This aligns the public API of the `libp2p-mplex` module with the one
from `libp2p-yamux`. This change has two benefits:
1. For standalone users of `libp2p-mplex`, the substreams itself are
now useful, similar to `libp2p-yamux` and don't necessarily need to
be polled via the `StreamMuxer`. The `StreamMuxer` only forwards to
the `Async{Read,Write}` implementations.
2. This will reduce the diff of #2648 because we can chunk the one
giant commit into smaller atomic ones.

I've benchmarked this branch separately and cannot reliably find any regressions. The benchmarks do sometimes report changes in the 5% range but those are not stable so I think this change is harmless for performance. |

Agreed. I like that this is making it more consistent with Thanks isolating this change! |

Is this a breaking change?

Yes because Substream is a public type and has type parameter now!

v0.46.0 is not yet released, thus no need to bump to v0.47.0.

Description
This aligns the public API of the
libp2p-mplexmodule with the onefrom
libp2p-yamux. This change has two benefits:For standalone users of
libp2p-mplex, the substreams itself arenow useful, similar to
libp2p-yamuxand don't necessarily need tobe polled via the
StreamMuxer. TheStreamMuxeronly forwards tothe
Async{Read,Write}implementations.This will reduce the diff of core/muxing: Redesign
StreamMuxertrait #2648 because we can chunk the onegiant commit into smaller atomic ones.
Whilst keeping master functional, the state of
StreamMuxeris nowa bit awkward until we merge #2648. However, given we are already
doing things this way for
libp2p-yamuxit shouldn't be an issue?Links to any relevant issues
Will reduce diff in #2648.
