Slint VS rust-sciter

As an anecdote, the three top contributors to sixtyfps are ex-Qt people. I think it is not anecdotal that there is at least some degree of overlap and competition between Rust and C++, and that this is a market that surely The Qt Company is watching.

SixtyFPS (https://sixtyfps.io/) is in progress for Rust, but it is still early days. It also does not technically use a native toolkit (it uses Qt), but I believe that might be on roadmap. For traditional GUI apps, I think the lack of a table or tree widget is the most limiting for the time being. They have stated they intend to remedy that.

The most promising GUI hasn't been posted here, SixtyFPS. It's in it's early stages and not FOSS, but it's built by some ex-QT cats and has a lot of potential.

People have been recommending https://sixtyfps.io/ to me.

There is already a project to make a Qt like GUI toolkit in Rust: https://sixtyfps.io/ It is really similar to Qt https://sixtyfps.io/releases/0.1.5/docs/rust/sixtyfps/index.html

People are doing that too. https://sixtyfps.io/ is basically a Qt clone in Rust, actually developed by previous Qt developers.

spdlog, a pretty useful and more and more commonly used logging library for C++.\ SixtyFPS, an emerging GUI library for Rust, but you can use it in multiple languages. It uses OpenGL or Qt currently as backend (well, it's a new library and they wanted two from the get-go to make sure their abstractions are done right/well enough). They started a company this year for it too.

Just so some are not aware, there's a new project called sixtyfps by some people who were in the Qt world for long. I didn't take a deep dive into it but it looks promising.

Most GUI apps don't need what Qt provides though. They mostly need stability and cross-platform support, so ... they should start with something like Tauri or Sciter, and if there is something they need natively they will be in a much better situation to pick their poison.

https://github.com/sciter-sdk/rust-sciter uses Sciter

I seriously advise against using rust-sciter. It uses a lot of unsafe code, some of which is invalid and directly causes Undefined Behavior; see for example issue #114. rust-sciter's author doesn't seem to have any interest in fixing those. Besides, the code is highly unidomatic and looks like it's been written to resemble C++ – this is in itself not wrong, but always a red flag.
