Available on crate features net and codec only.

A trait for a listener: TcpListener and UnixListener.

Required Associated Types

type Io: AsyncRead + AsyncWrite

The stream’s type of this listener.

type Addr

The socket address type of this listener.

Required Methods

fn poll_accept( &mut self, cx: &mut Context<'_>, ) -> Poll<Result<(Self::Io, Self::Addr)>>

Polls to accept a new incoming connection to this listener.

fn local_addr(&self) -> Result<Self::Addr>

Returns the local address that this listener is bound to.

Provided Methods

fn accept(&mut self) -> ListenerAcceptFut<'_, Self>

where Self: Sized,

Accepts a new incoming connection from this listener.
