data Ordering :: Type

The Ordering kind represents the three possibilities of comparing two types of the same kind: LT (less than), EQ (equal to), and GT (greater than).

data LT :: Ordering

The 'less than' ordering type.

data GT :: Ordering

The 'greater than' ordering type.

data EQ :: Ordering

The 'equal to' ordering type.
