AFAIK, the only complete desktop GUI option for Rust that is viable for large, professional apps is gtk-rs. There are many promising up and coming GUIs for hobby projects, but none I've seen are robust enough (yet) to support all needed widgets of a pro app.
Accessibility support is the big killer for many of them, though even GTK has issues with that on Mac OS, so Qt would be a big win.
Or I guess you could put a Rust wasm app into electron also and have accessibility support that way. Has to be one that uses a real DOM and not just renders to a canvas or WebGL though.
Ahh...very cool, thx. Didn't realize it was that capable and was not aware of this "demo". I will check it out as I need to write a GUI soon (and would prefer to use Rust).
There are plenty of GUI solutions that are robust enough for an embedded GUI or some WebAssembly stuff. For native (desktop) applications the rust ecosystem still has a long way to go.
