A trait for extending TcpListener types.

Required Methods§

source

fn new(address_family: AddressFamily, blocking: Blocking) -> Result<Self>

Creates a new TCP socket with the given address family.

The created socket is not bound or connected to any address and may be used for either listening or connecting. Use PoolExt::bind_existing_tcp_listener to bind it in preparation for listening, or PoolExt::connect_into_tcp_stream to initiate a connection.

This is similar to Pool::bind_tcp_listener in that it creates a TCP socket, however it does not perform the bind or listen steps. And, it has a blocking argument to select blocking or non-blocking mode for the created socket.

And it’s similar to Pool::connect_tcp_stream in that it creates a TCP socket, however it does not perform the connect step. And, it has a blocking argument to select blocking or non-blocking mode for the created socket.

source

fn listen(&self, backlog: Option<i32>) -> Result<()>

Enble listening in a TcpListener.

A newly-created TcpListener created with TcpListenerExt::new and bound with PoolExt::bind_existing_tcp_listener is not yet listening; this function enables listening. After this, the listener may accept new connections with accept or accept_with.

This is similar to Pool::bind_tcp_listener in that it performs the listen step, however it does not create the socket itself, or bind it.

The backlog argument specifies an optional hint to the implementation about how many connections can be waiting before new connections are refused or ignored.
