ErrorId A bounded, stack-allocated diagnostic label of at most N UTF-8 bytes. Events A non-empty collection of domain events with compile-time capacity. EventsIntoIter Owning iterator over Events Version A monotonically increasing event version number. VersionedEvent An event paired with its version in the aggregate’s event sequence. KernelError DEFAULT_ERROR_ID_CAP Default capacity for an ErrorId DEFAULT_MAX_REHYDRATION_EVENTS Default maximum events during rehydration via replay.
Override per-aggregate via Aggregate::MAX_REHYDRATION_EVENTS. Aggregate Type-level specification binding state, error, and ID types. AggregateState State of an event-sourced aggregate. Mutated by applying domain events. DomainEvent Handle Per-command handler trait — the decide function. Id Marker for a type usable as a stream / aggregate id. Message React Per-incoming-event-type handler — the react function, dual of
Handle<C, N> Saga Saga-level contract. A saga is an aggregate whose events are its own
history, plus how to route incoming events and how each own-event maps to an
outgoing intent. EventOf Shorthand for accessing the event type of an aggregate. aggregate Attribute macro that transforms a unit struct into an aggregate newtype. DomainEvent
