winit VS druid

Hi! I’m Aloke, an engineer at Warp.

I’m really excited to share that Warp is now available on Linux! If you’re interested in trying it out, you can download Warp: https://warp.dev/

Building Warp on Linux was quite an undertaking. Warp uses a custom Rust-based UI framework that we built in house and renders natively on the GPU. To get Warp running on Linux, we built a version of our UI framework that supports winit [1] as a windowing backend. We also built a version of our renderer that uses wgpu [2]. Reducing complexity by using these well-supported, cross platform, frameworks let us bootstrap a version of Linux quicker than expected and should make it easier to build Warp for other platforms (like Windows).

Please let me know what you think! Happy to answer any questions, either about the product or about technical challenges.

This link: https://github.com/rust-windowing/winit has this code:

Have you seen the official example?

That's a bit shortsighted given that there is an active discussion about reducing the interior mutability.

I really need a file dialog for my ImGui-based project in Rust. I tried using this crate but it's wayyyyyyy too old. I also saw this but considering the date it was last updated and the look of the repo, it's not gonna work either. Also I maintain my own library for such things, but it's currently blocked by this issue. What options do I have?

In this case, I used the "A"GPL because this crate could feasibly run on the web. winit has a web backend. At the moment I don't support it (there's a PR that needs to land first), but in the near future it's not implausible that this crate could be used in a web environment.

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)

It uses a forked version of Druid. https://github.com/lapce/druid which replaces the window management to use winit instead https://github.com/rust-windowing/winit
