Use c2rust for cleaning up produced bindings

[XVilka]

There is an issue to use c2rust for tranlating inline functions, but if you check the output of bindgen, you can spot some patterns that c2rust also normally works with, so they created an amazing refactoring tool. And it can be scripted with Lua, so some bindgen-specific automation can be easily added without much changes from c2rust side - see their manual for refactoring tool. Sorry if idea is irrelevant, just thought it might be handy.

I think it's interesting, but what kind of refactoring do you want to apply to the generated bindings?

In general bindgen doesn't produce a lot of stuff other than declarations, typedefs, etc, so it's not clear to me what you can or cannot cleanup from them...

Do you have concrete examples or ideas?

I'm not sure refactoring is really needed for the auto-generated bindings. If there's particularly ugly codegen the generator could be fixed, but I'm not sure that's needed. When I've used bindgen I generally never look at the generated code, instead using the C header as API docs.

That said, I'd be happy to look into any particular refactoring that could be useful, if there are any.

It was just a wild idea, you can close if you think it is useless. Sorry for disturbance.

No, no worries at all, it's appreciated :)

Closing as this is not actionable as-is, but feel free to reopen if there's anything concrete that could be done here.
