1. mapMaybe :: forall s k a b . (a -> Maybe b) -> Map s k a -> SomeMapWith (SupersetProof 'Regular s) k b

   refined-containers	Data.Map.Strict.Refined

   Apply a function to all values in a map and collect only the Just results, returning a potentially smaller map.

2. mapMaybeWithKey :: (Key s k -> a -> Maybe b) -> Map s k a -> SomeMapWith (SupersetProof 'Regular s) k b

   refined-containers	Data.Map.Strict.Refined

   Apply a function to all values in a map, together with their corresponding keys, and collect only the Just results, returning a potentially smaller map.

3. mapWithKey :: (Key s k -> a -> b) -> Map s k a -> Map s k b

   refined-containers	Data.Map.Strict.Refined

   Apply a function to all values in a map, together with their corresponding keys, that are proven to be in the map. The set of keys remains the same.

4. mapOp :: (Functor f, HasField s "mapOp" a) => LensLike' f s a

   riak-protobuf	Data.Riak.Proto

   No documentation available.

5. mapValue :: (Functor f, HasField s "mapValue" a) => LensLike' f s a

   riak-protobuf	Data.Riak.Proto

   No documentation available.

6. mapSelected :: forall (f :: Type -> Type) a c b . Functor f => (a -> c) -> Selection f b a -> Selection f b c

   selections	Data.Functor.Selection

   Map over selected values

   mapSelected = fmap
   

7. mapUnselected :: forall (f :: Type -> Type) b c a . Functor f => (b -> c) -> Selection f b a -> Selection f c a

   selections	Data.Functor.Selection

   Map over unselected values

   mapUnselected = first
   

8. mapException :: (Exception e1, Exception e2, MonadCatch m) => (e1 -> e2) -> m a -> m a

   servant-exceptions-server	Servant.Exception.Server

   Catch and rethrow using mapping function f.

9. 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.

10. 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.
