Self-contained wheels with no dependency on cargo for installation

[cswinter]

I have a Python package published to PyPI with maturin: https://github.com/entity-neural-network/ragged-buffer
Users are running into errors about cargo missing when installing the package. Is there a way to publish a package that does not have any install or runtime dependencies on cargo?

I see you already published binary wheels for that package, so the users running into errors about cargo missing may use an outdated pip. Upgrading pip should resolve the issue.
