Given that the last commit is by someone with the same username as you, wouldn't you know better than random HN commenters?

Well, that's the thing. In my (biased) opinion, that crates doesn't have any of the problem mentioned.

- The qmetaobject crate tries to be idiomatic rust and to be used without any C++

- As far as the user is concerned, there shouldn't be any call involving C++

- It does follow the Rust multi-threading guarantees

- The License is the same as CXX-Qt

- It does support plugins: https://github.com/woboq/qmetaobject-rs/tree/master/examples...

- It uses code generation via macro

so say that, instead of playing this fake "oh I don't know and have nothing to do with it, can anyone help" game. Know your audience. It's HN, mentioning your alternative is accepted here as long as you're fair and honest about it, especially since this isn't even a Show HN.
