1. mapMaybe :: (a -> Maybe b) -> [a] -> [b]

   strict-base-types	Data.Maybe.Strict

   Analogous to mapMaybe in Data.Maybe.

2. mapAffix :: (String -> String) -> (String -> String) -> Formatted a -> Formatted a

   table-layout	Text.Layout.Table.Cell.Formatted

   Map over the formatting directives of a formatted value.

3. mapRowGroupColumns :: [(b, a -> b)] -> RowGroup a -> [[b]]

   table-layout	Text.Layout.Table.Spec.RowGroup

   Map each column with the corresponding function and replace empty inputs with the given value.

4. mapEitherT :: (m (Either x a) -> n (Either y b)) -> EitherT x m a -> EitherT y n b

   transformers-either	Control.Monad.Trans.Either

   No documentation available.

5. mapTuple :: Int -> ExpQ

   tuple-th	TupleTH

   Type of the generated expression:

   (a -> b) -> (a, ..) -> (b, ..)
   

6. mapTuple' :: Int -> ExpQ -> Q Exp

   tuple-th	TupleTH

   Takes the mapping as a quoted expression. This can sometimes produce an expression that typechecks when the analogous expression using filterTuple does not, e.g.:

   $(mapTuple 2) Just        ((),"foo") -- Type error
   $(mapTuple' 2 [| Just |]) ((),"foo") -- OK
   

7. mapM :: MonadUnliftIO m => (a -> m b) -> InputStream a -> m (InputStream b)

   unliftio-streams	UnliftIO.Streams.Combinators

   No documentation available.

8. mapBufferM :: (a -> IO b) -> Buffer a -> IO (Vector b)

   vector-buffer	Data.Vector.Buffer

   monadic map over a buffer

9. mapBufferM_ :: (a -> IO b) -> Buffer a -> IO ()

   vector-buffer	Data.Vector.Buffer

   monadic map over a buffer

10. mapBufferM :: (Prim a, Prim b) => (a -> IO b) -> Buffer a -> IO (Vector b)

    vector-buffer	Data.Vector.Primitive.Buffer

    monadic map over a buffer
