Struct LoopbackSocket

pub struct LoopbackSocket { /* private fields */ }

An instance of AsyncDatagramSocket that implements a simple loopback interface, where all packets that are sent are looped back to the input.

Implementations

impl LoopbackSocket

pub fn new() -> LoopbackSocket

Creates a new instance of LoopbackSocket.

Trait Implementations

impl AsyncRecvFrom for LoopbackSocket

fn poll_recv_from( self: Pin<&Self>, cx: &mut Context<'_>, buf: &mut [u8], ) -> Poll<Result<(usize, Self::SocketAddr, Option<Self::SocketAddr>), Self::Error>>

A non-blocking, poll_* version of std::net::UdpSocket::recv_from that can optionally provide the destination (local) SocketAddr.

fn next_recv_from<'a, 'b>( &'a self, buf: &'b mut [u8], ) -> NextRecvFromFuture<'a, 'b, Self>

Returns a future that uses poll_recv_from.

impl AsyncSendTo for LoopbackSocket

fn poll_send_to<B>( self: Pin<&Self>, cx: &mut Context<'_>, buf: &[u8], addr: B, ) -> Poll<Result<usize, Self::Error>>

where B: ToSocketAddrs<SocketAddr = Self::SocketAddr, Error = Self::Error>,

A non-blocking, poll_* version of std::net::UdpSocket::send_to.

fn next_send_to<'a, 'b, B>( &'a self, buf: &'b [u8], addr: B, ) -> NextSendToFuture<'a, 'b, Self>

where B: ToSocketAddrs<SocketAddr = Self::SocketAddr, Error = Self::Error>,

Returns a future that uses AsyncSendTo::poll_send_to.

fn send_to<B>(&self, buf: &[u8], addr: B) -> Result<usize, Self::Error>

where B: ToSocketAddrs<SocketAddr = Self::SocketAddr, Error = Self::Error>,

A synchronous version of AsyncSendTo::poll_send_to. If this isn’t overridden by the trait’s implementation, the default version will call poll_send_to() and panics if it returns Poll::Pending.

impl DatagramSocketTypes for LoopbackSocket

type SocketAddr = LoopbackSocketAddr

The “SocketAddr” type used by this “socket”. Typically std::net::SocketAddr.

type Error = Error

The error type for errors emitted from this socket. Typically std::io::Error.

fn local_addr(&self) -> Result<Self::SocketAddr, Self::Error>

Returns the local SocketAddr of this “socket”.

fn lookup_host( host: &str, _port: u16, ) -> Result<IntoIter<Self::SocketAddr>, Self::Error>

where Self: Sized,

Performs a blocking hostname lookup.

impl Debug for LoopbackSocket

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl MulticastSocket for LoopbackSocket

type IpAddr = String

The “address” type for this socket.

fn join_multicast<A>(&self, _addr: A) -> Result<(), Self::Error>

where A: Into<Self::IpAddr>,

Attempts to join the given multicast group.

fn leave_multicast<A>(&self, _addr: A) -> Result<(), Self::Error>

where A: Into<Self::IpAddr>,

Attempts to leave the given multicast group.
