Control.Carrier.Cull.Church

Description

A carrier for Cull and NonDet effects used in tandem (Cull :+: NonDet).

Since: 1.0.0.0

Synopsis

Cull carrier

runCull :: (m b -> m b -> m b) -> (a -> m b) -> m b -> CullC m a -> m b Source #

Run a Cull effect with continuations respectively interpreting <|>, pure, and empty. Branches outside of any cull block will not be pruned.

Since: 1.0.0.0

runCullA :: (Alternative f, Applicative m) => CullC m a -> m (f a) Source #

Run a Cull effect, interpreting the result into an Alternative functor. Choice is handled with <|>, embedding with pure, and failure with empty.

Since: 1.0.0.0

runCullM :: (Applicative m, Monoid b) => (a -> b) -> CullC m a -> m b Source #

Run a Cull effect, mapping results into a Monoid.

Since: 1.0.0.0
