Module `Maybe_bound.As_lower_bound`

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

Unbounded < ... < Incl 13 < Excl 13 < Incl 14 < Excl 14 < ...

type nonrec 'a t = 'a t

val compare : ('a -> 'a -> int) -> 'a t -> 'a t -> int
