Setuptools is creating is creating egg for UNKNOWN instead of setuptools-rust
I'm trying to build setuptools rust (v1.3) using python 3.10.4, openssl 3.0 and setuptools v58.2 These are the commands and outputs:

I'm not sure why setuptools is building it for unknown and not setuptools-rust. Could someone please point to my mistake?

We need to see pyproject.toml, setup.cfg, and setup.py to be able to help.

Thanks for your interest! I've added the relevant files, please check

Right... the configuration files seem correct. I now noticed that the current working directory is not the directory containing the setup.py script, and I guess that is the reason why. You probably should move to the directory containing the setup.py before running setup.py commands.

That worked! Thank you so much, I didn't know that it mattered which folder I called setup.py from.

The issue seems to be that your current working directory has to be the directory containing the setup.py script. As far as I can tell anything like python path/to/setup.py will fail, and only python setup.py will succeed. So first cd into the project directory containing the setup.py script, then call setup.py commands.
