Hey, is there a consensus on this from the maintainers? I’d be willing to look into this.

[mhammond]

I don't know if any of the maintainers have thought this through as the need hasn't come up in our use-cases. I suspect the answer will depend on the implementation - ie, how much complexity/overhead it adds vs the current scenario of just using namespace functions.

[ernestask]

Given that constructors are implemented through class/static/whatever methods and that Web IDL does have a concept of static operations, maybe there wouldn’t be a lot of novel code.

I vote for this. It would be great if I could use #[uniffi::export] attribute on static methods.

I also vote for this, it's a limiting factor in my current project.
