Thank you. For reference, the following command works in a Flatpak:

. /usr/lib/sdk/rust-stable/enable.sh && cp /app/whl_tmp/tomli-2.0.1-*.whl . && cp /app/whl_tmp/maturin-1.2.3-cp310-cp310-*.whl . && pip3 wheel --verbose --exists-action=i --no-index --find-links=\"file://${PWD}\" --config-settings build-args='--offline' \"./rpds_py\" -w /app/whl_tmp```

It must be noted that Maturin and tomli must be pre-built in a preceding module, because maturin itself currently needs to be patched due to PyO3/setuptools-rust#363
