Effect.Aff.Bus

make :: forall m a. MonadEffect m => m (BusRW a)

Creates a new bidirectional Bus which can be read from and written to.

read :: forall a r. BusR' r a -> Aff a

Blocks until a new value is pushed to the Bus, returning the value.

write :: forall a r. a -> BusW' r a -> Aff Unit

Pushes a new value to the Bus, yieldig immediately.

split :: forall a. BusRW a -> Tuple (BusR a) (BusW a)

Splits a bidirectional Bus into separate read and write Buses.

kill :: forall a r. Error -> BusW' r a -> Aff Unit

Kills the Bus and propagates the exception to all pending and future consumers.

isKilled :: forall m a r. MonadEffect m => BusR' r a -> m Boolean

Synchronously checks whether a Bus has been killed.
