ViewKit

ViewKit provides the same Rust and C UI runtime on mochiOS, Linux, and Windows. The repository is self-contained for desktop builds: Linux and Windows use the shared winit/softbuffer backend and fonts installed on the host system. Linux supports both Wayland and X11.

Use from Rust

Add ViewKit directly from its Git repository:

[dependencies]
viewkit = { git = "https://github.com/mochiOS/ViewKit.git" }

Then create an application:

use viewkit::prelude::*;

struct Hello;

impl App for Hello {
    type Body = Text;

    fn new() -> Self {
        Self
    }

    fn window(&self) -> WindowOptions {
        WindowOptions::new("Hello ViewKit").size(640.0, 400.0)
    }

    fn body(&self, _context: &ViewContext) -> Self::Body {
        Text::new("Hello from ViewKit")
    }
}

fn main() -> Result<(), ViewKitError> {
    viewkit::run::<Hello>()
}

Run it normally on Linux or Windows:

cargo run

Build this repository

cargo build --release
cargo run --example button

Generating the C header additionally requires cbindgen:

cargo install --force cbindgen
./scripts/generate.sh

mochiOS builds

mochiOS has no system font service, so its build supplies font files explicitly through VIEWKIT_UI_FONT_PATH and VIEWKIT_MONOSPACE_FONT_PATH. Desktop users do not need these variables or the surrounding mochiOS source tree.
