Detailed Description

Abstract hook a caller implements to drive recovery against a replay or retransmission service when a sequence gap is detected.

The library never performs network I/O itself: when SequenceTracker sees a gap it calls request_retransmit, and the caller is responsible for issuing the actual re-request (for example a SoupBinTCP/MoldUDP64 rewind request) and feeding the recovered messages back through the decoder.

request_retransmit()

virtual auto itch::transport::RetransmitRequester::request_retransmit ( std::string_view  session, std::uint64_t  start_sequence, std::uint64_t  count  ) -> void

pure virtual
