Methods
ifoldMap1 :: Semigroup m => (i -> a -> m) -> f a -> m Source #
Map each element of the structure to a semigroup, and combine the results.
ifoldMap1' :: Semigroup m => (i -> a -> m) -> f a -> m Source #
A variant of ifoldMap1 that is strict in the accumulator.
ifoldrMap1 :: (i -> a -> b) -> (i -> a -> b -> b) -> f a -> b Source #
Generalized ifoldr1.
ifoldlMap1' :: (i -> a -> b) -> (i -> b -> a -> b) -> f a -> b Source #
Generalized ifoldl1'.
ifoldlMap1 :: (i -> a -> b) -> (i -> b -> a -> b) -> f a -> b Source #
Generalized ifoldl1.
ifoldrMap1' :: (i -> a -> b) -> (i -> a -> b -> b) -> f a -> b Source #
Generalized ifoldr1'.
