Module Base.Maybe_bound

Used for specifying a bound (either upper or lower) as inclusive, exclusive, or unbounded.

type 'a t =
| Incl of 'a
| Excl of 'a
| Unbounded
val all : 'a list -> 'a t list
include Sexpable.S1 with type 'a t := 'a t
val t_of_sexp : (Sexp.t -> 'a) -> Sexp.t -> 'a t
val sexp_of_t : ('a -> Sexp.t) -> 'a t -> Sexp.t
val map : 'a t -> f:('a -> 'b) -> 'b t
val is_lower_bound : 'a t -> of_:'a -> compare:('a -> 'a -> int) -> bool
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.

| In_range
| Above_upper_bound

val interval_comparison_of_sexp : Sexp.t -> interval_comparison

val hash_interval_comparison : interval_comparison -> Hash.hash_value
val compare_to_interval_exn : lower:'a t -> upper:'a t -> 'a -> compare:('a -> 'a -> int) -> interval_comparison

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