- * UUID - Universally Unique IDentifier - 128 bits unique number.
- * There are 5 versions and one variant of UUID defined by RFC4122
- * specification. A UUID contains a set of fields. The set varies
- * depending on the version of the UUID, as shown below:
- * - time, MAC address(v1),
- * - user ID(v2),
- * - MD5 of name or URL(v3),
- * - random data(v4),
- * - SHA-1 of name or URL(v5),
- *
- * Layout of UUID:
- * timestamp - 60-bit: time_low, time_mid, time_hi_and_version
- * version - 4 bit (bit 4 through 7 of the time_hi_and_version)
- * clock seq - 14 bit: clock_seq_hi_and_reserved, clock_seq_low
- * variant: - bit 6 and 7 of clock_seq_hi_and_reserved
- * node - 48 bit
- *
- * source: https://www.ietf.org/rfc/rfc4122.txt
- *
- * UUID binary format (16 bytes):
- *
- * 4B-2B-2B-2B-6B (big endian - network byte order)
- *
- * UUID string is 36 length of characters (36 bytes):
- *
- * 0 9 14 19 24
- * xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
- * be be be be be
- *
- * where x is a hexadecimal character. Fields are separated by '-'s.
- * When converting to a binary UUID, le means the field should be converted
- * to little endian and be means it should be converted to big endian.
- *
- * UUID is also used as GUID (Globally Unique Identifier) with the same binary
- * format but it differs in string format like below.
- *
- * GUID:
- * 0 9 14 19 24
- * xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
- * le le le be be
- *
- * GUID is used e.g. in GPT (GUID Partition Table) as a partiions unique id.
