WaterUI 🌊

A cross-platform UI framework for Rust with cross-platform native rendering

Counter example

use waterui::prelude::*;

pub fn counter() -> impl View {
    let count = Binding::int(0);
    let doubled = count.map(|n| n * 2);
    
    vstack((
        text!("Count: {count}"),
        text!("Doubled: {doubled}")
            .font_size(20)
            .foreground_color(Color::gray()),
        
        hstack((
            button("Increment")
                .action_with(&count,|count| count.increment(1)),
            button("Reset")
                .action_with(&count,|count| count.set(0))
                .foreground_color(Color::red()),
        ))
        .spacing(10),
    ))
    .padding(20)
    .spacing(15)
}

✨ Features

• True native rendering - Uses SwiftUI on Apple platforms (yes, even visionOS/watchOS/widgets!)
• Vue-like fine-grained reactivity - Allows efficient updates without virtual DOM
• Type-safe from top to bottom - Leverage Rust's type system fully
• Declarative & reactive - Familiar to SwiftUI/React developers
• Cross-platform - Supports multiple backends (gtk4 backend and swiftui backend are ready now)
