -> Result<UnixDatagram>[src]

Creates a Unix Datagram socket which is not bound to any address.

pub fn pair() -> Result<(UnixDatagram, UnixDatagram)>[src]

Create an unnamed pair of connected sockets.

Returns two UnixDatagramss which are connected to each other.

pub fn connect<P: AsRef<Path>>(&self, path: P) -> Result<()>[src]

Connects the socket to the specified address.

The send method may be used to send data to the specified address. recv and recv_from will only receive data from that address.

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

Returns the address of this socket.

pub fn peer_addr(&self) -> Result<SocketAddr>[src]

Returns the address of this socket’s peer.

The connect method will connect the socket to a peer.

pub fn recv_from(&self, buf: &mut [u8]) -> Result<(usize, SocketAddr)>[src]

Receives data from the socket.

On success, returns the number of bytes read and the address from whence the data came.

pub fn recv(&self, buf: &mut [u8]) -> Result<usize>[src]

Receives data from the socket.

On success, returns the number of bytes read.

pub fn send_to<P: AsRef<Path>>(&self, buf: &[u8], path: P) -> Result<usize>[src]

Sends data on the socket to the specified address.

On success, returns the number of bytes written.

pub fn send(&self, buf: &[u8]) -> Result<usize>[src]

Sends data on the socket to the socket’s peer.

The peer address may be set by the connect method, and this method will return an error if the socket has not already been connected.

On success, returns the number of bytes written.

pub fn set_read_timeout(&self, timeout: Option<Duration>) -> Result<()>[src]

Sets the read timeout for the socket.

If the provided value is None, then recv and recv_from calls will block indefinitely. It is an error to pass the zero Duration to this method.

pub fn set_write_timeout(&self, timeout: Option<Duration>) -> Result<()>[src]

Sets the write timeout for the socket.

If the provided value is None, then send and send_to calls will block indefinitely. It is an error to pass the zero Duration to this method.

pub fn read_timeout(&self) -> Result<Option<Duration>>[src]

Returns the read timeout of this socket.

pub fn write_timeout(&self) -> Result<Option<Duration>>[src]

Returns the write timeout of this socket.

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

Moves the socket into or out of nonblocking mode.

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

Returns the value of the SO_ERROR option.

pub fn shutdown(&self, how: Shutdown) -> Result<()>[src]

Shut down the read, write, or both halves of this connection.

This function will cause all pending and future I/O calls on the specified portions to immediately return with an appropriate value (see the documentation of Shutdown).
