UUID Value

Typed representation of a UUID. Under the hood, UUIDs are treated as quasi-strings, much like URLs are. This class holds the implementation details for a wrapped or generated UUID, and behaves as a string from a guest perspective. Parsing and encoding happen at construction time; UUIDValue objects never exist in an invalid state.

Generating a UUID uses an optimized internal structure, which is only serialized to a string on-demand. If a UUID is generated and never converted to a string, no string encoding occurs.

If a string happens to be available (for instance, when a UUID is constructed from a string), it is cached after parsing occurs.
