pub struct UnixDatagram(_);
A Unix datagram socket.
use std::os::unix::net::UnixDatagram;
fn main() -> std::io::Result<()> {
let socket = UnixDatagram::bind("/path/to/my/socket")?;
socket.send_to(b"hello world", "/path/to/other/socket")?;
let mut buf = [0; 100];
let (count, address) = socket.recv_from(&mut buf)?;
println!("socket {:?} sent {:?}", address, &buf[..count]);
Ok(())
}impl UnixDatagram[src]
pub fn bind<P: AsRef<Path>>(path: P) -> Result<UnixDatagram>[src]
Creates a Unix datagram socket bound to the given path.
use std::os::unix::net::UnixDatagram;
let sock = match UnixDatagram::bind("/path/to/the/socket") {
Ok(sock) => sock,
Err(e) => {
println!("Couldn't bind: {:?}", e);
return
}
};pub fn unbound() -> Result<UnixDatagram>[src]
Creates a Unix Datagram socket which is not bound to any address.
use std::os::unix::net::UnixDatagram;
let sock = match UnixDatagram::unbound() {
Ok(sock) => sock,
Err(e) => {
println!("Couldn't unbound: {:?}", e);
return
}
};pub fn pair() -> Result<(UnixDatagram, UnixDatagram)>[src]
Creates an unnamed pair of connected sockets.
Returns two UnixDatagramss which are connected to each other.
use std::os::unix::net::UnixDatagram;
let (sock1, sock2) = match UnixDatagram::pair() {
Ok((sock1, sock2)) => (sock1, sock2),
Err(e) => {
println!("Couldn't unbound: {:?}", e);
return
}
};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.
use std::os::unix::net::UnixDatagram;
fn main() -> std::io::Result<()> {
let sock = UnixDatagram::unbound()?;
match sock.connect("/path/to/the/socket") {
Ok(sock) => sock,
Err(e) => {
println!("Couldn't connect: {:?}", e);
return Err(e)
}
};
Ok(())
}pub fn try_clone(&self) -> Result<UnixDatagram>[src]
Creates a new independently owned handle to the underlying socket.
The returned UnixDatagram 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 side will affect the other.
use std::os::unix::net::UnixDatagram;
fn main() -> std::io::Result<()> {

Ok(())
}pub fn local_addr(&self) -> Result<SocketAddr>[src]
Returns the address of this socket.

fn main() -> std::io::Result<()> {
let sock = UnixDatagram::bind("/path/to/the/socket")?;
let addr = sock.local_addr().expect("Couldn't get local address");
Ok(())
}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.
use std::os::unix::net::UnixDatagram;
fn main() -> std::io::Result<()> {
let sock = UnixDatagram::unbound()?;
sock.connect("/path/to/the/socket")?;
let addr = sock.peer_addr().expect("Couldn't get peer address");
Ok(())
}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.
use std::os::unix::net::UnixDatagram;
fn main() -> std::io::Result<()> {
let sock = UnixDatagram::unbound()?;
let mut buf = vec![0; 10];
let (size, sender) = sock.recv_from(buf.as_mut_slice())?;
println!("received {} bytes from {:?}", size, sender);
Ok(())
}pub fn recv(&self, buf: &mut [u8]) -> Result<usize>[src]
Receives data from the socket.
On success, returns the number of bytes read.
use std::os::unix::net::UnixDatagram;
fn main() -> std::io::Result<()> {
let sock = UnixDatagram::bind("/path/to/the/socket")?;
let mut buf = vec![0; 10];
sock.recv(buf.as_mut_slice()).expect("recv function failed");
Ok(())
}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.
use std::os::unix::net::UnixDatagram;
fn main() -> std::io::Result<()> {
let sock = UnixDatagram::unbound()?;
sock.send_to(b"omelette au fromage", "/some/sock").expect("send_to function failed");
Ok(())
}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.
use std::os::unix::net::UnixDatagram;
fn main() -> std::io::Result<()> {
let sock = UnixDatagram::unbound()?;
sock.connect("/some/sock").expect("Couldn't connect");
sock.send(b"omelette au fromage").expect("send_to function failed");
Ok(())
}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. An Err is returned if the zero Duration is passed to this method.
use std::os::unix::net::UnixDatagram;

fn main() -> std::io::Result<()> {
let sock = UnixDatagram::unbound()?;
sock.set_read_timeout(Some(Duration::new(1, 0)))

let err = result.unwrap_err();
assert_eq!(err.kind(), io::ErrorKind::InvalidInput);
Ok(())
}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. An Err is returned if the zero Duration is passed to this method.
use std::os::unix::net::UnixDatagram;
use std::time::Duration;

Returns the read timeout of this socket.

Returns the write timeout of this socket.

Ok(())
}pub fn set_nonblocking(&self, nonblocking: bool) -> Result<()>[src]
Moves the socket into or out of nonblocking mode.

let sock = UnixDatagram::unbound()?;
sock.set_nonblocking(true).expect("set_nonblocking function failed");
Ok(())
}pub fn take_error(&self) -> Result<Option<Error>>[src]
Returns the value of the SO_ERROR option.

if let Ok(Some(err)) = sock.take_error() {
println!("Got error: {:?}", err);
}
Ok(())
}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).
use std::os::unix::net::UnixDatagram;
use std::net::Shutdown;
fn main() -> std::io::Result<()> {
