GNUI

GNUI (pronounced /ʒe.ɛn.y.i/) is a high-performance, modern alternative to GTK, designed specifically for GNOME. It is built from the ground up in pure Rust to provide the "Adwaita" look and feel without the legacy baggage of C, GObject, or complex FFI bindings.

Motivation

Developing GNOME apps with gtk4-rs often feels like fighting the tool rather than building the app. The numerous C dependencies bring exhausting issues when bound to Rust. GNUI and its dependencies are full Rust, and directly usable in your project using one simple import.

Thinking of a Rust-native framework for GNOME also brought the opportunity to make the library more "rusty": easier and more intuitive.

Why not use Iced or Slint?

GTK is at the core of GNOME's UI experience. Iced and Slint both come with specific design choices that don't match GNOME's environment. GNUI comes by default with libatawia's look, and displays native-looking GNOME components.

Installation

# yeah, it's that simple
cargo add gnui

Quick example

Use a declarative approach that feels natural in Rust.

fn view(state: &AppState) -> Element {
    Column::new()
        .padding(12)
        .spacing(8)
        .add(
            HeaderBar::new()
                .title("My App")
                .show_close_button(true)
        )
        .add(
            Button::with_label("Click Me")
                .accent_style()
                .on_click(Message::Increment)
                .border(2.0)
        )
}
