1. mapSpecItem_ :: (Item a -> Item b) -> SpecWith a -> SpecWith b

   hspec-core	Test.Hspec.Core.Spec

   No documentation available.

2. mapFoldable :: forall (m :: Type -> Type) t a b r . (Functor m, Foldable t) => (a -> t b) -> Pipe a b m r

   pipes	Pipes.Prelude

   Apply a function to all values flowing downstream, and forward each element of the result.

3. mapM :: Monad m => (a -> m b) -> Pipe a b m r

   pipes	Pipes.Prelude

   Apply a monadic function to all values flowing downstream

   mapM return = cat
   
   mapM (f >=> g) = mapM f >-> mapM g
   

4. mapM_ :: Monad m => (a -> m ()) -> Consumer' a m r

   pipes	Pipes.Prelude

   Consume all values using a monadic function

5. mapMaybe :: forall (m :: Type -> Type) a b r . Functor m => (a -> Maybe b) -> Pipe a b m r

   pipes	Pipes.Prelude

   (mapMaybe f) yields Just results of f. Basic laws:

   mapMaybe (f >=> g) = mapMaybe f >-> mapMaybe g
   
   mapMaybe (pure @Maybe . f) = mapMaybe (Just . f) = map f
   
   mapMaybe (const Nothing) = drain
   

   As a result of the second law,

   mapMaybe return = mapMaybe Just = cat
   

6. mapComposeT :: forall f (g :: (Type -> Type) -> Type -> Type) (m :: Type -> Type) a p (q :: (Type -> Type) -> Type -> Type) (n :: Type -> Type) b . (f (g m) a -> p (q n) b) -> ComposeT f g m a -> ComposeT p q n b

   mmorph	Control.Monad.Trans.Compose

   Transform the computation inside a ComposeT.

7. mapAccum :: (a -> b -> (a, c)) -> a -> CharMap b -> (a, CharMap c)

   regex-tdfa	Data.IntMap.CharMap2

   No documentation available.

8. mapAccumWithKey :: (a -> Key -> b -> (a, c)) -> a -> CharMap b -> (a, CharMap c)

   regex-tdfa	Data.IntMap.CharMap2

   No documentation available.

9. mapEither :: (a -> Either b c) -> CharMap a -> (CharMap b, CharMap c)

   regex-tdfa	Data.IntMap.CharMap2

   No documentation available.

10. mapEitherWithKey :: (Key -> a -> Either b c) -> CharMap a -> (CharMap b, CharMap c)

    regex-tdfa	Data.IntMap.CharMap2

    No documentation available.
