type ProjectionMap key orderKey serialized = Map key (orderKey, serialized) Source #
A ProjectionMap just stores the latest snapshot for each UUID.
emptyProjectionMap :: ProjectionMap key orderKey serialized Source #
projectionMapTVar :: IO (TVar (ProjectionMap key orderKey serialized)) Source #
tvarProjectionCache :: Ord key => TVar (ProjectionMap key orderKey serialized) -> ProjectionCache key orderKey serialized STM Source #
A ProjectionCache that uses a TVar and runs in STM.
embeddedStateProjectionCache :: (MonadState s m, Ord key) => (s -> ProjectionMap key orderKey serialized) -> (s -> ProjectionMap key orderKey serialized -> s) -> ProjectionCache key orderKey serialized m Source #
A ProjectionCache for some MonadState that contains a ProjectionMap.
