Module Core_kernel.Maybe_bound

This module extends Base.Maybe_bound with bin_io and with compare functions in the form of As_lower_bound and As_upper_bound modules.

val is_upper_bound : 'a t -> of_:'a -> compare:('a -> 'a -> int) -> bool
val interval_contains_exn : lower:'a t -> upper:'a t -> 'a -> compare:('a -> 'a -> int) -> bool

interval_contains_exn ~lower ~upper x ~compare raises if lower and upper are crossed.

val bounds_crossed : lower:'a t -> upper:'a t -> compare:('a -> 'a -> int) -> bool

bounds_crossed ~lower ~upper ~compare returns true if lower > upper.

It ignores whether the bounds are Incl or Excl.

compare_to_interval_exn ~lower ~upper x ~compare raises if lower and upper are crossed.

module As_lower_bound : sig ... end

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:

module As_upper_bound : sig ... end

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:

module Stable : sig ... end
