Althoug the specification says this can be a type alias for another generator (that is default constructible), in this implementation it is using an operating system methods to create UUIDs (`CoCreateGuid` on Windows, `uuid_generate` on Linux, `CFUUIDCreate` on Mac) |

| ` basic_uuid_random_generator` | a function object that generates version 4 UUIDs using a pseudo-random number generator engine. |

| `uuid_name_generator` | a function object that generates version 5, name-based UUIDs using SHA1 hashing. |
