newtype FireCommand t m Source #

A function that fires events for the given EventTriggers and then runs any followup actions provided via PerformEvent. The given ReadPhase action will be run once for the initial trigger execution as well as once for each followup.

Fields

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) Source #

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.
