BrokerCapabilities class
Runtime-declared capabilities of a broker adapter.
This is intentionally additive to the Broker contract. Existing adapters can continue implementing the legacy getters while callers use a single snapshot when deciding whether to expose optional operations.
Constructors
- BrokerCapabilities({required bool supportsDelayedDelivery, required bool supportsPriorityOrdering, BrokerDeliveryGuarantee deliveryGuarantee = BrokerDeliveryGuarantee.unknown, bool supportsBroadcastFanout = false, bool supportsQueueInspection = false, bool supportsLeaseExtension = false, bool supportsDeadLettering = false, bool supportsDeadLetterReplay = false})
-
Creates a broker capability snapshot.
