  1. mapMaybeM :: Monad m => (a -> m (Maybe b)) -> Stream m a -> Stream m b

    streamly-core Streamly.Internal.Data.Stream

    Like mapMaybe but maps a monadic function. Equivalent to:

    >>> mapMaybeM f = Stream.catMaybes . Stream.mapM f
    
    >>> mapM f = Stream.mapMaybeM (\x -> Just <$> f x)
    

  2. mapMSerial :: Monad m => (a -> m b) -> StreamK m a -> StreamK m b

    streamly-core Streamly.Internal.Data.StreamK

    No documentation available.

  3. mapMWith :: (m b -> StreamK m b -> StreamK m b) -> (a -> m b) -> StreamK m a -> StreamK m b

    streamly-core Streamly.Internal.Data.StreamK

    No documentation available.

  4. mapM_ :: Monad m => (a -> m b) -> StreamK m a -> m ()

    streamly-core Streamly.Internal.Data.StreamK

    Apply a monadic action to each element of the stream and discard the output of the action.

  5. mapMaybe :: forall a b (m :: Type -> Type) . (a -> Maybe b) -> StreamK m a -> StreamK m b

    streamly-core Streamly.Internal.Data.StreamK

    No documentation available.

  6. mapM2 :: Monad m => (a -> b -> m c) -> Unfold m a b -> Unfold m a c

    streamly-core Streamly.Internal.Data.Unfold

    No documentation available.

  7. mapMaybe :: (Arrow arrow, Functor f) => (a -> Maybe b) -> arrow (f [a]) (f [b])

    synthesizer-midi Synthesizer.MIDI.CausalIO.Process

    No documentation available.

  8. mapM_ :: Monad m => (a -> m b) -> Stream m a -> m ()

    vector-stream Data.Stream.Monadic

    Execute a monadic action for each element of the Stream

  9. mapMaybe :: forall (m :: Type -> Type) a b . Monad m => (a -> Maybe b) -> Stream m a -> Stream m b

    vector-stream Data.Stream.Monadic

    No documentation available.

  10. mapMaybeM :: Monad m => (a -> m (Maybe b)) -> Stream m a -> Stream m b

    vector-stream Data.Stream.Monadic

    Apply monadic function to each element and drop all Nothings
