4. fmapMaybeUB :: (a -> b) -> MaybeUB a -> MaybeUB b

   ghc	GHC.Data.Unboxed

   No documentation available.

5. intMapMaybe :: Int -> T (IntMap elem) (Maybe elem)

   data-accessor	Data.Accessor.Container

   No documentation available.

6. contramapMaybe :: (a -> Maybe b) -> OutputStream b -> IO (OutputStream a)

   io-streams	System.IO.Streams.Combinators

   Contravariant counterpart to contramapMaybe. contramap f s passes all input to s through the function f. Discards all the elements for which f returns Nothing. Since: 1.2.1.0

7. contramapMaybeGLogFunc :: (a -> Maybe b) -> GLogFunc b -> GLogFunc a

   rio	RIO

   A vesion of contramapMaybeGLogFunc which supports filering.

8. imapMaybe :: (Vector v a, Vector v b) => (Int -> a -> Maybe b) -> v a -> v b

   rio	RIO.Vector

   No documentation available.

9. imapMaybe :: (Int -> a -> Maybe b) -> Vector a -> Vector b

   rio	RIO.Vector.Boxed

   No documentation available.

10. imapMaybe :: (Storable a, Storable b) => (Int -> a -> Maybe b) -> Vector a -> Vector b

    rio	RIO.Vector.Storable

    No documentation available.
