vizia VS druid

All of these projects have in common that they use Taffy (the project that I work on!) for box-level layout (which currently gives them block, flexbox, and grid layout) , and are either using or planning to use cosmic-text for text/inline layout. This gives you a decent first approximation of web layout, but it's not perfect and there are major features like float, display: inline-block, position: static, box-sizing: content-box missing. Not to mention that none of these implementations currently resolve CSS selectors, so you are effectively limited to inline styles (if you're interested in something in that direction then you may be interested in https://github.com/vizia/vizia).

Vizia is basically fine-grained reactivity with an Elmish twist, though I haven't used it, so I couldn't say how well it works.

There are a number of up-and-coming Rust-based frameworks in this niche:

- https://github.com/iced-rs/iced (probably the most usable today)

- https://github.com/vizia/vizia

- https://github.com/marc2332/freya

- https://github.com/linebender/xilem (currently very incomplete but exciting because it's from a team with a strong track record)

What is also exciting to me is that the Rust GUI ecosystem is in many cases building itself up with modular libraries. So while we have umpteen competing frameworks they are to a large degree all building and collaborating on the same foundations. For example, we have:

- https://github.com/rust-windowing/winit (cross-platform window creation)

- https://github.com/gfx-rs/wgpu (abstraction on top of vulkan/metal/dx12)

- https://github.com/linebender/vello (a canvas like imperative drawing API on top of wgpu)

- https://github.com/DioxusLabs/taffy (UI layout algorithms)

- https://github.com/pop-os/cosmic-text (text rendering and editing)

- https://github.com/AccessKit/accesskit (cross-platform accessibility APIs)

In many cases there a see https://blessed.rs/crates#section-graphics-subsection-gui for a more complete list of frameworks and foundational libraries)

I don't think it's actually merged into Iced yet. It is merged into https://github.com/vizia/vizia though.

Vizia

I have recently learned about https://github.com/vizia/vizia and it looks very promising to me

For GUI applications, the story is mixed. There are several GUI frameworks in active development, but nothing as polished and battle-tested as Electron for TypeScript. There are bindings to GTK, but they're cumbersome to work with, and I wouldn't recommend it to a Rust newbie. There's also Tauri, which is a bit like Electron and lets you write the GUI in HTML/CSS/JS and the business logic in Rust.

Concerning GUI frameworks, the most common ones are druid, egui and iced. All three of them run native and on the Web.

Going to give a shoutout to druid. I've recently tried it with the Lapce editor and it's just so smooth, fast and works so well for a pre-alpha app.

As iced and egui were difficult for me, i started with druid.

There is Iced which is used by system76 in Pop!_OS, Druid [DISCONTINUED], GTK-rs, Relm, Azul and Tauri. Personally I would use Tauri for its speed using the OS's native web render, documentation of use with things such as Sveltekit and the ability to make UI's using JS, CSS and HTML. Tauri similarly to Electron whilst being far faster. But its up to personal preference really. There aren't any solid "go to" options at the moment.

Druid should be good for most cases, it has a lot of built-in widget for the UI, you can even make a custom widget with a canvas-alike painting API.

Druid, which is a Rust-native UI toolkit for building desktop applications targeting Windows/macOS/Linux/OpenBSD/FreeBSD, has a new version out - v0.8.

There's a memoize View node in the previous iteration of the Xilem prototype, but it hasn't made it in to the current branch yet. That sounds like what you're asking, but it's possible I'm missing something.

You can use GTK from Rust. But the Rust native ones aren't really there yet. [Iced](https://github.com/iced-rs/iced) which has been picked up by System76 and [Druid](https://github.com/linebender/druid) (and it's next gen version [Xilem](https://github.com/linebender/xilem)) are the ones to watch, along with Dioxus which is the main post here.

I'd expect there to be something useable by the end of 2023.
