tvarEventStoreReader :: TVar (EventMap event) -> VersionedEventStoreReader STM event Source #
An EventStoreReader that stores events in a TVar and runs in STM.
This functions initializes the store by creating the TVar and hooking up
the event store API to that TVar.
tvarEventStoreWriter :: TVar (EventMap event) -> EventStoreWriter STM event Source #
tvarGlobalEventStoreReader :: TVar (EventMap event) -> GlobalEventStoreReader STM event Source #
Analog of tvarEventStoreReader for a GlobalEventStoreReader
stateEventStoreReader :: MonadState (EventMap event) m => VersionedEventStoreReader m event Source #
Specialized version of embeddedStateEventStoreReader that only contains an
EventMap in the state.
stateEventStoreWriter :: MonadState (EventMap event) m => EventStoreWriter m event Source #
Specialized version of embeddedStateEventStoreWriter that only contains an
EventMap in the state.
stateGlobalEventStoreReader :: MonadState (EventMap event) m => GlobalEventStoreReader m event Source #
embeddedStateEventStoreReader :: MonadState s m => (s -> EventMap event) -> VersionedEventStoreReader m event Source #
An EventStore that runs on some MonadState that contains an
EventMap. This is useful if you want to include other state in your
MonadState.
embeddedStateEventStoreWriter :: MonadState s m => (s -> EventMap event) -> (s -> EventMap event -> s) -> EventStoreWriter m event Source #
embeddedStateGlobalEventStoreReader :: MonadState s m => (s -> EventMap event) -> GlobalEventStoreReader m event Source #
Analogous to embeddedStateEventStore for a GlobalStreamEventStore.
Internal data structure used for the in-memory event stores.
emptyEventMap :: EventMap event Source #
What it says on the tin, an initialized empty EventMap
