effect :: Monad m => (a -> m b) -> Conduit a m a Source #
Performs the effect but ignores its result. The original value is propagated downstream.
effect' :: Monad m => m b -> Conduit a m a Source #
Performs the effect but ignores its result. The original value is propagated downstream.
tapWith :: Monad m => Conduit a m b -> Sink b m () -> Conduit a m a Source #
Taps the stream by applying a transformation and sending the transformed value into a given sink. The original value is then propagated downstream.
tapWith projectLefts myErrorSink
tap :: Monad m => Sink a m () -> Conduit a m a Source #
Taps into a given sink. The original value is then propagated downstream.
tapPred :: Monad m => (a -> Bool) -> Sink a m () -> Sink a m () -> Conduit a m a Source #
Taps a conduit, and sends the results into two different sinks, switching on a predicate.
sinkWithPred :: Monad m => (a -> Bool) -> Sink a m () -> Sink a m () -> Sink a m () Source #
Creates a unified sink, which is actually two separate sinks with results being sent to one or the other based on a predicate.
projectNothings :: Monad m => Conduit (Maybe a) m () Source #
Projects nothings from the stream. Returns a stream that only contains nothings (represented by unit)
projectLefts :: Monad m => Conduit (Either l r) m l Source #
Projects left side values for each value in a stream. Downstream only receives values that were on the left side, the right side is ignored.
projectRights :: Monad m => Conduit (Either l r) m r Source #
Projects right side values for each value in a stream. Downstream only receives values that were on the right side, the left side is ignored.
divertLeft :: Monad m => Sink l m () -> Conduit (Either l r) m r Source #
Sends every left-side value in a stream into a given Sink
.
Downstream receives only right-side values.
