Enum InboxDispatchOutcome

Namespace

Trellis.Mediator

Assembly

Trellis.Mediator.dll

The outcome of dispatching one message through DispatchAsync(IntegrationEnvelope, CancellationToken): whether this call committed the handlers' side effects, or the message was already processed so this call committed nothing. Both outcomes mean the message is durably accounted for, so a pull consumer can safely advance its checkpoint on either; the distinction exists for metrics, logging, and overlap / anti-join bookkeeping.

public enum InboxDispatchOutcome

Fields

Processed = 0

The message was new: its handlers ran and their side effects committed atomically with the dedup record in this call.

SkippedDuplicate = 1

The (ConsumerId, MessageId) pair was already processed, so this call committed nothing. Usually a redelivery caught on the fast path before any handler runs; if instead a concurrent dispatch won the race, the handlers ran but their writes rolled back with the duplicate-key save. Either way no local side effects were applied by this call.
