This is the mock extension of `rusty_phoenix_socket` the Rust version of https://gitlab.in2p3.fr/CTA-LAPP/PHOENIX_LIBS2/network/PhoenixSocket project. This project aims to ease the use of socket in complex environments, especially distributed environments where latencies measurement has to be precise and reproductible when running unit tests. **rustyphoenixsocketmock** provides : - A mock backend, **PMockBackend**, which can play, register and replay a sequence of socket calls (send/recv)
