1. mapMaybe :: (a -> Maybe b) -> InputStream a -> IO (InputStream b)

   io-streams	System.IO.Streams.Combinators

   A version of map that discards elements mapMaybe f s passes all output from s through the function f and discards elements for which f s evaluates to Nothing. Example:

   ghci> Streams.fromList [Just 1, None, Just 3] >>=
   Streams.mapMaybe id >>=
   Streams.toList
   [1,3]
   

   Since: 1.2.1.0

2. mapFromList :: IsMap map => [(ContainerKey map, MapValue map)] -> map

   mono-traversable	Data.Containers

   Convert a list of key-value pairs to a map

3. mapKeysWith :: (BiPolyMap map, BPMKeyConstraint map k1, BPMKeyConstraint map k2) => (v -> v -> v) -> (k1 -> k2) -> map k1 v -> map k2 v

   mono-traversable	Data.Containers

   No documentation available.

4. mapToList :: IsMap map => map -> [(ContainerKey map, MapValue map)]

   mono-traversable	Data.Containers

   Convert a map to a list of key-value pairs.

5. mapWithKey :: IsMap map => (ContainerKey map -> MapValue map -> MapValue map) -> map -> map

   mono-traversable	Data.Containers

   Apply a function over every key-value pair of a map.

6. mapM_ :: (MonoFoldable mono, Applicative m) => (Element mono -> m ()) -> mono -> m ()

   mono-traversable	Data.MonoTraversable.Unprefixed

   Synonym for omapM_

7. mapNonNull :: (Functor f, MonoFoldable (f b)) => (a -> b) -> NonNull (f a) -> NonNull (f b)

   mono-traversable	Data.NonNull

   fmap over the underlying container in a NonNull.

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

   strict	Data.Strict.Maybe

   Analogous to mapMaybe in Data.Maybe.

9. mapToDecoder :: (b -> a) -> Codec context any b -> Codec context Void a

   autodocodec	Autodocodec

   Map a codec for decoding bs into a decoder for as. This is useful for building discriminatedUnionCodecs.

10. mapToEncoder :: b -> Codec context b any -> Codec context a ()

    autodocodec	Autodocodec

    Wrap up a value of type b with its codec to produce and encoder for as that ignores its input and instead encodes the value b. This is useful for building discriminatedUnionCodecs.
