1. mapU :: (u -> u') -> DUALTree d u a l -> DUALTree d u' a l

   dual-tree	Data.Tree.DUAL.Internal

   Map a function over all the u annotations in a DUAL-tree. The function must be a monoid homomorphism, and must commute with the action of d on u. That is, to use mapU f safely it must be the case that

   • f mempty == mempty

   • f (u1 <> u2) == f u1 <> f u2

   • f (act d u) == act d (f u)

2. mapUNE :: (u -> u') -> DUALTreeNE d u a l -> DUALTreeNE d u' a l

   dual-tree	Data.Tree.DUAL.Internal

   Map a function (which must be a monoid homomorphism, and commute with the action of d) over all the u annotations in a non-empty DUAL-tree.

3. mapUU :: (u -> u') -> DUALTreeU d u a l -> DUALTreeU d u' a l

   dual-tree	Data.Tree.DUAL.Internal

   Map a function (which must be a monoid homomorphism, and commute with the action of d) over all the u annotations in a non-empty DUAL-tree paired with its cached u value.

4. mapConcurrently :: forall f (es :: [Effect]) a b . (HasCallStack, Traversable f, Concurrent :> es) => (a -> Eff es b) -> f a -> Eff es (f b)

   effectful	Effectful.Concurrent.Async

   Lifted mapConcurrently.

5. mapConcurrently_ :: forall f (es :: [Effect]) a b . (HasCallStack, Foldable f, Concurrent :> es) => (a -> Eff es b) -> f a -> Eff es ()

   effectful	Effectful.Concurrent.Async

   Lifted mapConcurrently_.

6. mapM :: (Vector v a, Vector v b, Applicative f) => (a -> f b) -> v a -> f (v b)

   fixed-vector	Data.Vector.Fixed

   Effectful map over vector.

7. mapM_ :: (Vector v a, Applicative f) => (a -> f b) -> v a -> f ()

   fixed-vector	Data.Vector.Fixed

   Apply monadic action to each element of vector and ignore result.

8. mapM :: forall (n :: PeanoNum) f a b . (ArityPeano n, Applicative f) => (a -> f b) -> ContVec n a -> f (ContVec n b)

   fixed-vector	Data.Vector.Fixed.Cont

   Effectful map over vector.

9. mapM_ :: forall (n :: PeanoNum) f a b . (ArityPeano n, Applicative f) => (a -> f b) -> ContVec n a -> f ()

   fixed-vector	Data.Vector.Fixed.Cont

   Apply monadic action to each element of vector and ignore result.

10. mapG :: (Vector v a, Vector w b, Dim v ~ Dim w) => (a -> b) -> v a -> w b

    fixed-vector	Data.Vector.Fixed.Generic

    Map over vector
