core_kernel v0.17.0 · OCaml Package

Thread-safe generation of random identifiers in the UUID format.

This library is not RFC 4122 compliant: the version is set in the output, but the variant is not.

type t

When am_running_test, sexp_of_t masks the UUID, showing only "<uuid-omitted-in-test>". You can use Unstable.sexp_of_t if you definitely want to see it within your tests.

val bin_write_t : t Bin_prot.Write.writer

val bin_read_t : t Bin_prot.Read.reader

val __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.

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 ~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).
