Module admission_queue

Structs§

AdmissionQueueContext: Shared handle to a live admission queue. Holds the manager (for spawning a fresh per-epoch actor on reconfig), the per-epoch ArcSwap handle, and the cached (config-derived) bypass threshold. Cloned cheaply by Arc; passed both to ValidatorService (for hot-path routing) and through ValidatorComponents (for epoch rotation).
AdmissionQueueHandle: Cloneable handle for submitting transactions to the admission queue actor. Held by RPC handlers; the actor runs in a separate spawned task.
AdmissionQueueManager: Manages the lifecycle of per-epoch admission queue actors. Holds immutable config and shared metrics; call spawn() each epoch with the new epoch store to create a fresh actor and handle.
AdmissionQueueMetrics: Prometheus metrics for the admission queue.
InsertOutcome: Outcome of PriorityAdmissionQueue::try_insert. Any displaced entry is carried here unnotified so that the caller can deliver the notification outside of any held locks.
PriorityAdmissionQueue: Bounded priority queue that orders transactions by gas price. Uses a BTreeMap for efficient access at both ends: lowest gas price (for eviction) and highest gas price (for draining to consensus). Entries at the same gas price are FIFO.
QueueEntry: A transaction (or soft bundle) waiting in the admission queue for consensus submission.

PopAction: What PriorityAdmissionQueue::pop_batch_while does with an examined entry.
