Caseless compares and hashes strings ignoring case, so that for example Caseless.equal "OCaml" "ocaml" and Caseless.("apple" < "Banana") are true.

Caseless also provides case-insensitive is_suffix and is_prefix functions, so that for example Caseless.is_suffix "OCaml" ~suffix:"AmL" and Caseless.is_prefix "OCaml" ~prefix:"oc" are true.

val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).
