Information

• rustworkx version: 0.13.0
• Python version: 3.7
• Rust version: N/A
• Operating system: Linux

What is the current behavior?

Running mypy with Python 3.7 in a package that uses rustworkx fails trying to parse the stubs files. For example:

/opt/hostedtoolcache/Python/3.7.16/x64/lib/python3.7/site-packages/rustworkx/graph.pyi:34: error: invalid syntax  [syntax]

See: https://github.com/qiskit-community/qiskit-nature-pyscf/actions/runs/5200238443/jobs/9378913497?pr=35#step:7:15 for where this happened in CI.

What is the expected behavior?

The type hint syntax used is compatible with the rustworkx python version

Steps to reproduce the problem

Run mypy using rustworkx on python 3.7
