class (Monad m, MemberEffect Lift (Lift m) l) => EffectLift m l Source #
An effect described by a monad.
runLift :: Monad m => Effect (Lift m :+ Nil) a -> m a Source #
Converts a computation containing only monadic effects into a monadic computation.
lift :: EffectLift m l => m a -> Effect l a Source #
Lifts a monadic value into an effect.
liftEffect :: EffectLift m l => m (Effect l a) -> Effect l a Source #
Lifts a monadic value into an effect.
