druid VS femtovg

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.

Femtovg (https://github.com/femtovg/femtovg) which uses OpenGL to render

Congrats! I don't want to diminish the accomplishment, but have you seen femtovg? It seems like it's probably well-aligned with your needs.

I'm currently using femtovg for vector graphics in my games, and I would like to get into bevy by porting one of my game prototypes using it to bevy.

I use femtovg It's a simple vector graphics engine having all the important features you probably want from a 2D rendering engine: simple shapes, images, text

Before Power10 was done, IBM actually asked us Raptor users about proposals for useful machine code instructions to add to it. I replied that I’d like to have hardware UTF-8 de-/encoding but they wanted a more detailed proposal and I never got around to write it. I’m not even sure that this would be worthwhile, but I see UTF-8 de-/encoding everywhere in the code I write and would like it to approach memory read/write speeds.

I was very disappointed to learn that they had gone more proprietary with Power10 so I would not have been able to use those instructions anyway. What a pity!

In my actual code, I'm using a library called femtovg that is a Rust port of a C library for 2D rendering. But In the blog post I kept the example simple to keep it relevant for people who might want to use Web Workers + WASM for other things; didn't want to get hung up on femtovg for someone who had never heard of it. As you say, if you all you need to do is basic 2D manipulations of a canvas that are supported by the native API, then you likely don't need WASM.

You guys should also check out the femtovg project, a 2D rendering API that sixty fps relies on.

It's a decent starting point for trying to build your own toolkit.

I have recently added a wgpu backend but for now it lives in my fork https://github.com/adamnemecek/femtovg

run the demo with `cargo run --example wgpu_demo --release`.

Also join the femtovg discord https://discord.gg/V69VdVu

I'm involved with the femtovg project. We are definitely looking for contributors. Join the discord channel.

It's not a GUI framework but I'm involved with this project called femtovg, it's a Rust nanovg port. I've recently added a wgpu backend. Run the demo with cargo run --example wgpu_demo --release. Some people have been using it for their own UIs, e.g. tuix. I think that you should consider rolling your own GUI toolkit, it's not that bad and you'll appreciate the control.
