Exact lookup

1. headDefC :: forall (m :: Type -> Type) a o . Monad m => a -> ConduitT a o m a

   conduit	Conduit

   Same as headC, but returns a default value if none are available from the stream.

2. headDef :: forall (m :: Type -> Type) a o . Monad m => a -> ConduitT a o m a

   conduit	Data.Conduit.Combinators

   Same as head, but returns a default value if none are available from the stream.

3. headE :: forall (m :: Type -> Type) seq o . (Monad m, IsSequence seq) => ConduitT seq o m (Maybe (Element seq))

   conduit	Data.Conduit.Combinators

   Get the next element in the chunked stream.

4. headS :: forall (m :: Type -> Type) a . Monad m => StreamConsumer a m (Maybe a)

   conduit	Data.Conduit.Internal.List.Stream

   No documentation available.

5. headline :: Doc SimpleHtml -> Doc SimpleHtml

   prettyprinter	Prettyprinter.Render.Tutorials.StackMachineTutorial

   No documentation available.

6. headline :: Doc SimpleHtml -> Doc SimpleHtml

   prettyprinter	Prettyprinter.Render.Tutorials.TreeRenderingTutorial

   No documentation available.

7. headDef :: a -> [a] -> a

   safe	Safe

   No documentation available.

8. headErr :: Partial => [a] -> a

   safe	Safe

   Identical to head, namely that fails on an empty list. Useful to avoid the x-partial warning introduced in GHC 9.8.

   headErr [] = error "Prelude.head: empty list"
   headErr [1,2,3] = 1
   

9. headMay :: [a] -> Maybe a

   safe	Safe

   No documentation available.

10. headNote :: Partial => String -> [a] -> a

    safe	Safe

    No documentation available.
