Description

Improving values -- efficient version

Synopsis

data Improving a = Imp { exact :: a compareI :: a -> Ordering } exactly :: Ord a => a -> Improving a minI :: Ord a => Improving a -> Improving a -> (Improving a, Bool) maxI :: Ord a => Improving a -> Improving a -> (Improving a, Bool)

Documentation

data Improving a Source

An improving value. Constructors Imp exact :: a compareI :: a -> Ordering Instances Eq a => Eq (Improving a) Ord a => Ord (Improving a) EqProp a => EqProp (Improving a)

exactly :: Ord a => a -> Improving a Source

A known improving value (which doesn't really improve)

minI :: Ord a => Improving a -> Improving a -> (Improving a, Bool) Source

Efficient combination of min and '(<=)'

maxI :: Ord a => Improving a -> Improving a -> (Improving a, Bool) Source

Efficient combination of max and '(>=)'
