Description

For compatibility across different versions of the barbie package.

Synopsis

class FunctorB (b :: (k -> Type) -> Type) where
- bmap :: (forall (a :: k). f a -> g a) -> b f -> b g
class FunctorB b => TraversableB (b :: (k -> Type) -> Type) where
- btraverse :: Applicative e => (forall (a :: k). f a -> e (g a)) -> b f -> e (b g)
newtype Rec p a (x :: k) = Rec {
- unRec :: K1 R a x
}

Documentation

class FunctorB (b :: (k -> Type) -> Type) where #

Barbie-types that can be mapped over. Instances of FunctorB should satisfy the following laws:

bmap id = id
bmap f . bmap g = bmap (f . g)

There is a default bmap implementation for Generic types, so instances can derived automatically.

class FunctorB b => TraversableB (b :: (k -> Type) -> Type) where #

Barbie-types that can be traversed from left to right. Instances should satisfy the following laws:

 t . btraverse f   = btraverse (t . f)  -- naturality
btraverse Identity = Identity           -- identity
btraverse (Compose . fmap g . f) = Compose . fmap (btraverse g) . btraverse f -- composition

There is a default btraverse implementation for Generic types, so instances can derived automatically.
