Public Attributes Documentation

variable sender_id

uint32_t sender_id = 0;

Stable producer tiebreaker for topology-keyed multi-producer queues. Connection::conn_id is deterministic for a fixed topology, so same-cycle fan-in does not depend on runtime thread placement.

variable receiver_generation_snapshot

uint64_t receiver_generation_snapshot = 0;

variable epoch_snapshot

uint64_t epoch_snapshot = 0;

variable enqueue_cycle

uint64_t enqueue_cycle = 0;

Producer's localCycle at push time (arrive_cycle - delay). Used by StageSelective predicates to decide whether a message was in-flight at the time of a flush.

variable data

T data;

variable cancel_epoch

const std::atomic< uint64_t > * cancel_epoch = nullptr;

nullptr => not cancelable
