An extension trait to support source address selection in std::net::UdpSocket

See module level documentation for more details.

Required Methods

fn bind_sas<A: ToSocketAddrs>(addr: A) -> Result<Self>

Creates a UDP socket from the given address.

The address type can be any implementor of ToSocketAddrs trait. See its documentation for concrete examples.

The new socket is configured with the IP_PKTINFO or IPV6_RECVPKTINFO option enabled.

Examples

use std::net::UdpSocket;
use udp_sas_async::UdpSas;

let socket = UdpSocket::bind_sas("127.0.0.1:34254").expect("couldn't bind to address");

fn send_sas( &self, buf: &[u8], target: &SocketAddr, local: &IpAddr ) -> Result<usize>

Sends a datagram to the given target address and use the local address as its source.

On success, returns the number of bytes written.

fn recv_sas(&self, buf: &mut [u8]) -> Result<(usize, SocketAddr, IpAddr)>

Receive a datagram

On success, returns a tuple (nb, source, local) containing the number of bytes read, the source socket address (peer address), and the destination ip address (local address).

Object Safety

This trait is not object safe.
