#Distributive
class Distributive :: (Type -> Type) -> Constraint
class (Functor f) <= Distributive f where
Categorical dual of Traversable
:
distribute
is the dual ofsequence
- it zips an arbitrary collection of containers.collect
is the dual oftraverse
- it traverses an arbitrary collection of values.
Laws:
distribute = collect identity
distribute <<< distribute = identity
collect f = distribute <<< map f
map f = unwrap <<< collect (Identity <<< f)
map distribute <<< collect f = unwrap <<< collect (Compose <<< f)
Members
distribute :: forall a g. Functor g => g (f a) -> f (g a)

Instances
Distributive Identity
Distributive (Function e)
(TypeEquals a Unit) => Distributive (Tuple a)
#distributeDefault
distributeDefault :: forall a f g. Distributive f => Functor g => g (f a) -> f (g a)
