  1. mapInputM :: Monad m => (i1 -> m i2) -> (i2 -> m (Maybe i1)) -> ConduitT i2 o m r -> ConduitT i1 o m r

    classy-prelude-conduit ClassyPrelude.Conduit

    Apply a monadic action to all the input values of a ConduitT. Since 1.3.2

  2. mapMC :: Monad m => (a -> m b) -> ConduitT a b m ()

    classy-prelude-conduit ClassyPrelude.Conduit

    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_.

  3. mapMCE :: (Monad m, Traversable f) => (a -> m b) -> ConduitT (f a) (f b) m ()

    classy-prelude-conduit ClassyPrelude.Conduit

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

  4. mapM_C :: Monad m => (a -> m ()) -> ConduitT a o m ()

    classy-prelude-conduit ClassyPrelude.Conduit

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

  5. mapM_CE :: (Monad m, MonoFoldable mono) => (Element mono -> m ()) -> ConduitT mono o m ()

    classy-prelude-conduit ClassyPrelude.Conduit

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

    iterM (omapM_ f)

  6. mapOutput :: forall (m :: Type -> Type) o1 o2 i r . Monad m => (o1 -> o2) -> ConduitT i o1 m r -> ConduitT i o2 m r

    classy-prelude-conduit ClassyPrelude.Conduit

    Apply a function to all the output values of a ConduitT. This mimics the behavior of fmap for a Source and Conduit in pre-0.4 days. It can also be simulated by fusing with the map conduit from Data.Conduit.List. Since 0.4.1

  7. mapOutputMaybe :: forall (m :: Type -> Type) o1 o2 i r . Monad m => (o1 -> Maybe o2) -> ConduitT i o1 m r -> ConduitT i o2 m r

    classy-prelude-conduit ClassyPrelude.Conduit

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

  8. mapWhileC :: forall (m :: Type -> Type) a b . Monad m => (a -> Maybe b) -> ConduitT a b m ()

    classy-prelude-conduit ClassyPrelude.Conduit

    Map values as long as the result is Just.

  9. mapHeadedness :: (forall x . () => h x -> h' x) -> Colonnade h a c -> Colonnade h' a c

    colonnade Colonnade

    Map over the header type of a Colonnade.

  10. mapHeaderContent :: forall (h :: Type -> Type) c a . Functor h => (c -> c) -> Colonnade h a c -> Colonnade h a c

    colonnade Colonnade

    Map over the content in the header. This is similar performing fmap on a Colonnade except that the body content is unaffected.
