devel/hs-indexed-traversable - The NetBSD Packages Collection

FunctorWithIndex, FoldableWithIndex, TraversableWithIndex

This package provides three useful generalizations:

class Functor f => FunctorWithIndex i f | f -> i where
  imap :: (i -> a -> b) -> f a -> f b

class Foldable f => FoldableWithIndex i f | f -> i where
  ifoldMap :: Monoid m => (i -> a -> m) -> f a -> m

class (FunctorWithIndex i t, FoldableWithIndex i t, Traversable t)
      => TraversableWithIndex i t | t -> i where
  itraverse :: Applicative f => (i -> a -> f b) -> t a -> f (t b)

This package contains instances for types in GHC boot libraries. For
some additional instances see indexed-traversable-instances.

The keys package provides similar functionality, but uses (associated)
TypeFamilies instead of FunctionalDependencies.
