runCutA :: (Alternative f, Applicative m) => CutC m a -> m (f a)
runCutM :: (Applicative m, Monoid b) => (a -> b) -> CutC m a -> m b
newtype CutC m a = CutC (forall b. (a -> m b -> m b) -> m b -> m b -> m b)

module Control.Effect.NonDet

Cut carrier

runCut :: (a -> m b -> m b) -> m b -> m b -> CutC m a -> m b Source #

Run a Cut effect with continuations respectively interpreting pure / <|>, empty, and cutfail.

runCut cons nil fail (pure a <|> empty) = cons a nil

runCut cons nil fail cutfail = fail

runCut cons nil fail (call cutfail) = nil

Since: 1.0.0.0

runCutA :: (Alternative f, Applicative m) => CutC m a -> m (f a) Source #

Run a Cut effect, returning all its results in an Alternative collection.

Since: 1.0.0.0

runCutM :: (Applicative m, Monoid b) => (a -> b) -> CutC m a -> m b Source #

Run a Cut effect, mapping results into a Monoid.

Since: 1.0.0.0
