Proposal: Enhanced Rust-Python Exception Interoperability

[zhanyi136]

Thanks for the effort and fantastic work on the library!
I was thinking about the error handling between the Rust core and Python layer. I was wondering if there's a roadmap to more seamlessly connect exceptions from both sides? For instance, making a Rust panic raise a corresponding Python exception with a clear stack trace.
This is just a thought, but I believe it would make debugging much more intuitive. Curious to hear your perspectives!

That would definitely be nice to have, but there are some technical challenges. The Python interface is built for being used in Numba, which has very limited error handling capabilities. Do you have any specific technical proposal for addressing it? Additionally, Rust side panics mostly only occur under exceptional cases. What kind of issue did you encounter?
