Add request-response protocol

[flcl42]

Protocol

Generic request-response protocol, to be used as base for user define protocols with custom id, request and response types serialized with protobuf

Details

• Type: app layer protocol

• Spec: user:

  • implements custom handling logic that receives REQUEST type and returns object of RESPONSE type;
  • defines protocol id,
  • registers protocol

  listener:

  • accepts a connection,
  • receives data,
  • de-serializes it into REQUEST type,
  • allows handling logic to process the request,
  • sends serialized response to dialer and
  • closes the connection

  dialer:

  • allows to send custom request and receive response using particular DialAsync method override

TODO

• [ ] Implement generic protocol, that implements ISessionProtocol<TRequest, TResponse> protocol;
• [ ] Add a generic extension method that receives logic handling method, protocol id; and registers protocol as AddAppLayerProtocol does
• [ ] Add docs
• [ ] Add tests

@flcl42 : Hi Aleksey. As discussed @namay26 will be working on interop engineering between dotnet-libp2p and py-libp2p. He has made key contributions to py-libp2p in the past.

As a starting project assignment in dotnet-libp2p, I am asking him to contribute to it while working with us.

@namay26 : Please reach out to us on dotnet-libp2p discord if you encounter any issues.
