## What it is
rui is an experimental declarative GPU-rendered UI library for Rust, inspired by SwiftUI. It uses reactive state-driven re-rendering with no retained view tree or DOM diffing, built on winit/wgpu and the vger renderer.

## Use cases
- build a desktop GUI app in Rust with a SwiftUI-like API
- render GPU-accelerated custom shapes and canvas drawings
- create reactive UIs where views re-render on state change
- prototype cross-platform Rust interfaces for macOS, Windows, Linux, and iOS
- draw gradients, circles, and custom graphics with a canvas API
- build simple interactive widgets like counters, buttons, and sliders

## When to choose
- you want SwiftUI-style declarative ergonomics in Rust
- you prefer a minimal, simple implementation over heavyweight widget toolkits
- you need GPU-rendered UI with a canvas for custom drawing
- you're building an app like Audulus and want reactive, no-DOM rendering

## When to avoid
- you need a production-stable, mature UI toolkit with a full widget ecosystem
- you require accessibility support or complex retained-view features
- you need a DOM-based or web-technology UI
- your project depends on long-term API stability, since the library is experimental

## Facets
- artifact type: library
- maturity: experimental
- function: ui-components, frontend-framework, graphics
- domain: web-development, developer-tools, cross-platform
- platform: rust, windows, wasm
- tags: declarative-ui, gpu-rendered, swiftui-inspired, immediate-mode, wgpu, reactive-ui, macos, linux, ios
