Tox, PyTest, sdist...requires usedevelop for idiomatic tox tests to work

[fafhrd91]

I am not very familiar with tox. if you know where to add hook or when, it'd helpful.

regarding wheel, "python setup.py build_wheel" should just work.

I'm sure I know significantly less than you about setuptools' interfaces and options. :) It's not an essential "feature" anyway, but it was something I encountered that might be relevant to others.

Glad to hear that wheel-building should work OK out of the box. The only platform I care about, really, is Linux x86_64; ARM/ARM64 would be nice, though, so I may investigate how cross-compiling binary wheels would work, also. It looks like Python3 has support for importing platform-specific binaries (e.g. filenames like foolib.cpython-35m-x86_64-linux-gnu.so import successfully as import foolib), so perhaps just cross-compiling manually with cargo and stuffing them in the wheel will work? :)

A bit of necrobumping for people who may read this now: sdist is supposed to get your sources, so no compilation is involved. Compilation is going to happen when you pip install the source distribution sdist creates.

You need to make sure all your Rust sources are embedded in the source distribution using a MANIFEST.in configuration file, because they will not be by default (Python is not aware of Rust sources). When done right, tox should work without the usedevelop option.
