function RpcBaseHeader🔗

explicit RpcBaseHeader(
    const cxx::UniqueId & uniqueClientQueueId,
    const uint32_t lastKnownClientQueueIndex,
    const int64_t sequenceId,
    const uint8_t rpcHeaderVersion
)

Constructs and initializes a RpcBaseHeader.

Parameters:

  • uniqueClientQueueId is the cxx::UniqueId of the client queue where the response shall be delivered
  • lastKnownClientQueueIndex is the last know index of the client queue in the ChunkDistributor for fast lookup
  • sequenceId is a custom ID to map a response to a request
  • rpcHeaderVersion is set by RequestHeader/ResponseHeader and should be RPC_HEADER_VERSION

  • data width of members changes
  • members are rearranged
  • semantic meaning of a member changes in any of RpcBaseHeader, RequestHeader or ResponseHeader!

variable UNKNOWN_CLIENT_QUEUE_INDEX🔗

static constexpr uint32_t UNKNOWN_CLIENT_QUEUE_INDEX {std::numeric_limits<uint32_t>::max()};

variable START_SEQUENCE_ID🔗

static constexpr int64_t START_SEQUENCE_ID {0};
