1. foldMapM :: (Monad m, Monoid b) => (a -> m b) -> Fold m a b

   streamly-core	Streamly.Internal.Data.Fold

   Definition:

   >>> foldMapM f = Fold.lmapM f Fold.mconcat
   

   Make a fold from a monadic function that folds the output of the function using mappend and mempty.

   >>> sum = Fold.foldMapM (return . Data.Monoid.Sum)
   
   >>> Stream.fold sum $ Stream.enumerateFromTo 1 10
   Sum {getSum = 55}
   

2. lmapM :: Monad m => (a -> m b) -> Fold m b r -> Fold m a r

   streamly-core	Streamly.Internal.Data.Fold

   lmapM f fold maps the monadic function f on the input of the fold.

3. rmapM :: Monad m => (b -> m c) -> Fold m a b -> Fold m a c

   streamly-core	Streamly.Internal.Data.Fold

   Map a monadic function on the output of a fold.

4. rollingMapM :: Monad m => (Maybe a -> a -> m b) -> Fold m a b

   streamly-core	Streamly.Internal.Data.Fold

   Apply a function on every two successive elements of a stream. The first argument of the map function is the previous element and the second argument is the current element. When processing the very first element in the stream, the previous element is Nothing. Pre-release

5. windowRollingMapM :: Monad m => (Maybe a -> a -> m (Maybe b)) -> Fold m (a, Maybe a) (Maybe b)

   streamly-core	Streamly.Internal.Data.Fold

   Apply an effectful function on the latest and the oldest element of the window.

6. rmapM :: Monad m => (b -> m c) -> ChunkFold m a b -> ChunkFold m a c

   streamly-core	Streamly.Internal.Data.Fold.Chunked

   Map a monadic function on the output of a fold. Pre-release

7. lmapM :: Monad m => (a -> m b) -> Parser b m r -> Parser a m r

   streamly-core	Streamly.Internal.Data.Parser

   lmapM f parser maps the monadic function f on the input of the parser.

8. rmapM :: Monad m => (b -> m c) -> Parser a m b -> Parser a m c

   streamly-core	Streamly.Internal.Data.Parser

   rmapM f parser maps the monadic function f on the output of the parser.

   >>> rmap = fmap
   

9. lmapM :: Monad m => (a -> m b) -> Refold m c b r -> Refold m c a r

   streamly-core	Streamly.Internal.Data.Refold.Type

   lmapM f fold maps the monadic function f on the input of the fold. Internal

10. rmapM :: Monad m => (b -> m c) -> Refold m x a b -> Refold m x a c

    streamly-core	Streamly.Internal.Data.Refold.Type

    Map a monadic function on the output of a fold. Internal
