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
