Pushed an edit to this that: - Uses `Uuid` and custom type handling as the example. I think this is closer to a real-world scenario. - Added an option for...

Yeah, that's what I'm thinking as well.

I don't think I ever implemented that. When I wrote up #1747 I needed to [write some code to workaround the differences](https://github.com/mozilla/uniffi-rs/pull/1747/files#diff-bff922c65ef3007e6164f74d62c32454769b177527c7a53b29dae9075edfbafaR155-R162). UDL has never supported it. There was a...

It makes a lot of sense to me as well and also reminds me of the Firefox JS work. That ended up working out, so I think this effort could...

Makes sense to me, excited to see how this progresses. I don't think there's anything fundamentally hard about callback interfaces, it's just felt like they're a lot of work to...
