mirui

A lightweight, no_std ECS-driven UI framework for embedded, desktop, and WebAssembly.

Features

• ECS architecture — every widget is an entity, styles and state are components, layout and rendering are systems
• no_std + alloc — runs on bare-metal MCUs (STM32, ESP32) with a global allocator
• Pluggable render backends — SDL2, framebuffer, WebAssembly Canvas, or bring your own
• Flexbox + absolute positioning — familiar layout model
• Dirty-flag driven — only re-renders what changed

Quick Start

• Minimal ECS core
• Layout engine (Flexbox)
