A post-mortem on building natsort-rs, fixing a 45x performance bug, and catching subtle edge cases with a custom Pytest monkeypatch bridge.


Why natsort?
Porting Python code to Rust using the "Astral playbook" sounds straightforward on paper: rewrite the hot path, compile to native binary, profit. We chose Seth M. Morton’s popular natsort...
