Module Core_kernel__Maybe_bound.As_upper_bound

Compares t values as upper bounds, where Unbounded is highest, Incl x > Excl x, and other cases of Incl and/or Excl are compared based on 'a. If As_upper_bound.compare compare_a t1 t2 <= 0 and is_upper_bound t1 ~of_:a ~compare, then is_upper_bound t2 ~of_:a ~compare. For example, for int As_upper_bound.t:

... < Excl 13 < Incl 13 < Excl 14 < Incl 14 < ... < Unbounded
type nonrec 'a t = 'a t
val compare : ('a -> 'a -> int) -> 'a t -> 'a t -> int
