Mobile platform layer for GPUI — run Rust UI apps natively on iOS and Android.
Implements the gpui::Platform trait for mobile targets, following the same architecture as Zed's desktop platform crates.
| Platform | Renderer | Text |
|---|---|---|
| iOS | Metal via wgpu | CoreText |
| Android | Vulkan/GL via wgpu | cosmic-text + swash |
Highlights: GPU-accelerated rendering, touch input with momentum scrolling, keyboard support, safe area insets, dark mode, and emoji rendering.
This fork publishes as gpui-pre-mobile and uses the crates.io GPUI snapshots
from GPUI Kit. Version 0.1.0 targets gpui-pre and gpui-pre-wgpu 0.3.4.
Both are pinned together so the platform, renderer, and application share the
same GPUI types. No Zed Git checkout or consumer Cargo patches are needed.
[dependencies]
gpui = { package = "gpui-pre", version = "=0.3.4", default-features = false }
gpui-mobile = { package = "gpui-pre-mobile", version = "0.1.0" }The Rust library name remains gpui_mobile, including its native library
filenames. Existing use gpui_mobile::... imports continue to work. Native app
entry points and build steps are demonstrated in example/.
This is an experimental platform release. Switching to gpui-pre does not
complete mobile IME composition, accessibility, or the mobile lifecycle hooks.
