Struct tokio_shared_udp_socket::SharedUdpSocket

pub struct SharedUdpSocket { /* fields omitted */ }

A UDP socket that can easily be shared amongst a bunch of different tasks.

SharedUdpSocket can be used as a Stream to receive incoming packets along with their addresses. The with_address method can be used to divert packets from a given address to a seperate Stream so they can be processed seperately.

Methods

impl SharedUdpSocket

fn share(socket: UdpSocket) -> SharedUdpSocket

Create a new SharedUdpSocket from a UdpSocket.

fn with_address(&self, addr: SocketAddr) -> WithAddress

Creates a WithAddress object which receives all packets that arrive from the given address. WithAddress can also be used as a Sink to send packets. When the WithAddress is dropped, any further or unprocessed packets arriving from the given address will instead be received through the SharedUdpSocket.
