A trait for representing equivalence relations.
This would conflict with all the nice implicit Orderings available, but thanks to the magic of prioritized implicits via subclassing we can make Ordered[A] => Ordering[A] only turn up if nothing else works.
A trait for totally ordered data.
A trait for representing total orderings.
A trait for representing partial orderings.
A class for partially ordered data.
