vtebench VS druid

https://github.com/alacritty/vtebench/tree/master

Hey - that's a good point. The thing about terminal benchmarks is that there are many of them, each focusing on a different aspect and producing different results. There's one by alacritty team[1] that we used in our initial tests[2], there's another ones mentioned in the comments above etc. When using vtbench, Warp performed much better than iterm, for example.

Ideally we'd ace all of them, but we're not there yet. Anecdotally, many of our users mention speed/performance improvements over other terminal apps a lot in our Discord!

The diagram below shows the output of vtebench for scrolling in various terminals. For some reason Hyper generally could not handle running the benchmarks at all and did not terminate after a reasonable amount of time.

It's not easy to measure the performance of terminal apps. But I definitely notice a difference compared to let's say iTerm2, especially when scrolling through large files in Vim. Alacritty claims that it's faster than the competition using vtebench as a benchmarking tool. Kitty claims that the CPU usage is slightly increased compared to xterm (6-8% compared to 5-7%), but that scrolling is smoother.

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.
