Requires-Dist problems when updating "Nine Rules for Writing Python Extensions in Rust"

[CarlKCarlK]

Background: I gave a talk last week at PyData about creating extensions with Rust with maturin. It was based on the "9 rules" article from last year, I updated versions of Maturin, etc in the bed-reader genomics project after the talk.

I just noticed, however, that the new *.whl's have bed_reader_0.2.33.dist-into/METADATA without "Requires-Dist".

My Cargo.toml and pyproject.toml are in the same (top-level) folder of my project. The pyproject.toml says among other things:

[build-system]
requires = ["maturin==0.14.17"]
build-backend = "maturin"

[tool.maturin]
# https://github.com/PyO3/pyo3/discussions/2271
cargo-extra-args = "--features extension-module"
requires-python = ">=3.7"
requires-dist = ["numpy>=1.13.3", "pandas>=0.25.1", "pooch>=1.1.1"]

Any idea how it lost the "requires" info? If/when we figure it out, I'll update the article (and the project) to help others.

Thanks!

It looks like I need to add:

[project]
name = "bed-reader"
dependencies = ["numpy>=1.13.3", "pandas>=0.25.1", "pooch>=1.4.0"]

instead of requires-dist. Is that right? Is cargo-extra-args still needed?

Newer maturin versions supports PEP 621 so dependencies declaration has been moved to [project] table in pyproject.toml.

cargo-extra-args was removed long ago, please view the migration guide here: https://maturin.rs/migration.html.

Everything seems to be working now. Thanks!
