Data.Semigroup.Bifoldable

Description

Re-exports a subset of the Data.Bifoldable1 module along with some additional combinators that require `Bifoldable1` constraints.

Synopsis

- class Bifoldable t => Bifoldable1 (t :: Type -> Type -> Type) where
  - bifold1 :: Semigroup m => t m m -> m
  - bifoldMap1 :: Semigroup m => (a -> m) -> (b -> m) -> t a b -> m
- bitraverse1_ :: (Bifoldable1 t, Apply f) => (a -> f b) -> (c -> f d) -> t a c -> f ()
- bifor1_ :: (Bifoldable1 t, Apply f) => t a c -> (a -> f b) -> (c -> f d) -> f ()
- bisequenceA1_ :: (Bifoldable1 t, Apply f) => t (f a) (f b) -> f ()
- bifoldMapDefault1 :: (Bifoldable1 t, Monoid m) => (a -> m) -> (b -> m) -> t a b -> m
