RFC 4122 defines different UUID versions. The version shows
how a UUID was generated, e.g. a version 4 UUID was generated
from a random number, a version 3 UUID from an MD5 hash of a name.
Note:
All of these UUID versions can be read and processed by
std.uuid, but only version 3, 4 and 5 UUIDs can be generated.
