rust-dominator VS druid

They are both async and made for GUI -- in case of rust-signals WebGUI, provided by dominator and MoonZoon.

You shouldn’t ever need to deal with OsString itself on wasm32-unknown-unknown, since that target basically just doesn’t cover functionality that needs it, but the actual situation is genuinely worse than OsString: Rust insists on valid Unicode (as is right and proper), but the web suffers from the affliction of ill-formed UTF-16. If you blindly convert from JavaScript strings to Rust strings, you will encounter data and functionality loss in a few situations, in practice always involving IME (or similar) text entry on Windows. The first bug I filed about this: https://github.com/Pauan/rust-dominator/issues/10, and you can follow further links if you’re interested. IE and Edge used to be largely immune to this, but IE is dead and I suppose Edge will have regressed in this way with the Chromium migration, since the bug filed in Chromium a few years ago <https://bugs.chromium.org/p/chromium/issues/detail?id=949056> has languished. (Firefox too, with <https://bugzilla.mozilla.org/show_bug.cgi?id=1541349>.) In the worst-case scenario, careless use like was the case in rust-dominator will mean that some users typing with particular software in a language that’s outside the Basic Multilingual Plane will not be able to type anything.

One comparison I'm missing , which I think provides quite a nice solution in Rust, is the signals based approach popularized by Solid JS and implemented in Rust by sycamore and earlier by dominator.

Missing support for characters beyond U+FFFF is the main problem caused by surrogates (their existence, even if indirect)—it normally comes of some kind of UCS-2/UTF-16 confusion. It’s not fair to disqualify them. The only (class of) case that I’m aware of for a long time where it’s not linked to that is with MySQL’s idiotic utf8 → utf8mb3 type.

You may not have encountered such bugs, but I’m very familiar with surrogate-related bugs, because I use a Compose key extensively. I haven’t been using Windows for the last year, but from time to time I would definitely encounter bugs that are certainly due to surrogates. On the web, I found bugs a few times, all but once in Rust WebAssembly things, such as https://github.com/Pauan/rust-dominator/issues/10. And even now I’m back on Linux, I know of one almost certainly surrogate-related bug: I can’t type astral plane characters in Zoom at all; pretty sure I had this problem back on Windows, too. Copy and paste, sure, but type, no, they become REPLACEMENT CHARACTER.

The history is unfortunate but I strongly refute that they had not much choice. UCS-2 should have been abandoned as a failed experiment. Certainly there had been significant investment into it in the last few years, but with the benefit of hindsight, switching to UTF-8 (which was invented before they decided on surrogates) would have made everyone’s life much easier, especially given its ASCII-compatibility.

Ah, BOM characters. Haven’t seen one in years. Good riddance.

I really don't understand why everyone jumps to Yew when it comes to front-end development. Dominator is a far cleaner and more Rust-orientated approach to building front-end apps. I have worked with both and I feel that Yew adds a lot complexity/forces a lot of design philosophies but gives very little back in terms of advantages.

Hi, I've just released a major new version of Silkenweb. It's a signals based web framework like Dominator or Sycamore, but with the emphasis on plain rust syntax rather than a macro DSL.

Check out the alternatives without vdom, especially Dominator https://github.com/Pauan/rust-dominator. It’s faster than nearly all JS frameworks. The underlying rust-signals it’s based on is a fantastic crate. Unfortunately it’s not very well documented (check the prs for some wip docs). I got a frontend up and going with reactivity and nice styles using trunk and tailwindcss with daisyUI very quickly.

How does this compare to dominator?

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.
