Class type

Implements universally unique identifiers based on version 3 of the UUID specification. Identifier generation is thread safe, and fast.

type t

When am_running_test, sexp_of_t shows all zeros (the nil UUID).

  • deprecated [since 2017-11] Use a [Stable] or [Unstable] [t_of_sexp].
val create : unit -> t
  • deprecated [since 2018-10] Use [Uuid.create_random] or [Uuid_unix.create]
val create_random : Core_kernel.Random.State.t -> t
val to_string_hum : t -> string

to_string_hum t is like to_string, except when am_running_test, in which case it shows all zeros (the nil UUID).
