Caseless (base.Base.String.Caseless)

Caseless compares and hashes strings ignoring case, so that for example Caseless.equal "OCaml" "ocaml" and Caseless.("apple" < "Banana") are true, and Caseless.Map, Caseless.Table lookup and Caseless.Set membership is case-insensitive. 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.

type t

val (>=) : t ‑> t ‑> bool

val (<=) : t ‑> t ‑> bool

val (=) : t ‑> t ‑> bool

val (>) : t ‑> t ‑> bool

val (<) : t ‑> t ‑> bool

val (<>) : t ‑> t ‑> bool

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 ~cmp: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

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).
