Instances
bitraverse1_ :: ( Bifoldable1 t, Apply f) => (a -> f b) -> (c -> f d) -> t a c -> f () Source #
bifor1_ :: ( Bifoldable1 t, Apply f) => t a c -> (a -> f b) -> (c -> f d) -> f () Source #
bisequenceA1_ :: ( Bifoldable1 t, Apply f) => t (f a) (f b) -> f () Source #
bifoldMapDefault1 :: ( Bifoldable1 t, Monoid m) => (a -> m) -> (b -> m) -> t a b -> m Source #
Usable default for foldMap, but only if you define bifoldMap1 yourself
