Struct glommio::net::UnixDatagram [−][src]
pub struct UnixDatagram { /* fields omitted */ }
Expand description
A Unix Datagram Socket.
Implementations
Creates an unnamed pair of connected Unix Datagram sockets.
Examples
use glommio::{net::UnixDatagram, LocalExecutor};
let ex = LocalExecutor::default();
ex.run(async move {
let (mut p1, mut p2) = UnixDatagram::pair().unwrap();
let sz = p1.send(&[65u8; 1]).await.unwrap();
let mut buf = [0u8; 1];
let sz = p2.recv(&mut buf).await.unwrap();
})
Creates a Unix Datagram socket bound to the specified address.
Examples
use glommio::{net::UnixDatagram, LocalExecutor};
let ex = LocalExecutor::default();
ex.run(async move {
let listener = UnixDatagram::bind("/tmp/named_dgram").unwrap();
println!("Listening on {:?}", listener.local_addr().unwrap());
});
Creates a Unix Datagram socket which is not bound to any address.
Connects an unbounded Unix Datagram socket to a remote address, allowing
the send
and recv
methods to be used to send data and also
applies filters to only receive data from the specified address.
If addr yields multiple addresses, connect will be attempted with each of the addresses until the underlying OS function returns no error. Note that usually, a successful connect call does not specify that there is a remote server listening on the port, rather, such an error would only be detected after the first send. If the OS returns an error for each of the specified addresses, the error returned from the last connection attempt (the last address) is returned.
Examples
use glommio::{net::UnixDatagram, LocalExecutor};
let ex = LocalExecutor::default();
ex.run(async move {
let receiver = UnixDatagram::bind("/tmp/dgram").unwrap();
let sender = UnixDatagram::unbound().unwrap();
sender.connect("/tmp/dgram").await.unwrap();
});
Sets the buffer size used on the receive path
gets the buffer size used
Receives single datagram on the socket from the remote address to which it is connected, without removing the message from input queue. On success, returns the number of bytes peeked.
The function must be called with valid byte array buf of sufficient size to hold the message bytes. If a message is too long to fit in the supplied buffer, excess bytes may be discarded.
To use this function, connect
must have been called
Examples
use glommio::{net::UnixDatagram, LocalExecutor};
let ex = LocalExecutor::default();
ex.run(async move {
let receiver = UnixDatagram::bind("/tmp/dgram").unwrap();
let sender = UnixDatagram::unbound().unwrap();
sender.connect("/tmp/dgram").await.unwrap();
sender.send(&[1; 1]).await.unwrap();
let mut buf = vec![0; 32];
let sz = receiver.peek(&mut buf).await.unwrap();
assert_eq!(sz, 1);
})
Receives a single datagram message on the socket, without removing it from the queue. On success, returns the number of bytes read and the origin.
The function must be called with valid byte array buf of sufficient size to hold the message bytes. If a message is too long to fit in the supplied buffer, excess bytes may be discarded.
Returns the socket address of the remote peer this socket was connected to.
Returns the socket address of the local half of this Unix Datagram connection.
Receives a single datagram message on the socket from the remote address to which it is connected.
On success, returns the number of bytes read. The function must be called with valid byte array buf of sufficient size to hold the message bytes. If a message is too long to fit in the supplied buffer, excess bytes may be discarded.

must have been called

use glommio::{net::UnixDatagram, LocalExecutor};
let ex = LocalExecutor::default();
ex.run(async move {
let receiver = UnixDatagram::bind("/tmp/dgram").unwrap();
let sender = UnixDatagram::unbound().unwrap();
sender.connect("/tmp/dgram").await.unwrap();
sender.send(&[1; 1]).await.unwrap();
let mut buf = vec![0; 32];
let sz = receiver.recv(&mut buf).await.unwrap();
assert_eq!(sz, 1);

let mut buf = vec![0; 32];
let (sz, _addr) = receiver.recv_from(&mut buf).await.unwrap();
assert_eq!(sz, 1);
})
Sends data on the socket to the given address. On success, returns the number of bytes written.
Examples
use glommio::{net::UnixDatagram, LocalExecutor};
let ex = LocalExecutor::default();
ex.run(async move {
let sender = UnixDatagram::unbound().unwrap();
sender.send_to(&[1; 1], "/tmp/dgram").await.unwrap();
})
Sends data on the socket to the remote address to which it is connected.
UnixDatagram::connect
will connect this socket to a remote address.
This method will fail if the socket is not connected.
Examples
use glommio::{net::UnixDatagram, LocalExecutor};
let ex = LocalExecutor::default();
ex.run(async move {
let receiver = UnixDatagram::bind("/tmp/dgram").unwrap();
let sender = UnixDatagram::unbound().unwrap();
sender.connect("/tmp/dgram").await.unwrap();
sender.send(&[1; 1]).await.unwrap();
})
