How to implement coverage properly on a mixed project: Python + Rust

[andresliszt]

Hello! Thanks for this amazing project. I'm working on a project with python + rust using pyo3. When I do pytest i'd like to catch the rust code executed through python. I haven't found any documentation in the web. Do you have an official doc to do it?

Thanks again

This isn't really a pyo3 question, it's a rust coverage question, so mostly you follow the rust coverage documentation: You can look at https://github.com/pyca/cryptography for an example of this (the relevant bits are in noxfile.py and ci.yml).
