  1. mapToDMap :: Map k v -> DMap (Const2 k v) Identity

    patch Data.Functor.Misc

    Convert a regular Map to a DMap

  2. mapIntMapPatchWithKey :: (Int -> a -> b) -> PatchIntMap a -> PatchIntMap b

    patch Data.Patch

    Map a function Int -> a -> b over all as in the given PatchIntMap a (that is, all inserts/updates), producing a PatchIntMap b.

  3. mapIntMapPatchWithKey :: (Int -> a -> b) -> PatchIntMap a -> PatchIntMap b

    patch Data.Patch.IntMap

    Map a function Int -> a -> b over all as in the given PatchIntMap a (that is, all inserts/updates), producing a PatchIntMap b.

  4. mapAccumL :: (acc -> x -> (acc, y)) -> acc -> [x] -> (acc, [y])

    prelude-compat Data.List2010

    No documentation available.

  5. mapAccumR :: (acc -> x -> (acc, y)) -> acc -> [x] -> (acc, [y])

    prelude-compat Data.List2010

    No documentation available.

  6. mapM :: (Traversable t, Monad m) => (a -> m b) -> t a -> m (t b)

    prelude-compat Prelude2010

    Map each element of a structure to a monadic action, evaluate these actions from left to right, and collect the results. For a version that ignores the results see mapM_.

    Examples

    mapM is literally a traverse with a type signature restricted to Monad. Its implementation may be more efficient due to additional power of Monad.

  7. mapM_ :: (Foldable t, Monad m) => (a -> m b) -> t a -> m ()

    prelude-compat Prelude2010

    Map each element of a structure to a monadic action, evaluate these actions from left to right, and ignore the results. For a version that doesn't ignore the results see mapM. mapM_ is just like traverse_, but specialised to monadic actions.

  8. mapLeft :: Bifunctor p => (a -> b) -> p a c -> p b c

    rebase Rebase.Data.Bifunctor

    A more meaningful and conflict-free alias for first.

  9. mapRight :: Bifunctor p => (b -> c) -> p a b -> p a c

    rebase Rebase.Data.Bifunctor

    A more meaningful and conflict-free alias for second.

  10. mapM :: Monad m => (a -> m b) -> Vector a -> m (Vector b)

    rebase Rebase.Data.Vector

    No documentation available.
