Trait Listener 

pub trait Listener: Send + 'static {
    type Io: AsyncRead + AsyncWrite + Unpin + Send + 'static;
    type Addr: Send;

    // Required methods
    fn accept(&mut self) -> impl Future<Output = (Self::Io, Self::Addr)> + Send;
    fn local_addr(&self) -> Result<Self::Addr, Error>;
}

Types that can listen for connections.

Required Associated Types

type Io: AsyncRead + AsyncWrite + Unpin + Send + 'static

The listener’s IO type.

type Addr: Send

The listener’s address type.

Required Methods

fn accept(&mut self) -> impl Future<Output = (Self::Io, Self::Addr)> + Send

Accept a new incoming connection to this listener.

If the underlying accept call can return an error, this function must take care of logging and retrying.

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

Returns the local address that this listener is bound to.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl Listener for TcpListener

type Io = TcpStream

type Addr = SocketAddr

async fn accept( &mut self, ) -> (<TcpListener as Listener>::Io, <TcpListener as Listener>::Addr)

fn local_addr(&self) -> Result<<TcpListener as Listener>::Addr, Error>

impl Listener for UnixListener

Available on Unix only.

type Io = UnixStream

type Addr = SocketAddr

async fn accept( &mut self, ) -> (<UnixListener as Listener>::Io, <UnixListener as Listener>::Addr)

fn local_addr(&self) -> Result<<UnixListener as Listener>::Addr, Error>

Implementors

impl<L, F> Listener for TapIo<L, F>

where L: Listener, F: FnMut(&mut <L as Listener>::Io) + Send + 'static,

type Io = <L as Listener>::Io

type Addr = <L as Listener>::Addr
