FastUUID is a library which provides CPython bindings to Rust's UUID library.
The provided API is exactly as Python's builtin UUID class.
It is supported on Python 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, & 3.13.
It is much faster than Python's pure-python implementation and it is stricter when parsing hexadecimal representation of UUIDs.
If you need to generate a lot of random UUIDs we also provide the uuid4_bulk()
function which releases the GIL for the entire duration of the generation.
This allows other threads to run while the library generates UUIDs.
