cpp-uuid 1.0.0

Python UUID module written in C++

cpp_uuid is a Python library written in C++. It provides an API that, in most cases, covers usage of Python’s builtin UUID class. The library implements generate, convert to string and parse UUIDs version 4. It is also possible to convert UUIDs from uuid standard or compare between them.

In most cases you can just replace import section of your code.

from cpp_uuid import UUID, uuid4

item_uuid = uuid4()
other_uuid = UUID('c5fcf05c-6320-47ec-98c0-be84fdb1c321')

Module tested on Python versions from 3.8 to 3.12.

This library uses UUID4 generation from crashoz/uuid_v4 library.

Benchmarks

Performance comparisons were made with the standard uuid and the fastuuid library, which is written in Rust.
