Struct AggregateBuilder 

Source 
pub struct AggregateBuilder<'a, R, A> { /* private fields */ }
Expand description

Builder for loading aggregates by ID.

Implementations§

Source§

impl<S, C, A> AggregateBuilder<'_, Repository<S, C, NoSnapshots<S::Id, S::Position>>, A>
where S: EventStore, C: ConcurrencyStrategy, A: Aggregate<Id = S::Id>,

Source

pub async fn load( self, id: &S::Id, ) -> Result<A, ProjectionError<S::Error, <S::Codec as Codec>::Error>>
where A::Event: ProjectionEvent,

Load the aggregate instance by replaying events (no snapshots).

The event kinds to load are automatically determined from the aggregate’s event type via ProjectionEvent::EVENT_KINDS.

§Errors

Returns an error if the store fails to load events or if events cannot be deserialized.

Source§

impl<S, SS, C, A> AggregateBuilder<'_, Repository<S, C, Snapshots<SS>>, A>
where S: EventStore, SS: SnapshotStore<Id = S::Id, Position = S::Position>, C: ConcurrencyStrategy, A: Aggregate<Id = S::Id> + Serialize + DeserializeOwned,

Source

pub async fn load( self, id: &S::Id, ) -> Result<A, ProjectionError<S::Error, <S::Codec as Codec>::Error>>
where A::Event: ProjectionEvent,

Load the aggregate instance using snapshots when available.

The event kinds to load are automatically determined from the aggregate’s event type via ProjectionEvent::EVENT_KINDS.

§Errors

Returns an error if events cannot be deserialized or a stored snapshot cannot be deserialized (which indicates snapshot data corruption).
