pyo3-stubgen generates .pyi typing files for extension modules which were written in rust with pyo3.
It is designed to work for extension modules created in rust with pyo3 but should work with any compiled extension
modules which include a __text_signature__ and optionally a __doc__ attribute for functions.
Despite flake8's recommendation to the contrary, pyo3_stubgen adds docstrings to the .pyi files so that IDEs can
provide them in hover pop-ups.
You will need to manually add the typing information to the generated files as this is not included in any of the function attributes available and is just as dependent upon the semantics of your functions as on the technical implementation.
Note: Currently pyo3_stubgen only generates info for functions. Classes are on the to-do list.
Install via pip:
(.venv)/projectroot$ pip install pyo3-stubgenEasiest from the command line:
(.venv)/projectroot$ pyo3-stubgen MODULENAME OUTPUTLOCATIONSee pyo3-stubgen --help for more details
Alternatively via the python API. See the docs for more details.
