runTriggerEventT :: TriggerEventT t m a -> Chan [DSum (EventTriggerRef t) TriggerInvocation] -> m a Source #

Run a TriggerEventT action. The argument should be a Chan into which TriggerInvocations can be passed; it is expected that some other thread will be responsible for popping values out of the Chan and firing their EventTriggers.

askEvents :: Monad m => TriggerEventT t m (Chan [DSum (EventTriggerRef t) TriggerInvocation]) Source #

Retrieve the current Chan; event trigger invocations pushed into it will be fired.

data TriggerInvocation a Source #

A value with which to fire an Event, as well as a callback to invoke after its propagation has completed.

Constructors

TriggerInvocation a (IO ())

newtype EventTriggerRef t a Source #

A reference to an EventTrigger suitable for firing with TriggerEventT.

Constructors

EventTriggerRef
Fields unEventTriggerRef :: IORef (Maybe (EventTrigger t a))
