That does sound really nice - would love that with Tauri.

I've never used Typescript, so at the moment I just have the pain of untyped structures in JS-land (and making sure I get it right passing back in to Rust-land) - but, at least as far as I know, if I did use TS I'd just suffer from manually duplicating data structures instead.

(I suppose ultimately I intend to do that, it's just so imperfect anyway that I haven't bothered yet.)
