fastuuidv7 0.1.4

Python bindings for fast-uuid-v7.

fastuuidv7

Python bindings for the Rust fast-uuid-v7 generator.

This package is intentionally small. It exposes the fast Rust UUIDv7 generator to Python with a module name of fastuuidv7 and keeps the API close to the Rust crate.

Install locally

cd python
maturin develop

Usage

import fastuuidv7

raw = fastuuidv7.gen_id()
text = fastuuidv7.gen_id_str()
data = fastuuidv7.gen_id_bytes()

same_text = fastuuidv7.format_uuid(raw)

Convenience aliases:

fastuuidv7.uuid7()
fastuuidv7.uuid7_bytes()

Benchmarks

cd python
python3 bench/bench.py

The benchmark measures repeated single calls, so the numbers include Python/native boundary overhead.

Current results on linux git runner:

Package	Callable	Time per call
uuid6	uuid6.uuid7	2890.4 ns/call
uuid7	uuid_extensions.uuid7	2767.7 ns
fastuuid7	uuidv7.uuid7	313.5 ns
fastuuidv7	fastuuidv7.uuid7	60.6 ns

Notes:

• These are single-call throughput measurements, so they include Python/native boundary overhead.

Notes

• Python 3.14 includes uuid.uuid7() in the standard library.
• The main use case here is speed experiments and using a fast Rust-backed generator on older Python versions.
