1. header :: [ByteString] -> Header

   cassava	Data.Csv

   Construct a header from a list of ByteStrings.

2. headerOrder :: DefaultOrdered a => a -> Header

   cassava	Data.Csv

   The header order for this record. Should include the names used in the NamedRecord returned by toNamedRecord. Pass undefined as the argument, together with a type annotation e.g. headerOrder (undefined :: MyRecord).

3. header :: Word8 -> Parser Header

   cassava	Data.Csv.Parser

   Parse a header, including the terminating line separator.

4. headTail :: forall (n :: Nat) . (KnownNat n, 1 <= n) => R n -> (ℝ, R (n - 1))

   hmatrix	Numeric.LinearAlgebra.Static

   No documentation available.

5. headEx :: MonoFoldable mono => mono -> Element mono

   mono-traversable	Data.MonoTraversable

   Get the first element of a monomorphic container. Note: this is a partial function. On an empty MonoFoldable, it will throw an exception. See head from Data.NonNull for a total version of this function.

6. headMay :: MonoFoldable mono => mono -> Maybe (Element mono)

   mono-traversable	Data.MonoTraversable

   Safe version of headEx. Returns Nothing instead of throwing an exception when encountering an empty monomorphic container.

7. headMaybe :: [a] -> Maybe a

   rio	RIO.List

   No documentation available.

8. headM :: Monad m => Vector a -> m a

   rio	RIO.Vector.Boxed.Partial

   No documentation available.

9. headM :: (Vector v a, Monad m) => v a -> m a

   rio	RIO.Vector.Partial

   No documentation available.

10. headM :: (Storable a, Monad m) => Vector a -> m a

    rio	RIO.Vector.Storable.Partial

    No documentation available.
