It might make sense to wait until GitHub Actions are set up, to be more certain these changes don't break anything.

Thanks for the PR. We'll wait until #93 and #89 are merged. That way we'll know if the updated bindings changes anything and if the CI catch anything weird.

[faern]

The new bindings have been merged. So if you want to you can rebase this on top of main and try it out and see if it works locally for you and if the automatic tests pass.

[faern]

All the CI stuff has been merged! Feel free to rebase again and I'll merge if it passes.

Nice! I went ahead and updated this branch, although it looks like this PR needs maintainer approval to run the CI checks.

I was a bit afraid it would turn out like this with the new bindings. The new bindings generate actual Rust enums for the anonymous C enums, not just ints. This has the benefit that related constants are grouped and a bit stricter typed. But the downside is that they must be cast to be used as integers again.

I don't think we can merge this?

[hamirmahal]

Ah, I understand. I'll go ahead and close this.
