Required methods

fn poll_send_to(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &[u8],
    receiver: &Self::Receiver
) -> Poll<Result<usize, Self::Err>>

Sends data on the IO interface to the specified target.

On success, returns the number of bytes written.

fn poll_recv_from(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut [u8]
) -> Poll<Result<(usize, Self::Sender), Self::Err>>

Receives data from the IO interface.

On success, returns the number of bytes read and the target from whence the data came.
