  1. mapM :: Monad m => (a -> m b) -> ConduitT a b m ()

    conduit Data.Conduit.Combinators

    Apply a monadic transformation to all values in a stream. If you do not need the transformed values, and instead just want the monadic side-effects of running the action, see mapM_. Subject to fusion

  2. mapME :: (Monad m, Traversable f) => (a -> m b) -> ConduitT (f a) (f b) m ()

    conduit Data.Conduit.Combinators

    Apply a monadic transformation to all elements in a chunked stream. Subject to fusion

  3. mapM_ :: Monad m => (a -> m ()) -> ConduitT a o m ()

    conduit Data.Conduit.Combinators

    Apply the action to all values in the stream. Note: if you want to pass the values instead of consuming them, use iterM instead. Subject to fusion

  4. mapM_E :: (Monad m, MonoFoldable mono) => (Element mono -> m ()) -> ConduitT mono o m ()

    conduit Data.Conduit.Combinators

    Apply the action to all elements in the chunked stream. Note: the same caveat as with mapM_ applies. If you don't want to consume the values, you can use iterM:

    iterM (omapM_ f)
    
    Subject to fusion

  5. mapWhile :: forall (m :: Type -> Type) a b . Monad m => (a -> Maybe b) -> ConduitT a b m ()

    conduit Data.Conduit.Combinators

    Map values as long as the result is Just.

  6. mapAccumWhileMS :: Monad m => (a -> s -> m (Either s (s, b))) -> s -> StreamConduitT a b m s

    conduit Data.Conduit.Combinators.Stream

    No documentation available.

  7. mapAccumWhileS :: forall (m :: Type -> Type) a s b . Monad m => (a -> s -> Either s (s, b)) -> s -> StreamConduitT a b m s

    conduit Data.Conduit.Combinators.Stream

    No documentation available.

  8. mapInput :: forall (m :: Type -> Type) i1 i2 l2 l1 o u r . Monad m => (i1 -> i2) -> (l2 -> Maybe l1) -> Pipe l2 i2 o u m r -> Pipe l1 i1 o u m r

    conduit Data.Conduit.Internal

    Apply a function to all the input values of a Pipe. Since 0.5.0

  9. mapOutput :: forall (m :: Type -> Type) o1 o2 l i u r . Monad m => (o1 -> o2) -> Pipe l i o1 u m r -> Pipe l i o2 u m r

    conduit Data.Conduit.Internal

    Apply a function to all the output values of a Pipe. This mimics the behavior of fmap for a Source and Conduit in pre-0.4 days. Since 0.4.1

  10. mapOutputMaybe :: forall (m :: Type -> Type) o1 o2 l i u r . Monad m => (o1 -> Maybe o2) -> Pipe l i o1 u m r -> Pipe l i o2 u m r

    conduit Data.Conduit.Internal

    Same as mapOutput, but use a function that returns Maybe values. Since 0.5.0
