Switching Pip to Uv in a Dockerized Flask / Django App

I am totally against Python tooling being written in a language other than Python. I get that C extensions exist and for the most part Python is synonymous with CPython.

I think 2 languages are enough, we don't need a 3rd one that nobody asked for.

I have nothing against Rust. If you want a new tool, go for it. If you want a re-write of an existing tool, go for it. I'm against it creeping into an existing eco-system for no reason.

A popular Python package called Pendulum went over 7 months without support for 3.13. I have to imagine this is because nobody in the Python community knew enough Rust to fix it. Had the native portion of Pendulum been written in C I would have fixed it myself.

In my ideal world if someone wanted fast datetimes written in Rust (or any other language other than C) they'd write a proper library suitable for any language to consume over FFI.

So far this Rust stuff has left a bad taste in my mouth and I don't blame the Linux community for being resistant.

According to the very link you provide, the sticking point was a dependency which does not use rust, and the maintainer probably being busy.

I updated a rust-implemented wheel to 3.13 compat myself and literally all that required was bumping pyo3 (which added support back in June) and adding the classifier. Afaik cryptography had no trouble either, iirc what they had to wait on was a 3.13 compatible cffi .

The PR which enabled 3.13 did have changes to Rust code.
