    buf: &mut [u8]

Reads data from a substream. The behaviour is the same as futures::AsyncRead::poll_read.

pub fn write_substream(

    cx: &mut Context<'_>,
    sub: &mut <EitherOutput<A, B> as StreamMuxer>::Substream
) -> Poll<Result<(), <EitherOutput<A, B> as StreamMuxer>::Error>>

Attempts to shut down the writing side of a substream. The behaviour is similar to AsyncWrite::poll_close.

pub fn destroy_substream(
    &self,
    substream: <EitherOutput<A, B> as StreamMuxer>::Substream
)

Destroys a substream.

pub fn close(

Flush this StreamMuxer.

fn is_remote_acknowledged(&self) -> bool

👎 Deprecated:

This method is unused and will be removed in the future

Returns true if the remote has shown any sign of activity after the muxer has been open.
