Module type Predicate.OrderedType

Input signature of the functor Make.

type t

The type of the elements in the set.

The chosen t must be infinite.

val compare : t -> t -> int

A total ordering function over the set elements. This is a two-argument function f such that:

  • f e1 e2 is zero if the elements e1 and e2 are equal,
  • f e1 e2 is strictly negative if e1 is smaller than e2,
  • and f e1 e2 is strictly positive if e1 is greater than e2.
