This module provides PerformEventT, the standard implementation of PerformEvent.

Documentation

newtype PerformEventT t m a

FireCommand

Fields

• runFireCommand :: forall a. [DSum (EventTrigger t) Identity] -> ReadPhase m a -> m [a]

hostPerformEventT :: forall t m a. (Monad m, MonadSubscribeEvent t m, MonadReflexHost t m, MonadRef m, Ref m ~ Ref IO) => PerformEventT t m a -> m (a, FireCommand t m)

Run a PerformEventT action, returning a FireCommand that allows the caller to trigger Events while ensuring that performEvent actions are run at the appropriate time.
