Slint
Slint is a toolkit to efficiently develop fluid graphical user interfaces for any display: embedded devices and desktop applications. We support multiple programming languages, such as Rust, C++ or JavaScript. [Moved to: https://github.com/slint-ui/slint] (by sixtyfpsui)

Slint VS slint - a user suggested alternative

Will Qt support the Rust language by default? (just curiosity)
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.

BeeWare – write Python, run as native everywhere
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.

What are the best GUI libraries for a potentially “serious”/large project?
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.

Is there a reliable and documented GUI library out there?
People have been recommending https://sixtyfps.io/ to me.

Is it worth writing a GUI toolkit in Rust?
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

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

I'm giving out microgrants to open source projects for the third year in a row! Brag about your projects here so I can see them, big or small!
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.

Why I choose Electron even when I wanted to use QT
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.

Cosmic Alpha Released
Based on [1] it looks like System76 does actually think about accessibility, but it's not upstreamed yet.

Cosmic: A New Desktop Environment
AFAICT the "big deal" here is using a rust-native toolkit, iced[0], rather than just slapping together another reskinned gtk-based solution like most similar submissions do.
So this is potentially a really cool thing, not just somebody tinkering with UI elements.

Building Zerocalc, part V - Iced UI, subscriptions, and code release!
In the last part of the series, we will build a simple UI for Zerocalc. We will use the Iced GUI library as it has a very nice API and very poor documentation which is a great opportunity to dig into its internals...

I am not yet ready to switch to Zig from Rust
It's not actually a limitation, the ecosystem is just young:
https://github.com/iced-rs/iced
My general point though is that there's still some ecosystem/legacy reasons to stick with C++, but Rust very much fills the same niches as C++.

Show HN: Castiron – Simple podcast player in Rust
Hi all!
Castiron is a super simple podcast player/manager I am building to learn Rust. It uses the iced [https://iced.rs/] GUI library.
Currently the feature set is pretty slim, but you can:
- Cosmic Desktop Is Slated to Debut with Pop _OS 24.04 LTS
What are some alternatives?
When comparing Slint and iced you can also consider the following projects:
egui - egui: an easy-to-use immediate mode GUI in Rust that runs on both web and native
gtk4-rs - Rust bindings of GTK 4
slint - Slint is an open-source declarative GUI toolkit to build native user interfaces for Rust, C++, JavaScript, or Python apps.
druid - A data-first Rust-native UI design toolkit.
tauri - Build smaller, faster, and more secure desktop and mobile applications with a web frontend.
