version

expect val Uuid.version: Int

The version of the Uuid, denoting the generating algorithm.

0 – special case for the Nil UUID
1 – time-based
2 – DCE security
3 – name-based using MD5 hashing
4 – random or pseudo-random
5 – name-based using SHA-1 hashing
6–15 – reserved for future extension

Note that the version returned by this function is only meaningful if the Uuid.variant is RFC 4122.
