Type Alias SimpleAxon 

pub type SimpleAxon<In, Out, Res = ()> = Axon<In, Out, String, Res>;

Axon with String error — the most common pattern for examples and prototyping.

Aliased Type

}

Fields

schematic: Schematic

The static structure (for visualization/analysis)

execution_mode: ExecutionMode

How this Axon is executed across the cluster

persistence_store: Option<Arc<dyn PersistenceStore>>

Optional persistence store for state inspection

audit_sink: Option<Arc<dyn AuditSink>>

Optional audit sink for tamper-evident logging of interventions

dlq_sink: Option<Arc<dyn DlqSink>>

Optional dead-letter queue sink for storing failed events

dlq_policy: DlqPolicy

Policy for handling event failures

dynamic_dlq_policy: Option<DynamicPolicy<DlqPolicy>>

Optional dynamic (hot-reloadable) DLQ policy — takes precedence over static dlq_policy

saga_policy: SagaPolicy

Policy for automated saga compensation

dynamic_saga_policy: Option<DynamicPolicy<SagaPolicy>>

Optional dynamic (hot-reloadable) Saga policy — takes precedence over static saga_policy

saga_compensation_registry: Arc<RwLock<SagaCompensationRegistry<String, Res>>>

Registry for Saga compensation handlers

iam_handle: Option<IamHandle>

Optional IAM handle for identity verification at the Schematic boundary
