Module UuidSource

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

Sourcetype t

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

include Core_kernel.Identifiable.S with type t := t
include Bin_prot.Binable.S with type t := t
include Bin_prot.Binable.S_only_functions with type t := t
Sourceval bin_size_t : t Bin_prot.Size.sizer
Sourceval bin_write_t : t Bin_prot.Write.writer
Sourceval bin_read_t : t Bin_prot.Read.reader
Sourceval __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.

Sourceval bin_shape_t : Bin_prot.Shape.t

Sourceval (<=) : t -> t -> bool

Sourceval (>) : t -> t -> bool
Sourceval (<) : t -> t -> bool
Sourceval (<>) : t -> t -> bool
Sourceval equal : t -> t -> bool
Sourceval 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.

Sourceval min : t -> t -> t
Sourceval max : t -> t -> t
Sourceval 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.

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

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

Sourceval 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).

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