Test `rustworkx` with free-threaded Python #1251

Open IvanIsCoding opened 1 month ago

What is the expected enhancement?

Starting with 3.13, we should test rustworkx with https://py-free-threading.github.io/ to make sure it at least work with a single-thread setting. I don't think we should make our data structures thread-safe (that is a lot of overhead).

Of course this will heavily depend on PyO3 and their API offerings. But so far they have made progress on removing the GIL

And we are blocked until NumPy releases a new version supporting free threaded Python anyway: https://py-free-threading.github.io/tracking/.
