A uuid contains the raw bytes for a UUID.
Note that this is intentially a struct with no constructors, no destructor, and no user-defined assignment operators so that it remains a POD.
See also:
The UUID data is stored as an array of 16 8-bit bytes comprising the 128 bits that is a UUID. The data is intentionally not stored as shown in "Appendix A - Sample Implementation" of RFC 4122 (the struct with individial fields such as time_low, time_mid, etc.) since C++ does not guarantee that the struct fields will be laid out in memory as shown in section "4.1.2. Layout and Byte Order" due to possible padding.
