null package:conduit

null :: Monad m => ConduitT a o m Bool
conduit Data.Conduit.Combinators
True if there are no values in the stream. This function does not modify the stream.
nullC :: Monad m => ConduitT a o m Bool
conduit Conduit
True if there are no values in the stream. This function does not modify the stream.
nullCE :: (Monad m, MonoFoldable mono) => ConduitT mono o m Bool
conduit Conduit
True if there are no elements in the chunked stream. This function may remove empty leading chunks from the stream, but otherwise will not modify it.
nullE :: (Monad m, MonoFoldable mono) => ConduitT mono o m Bool
conduit Data.Conduit.Combinators
True if there are no elements in the chunked stream. This function may remove empty leading chunks from the stream, but otherwise will not modify it.
awaitNonNull :: (Monad m, MonoFoldable a) => ConduitT a o m (Maybe (NonNull a))
conduit Conduit Data.Conduit.Combinators
Same as await, but discards any leading onull values.
sinkNull :: Monad m => ConduitT a o m ()
conduit Conduit Data.Conduit.Combinators
Consume and discard all remaining values in the stream. Subject to fusion
sinkNullS :: Monad m => StreamConsumer a m ()
conduit Data.Conduit.Internal.List.Stream
sourceNullS :: Monad m => StreamProducer m a
conduit Data.Conduit.Internal.List.Stream
sinkNull :: Monad m => ConduitT i o m ()
conduit Data.Conduit.List
Ignore the remainder of values in the source. Particularly useful when combined with isolate. Subject to fusion Since 0.3.0
sourceNull :: Monad m => ConduitT i o m ()
conduit Data.Conduit.List
A source that outputs no values. Note that this is just a type-restricted synonym for mempty. Subject to fusion Since 0.3.0
