libghc-indexed-traversable-dev - 0.1.3-1 main

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 provides a library for the Haskell programming language.
