/*
Universally Unique Identifiers (`UUID`) according to [[ RFC 4122 ; https://tools.ietf.org/html/rfc4122.html ]], with additions from [[ RFC 9562 ; https://tools.ietf.org/html/rfc9562.html ]].

The UUIDs are textually represented and read in the following string format:
`00000000-0000-v000-V000-000000000000`

`v` is where the version bits reside, and `V` is where the variant bits reside.
The meaning of the other bits is version-dependent.

Outside of string representations, UUIDs are represented in memory by a 128-bit
structure organized as an array of 16 bytes.


Of the UUID versions which may make use of random number generation, a
requirement is placed upon them that the underlying generator be
cryptographically-secure, per RFC 9562's suggestion.

- Version 1 without a node argument.
- Version 4 in all cases.
- Version 6 without either a clock or node argument.
- Version 7 in all cases.

Example:	
	package main

	import "core:crypto"
	import "core:encoding/uuid"

	main :: proc() {
		my_uuid: uuid.Identifier

		{
			// This scope will have a CSPRNG.
			context.random_generator = crypto.random_generator()
			my_uuid = uuid.generate_v7()
		}

		// Back to the default random number generator.
	}
