class HFunctor h where

Higher-order functors of kind (* -> *) -> (* -> *) map functors to functors.

All effects must be HFunctors.

Minimal complete definition

Nothing

Methods

fmap' :: Functor (h f) => (a -> b) -> h f a -> h f b

Deprecated: fmap' has been subsumed by fmap.

Apply a handler specified as a natural transformation to both higher-order and continuation positions within an HFunctor.

hmap :: Functor m => (forall x. m x -> n x) -> h m a -> h n a

Higher-order functor map of a natural transformation over higher-order positions within the effect.

A definition for hmap over first-order effects can be derived automatically provided a Generic1 instance is available.

hmap :: (Functor m, Generic1 (h m), Generic1 (h n), GHFunctor m n (Rep1 (h m)) (Rep1 (h n))) => (forall x. m x -> n x) -> h m a -> h n a

Higher-order functor map of a natural transformation over higher-order positions within the effect.
