Port for other languages like C++, C# or JavaScript

[ZhaoXiangXML]

I think it's theoretically possible to port PyO3 to support other object-oriented languages like C++ (with smart pointers), C# or JavaScript.

PyO3 has done a great job on exporting Rust to Python with memory management, subclassing and other great stuff. I think these features can be shared with other OO languages so people can write modules in Rust and use them in like C++.

I understand it's a large project. I'd like to know if I want to start on this path where should I start.

Maybe https://github.com/dtolnay/cxx is what you're looking for, at least for C++?

Agree with this. PyO3 is very specialised for Python bindings and I don't think you'll find much joy from trying to generalise it to other languages. Better to use cxx or other projects tailored for that specific language.

It's just really annoying to implement bindings for different languages while they have so much in common.

Have you considered https://github.com/Dushistov/flapigen-rs?

Thank you, that looks easier to port. I'll take further look into it.
