Structs

EventStoreAggregateContext

PersistedSnapshotStore

Storage engine using a database backing. This is an snapshot-sourced EventStore, meaning it uses the serialized aggregate as the primary source of truth for the state of the aggregate.

QueryContext

A data structure maintaining context when updating views.
