I'm writing my first Rust-based Python module, and it kills the Python process on import. I've got it down to a pretty minimal example, based loosely on the html-py-ever example (which does run for me without crashing).
I'm running Python 3.8 on an M1 macbook, Python is compiled for arm64.
% python -c "import platform;print(platform.machine())"
arm64
My output, reproducer command using the files pasted below. The install should take care of any python requirements:
(rust) jeremytemp@Jeremy-McGibbons-MacBook-Pro minimal % pip install -e . && python test.py

What am I doing wrong? Are there any steps I can take to get more helpful debugging output than "killed"?
