⚡ RUSTED UI

✦ ZERO GC ALLOCATION | ✦ RUST TAFFY ENGINE | ✦ 10 LIVE THEMES | ✦ STEAM DECK VERIFIED

🌟 What is RustedUI?

RustedUI is an ultra-fast, zero-lag in-game user interface framework and visual showcase for Stardew Valley 1.6+.

Traditional UI mods in C# frequently suffer from garbage collection (GC) micro-stutters and frame spikes when drawing detailed menus or telemetry overlays. RustedUI eliminates this completely: by calculating all layout, styling, and text wrapping inside an embedded, compiled Rust engine (powered by Taffy v0.7 Flexbox & Grid) with arena memory and 0 bytes of C# garbage collection per frame, it outputs raw MonoGame SpriteBatch draw calls in microseconds (~0.03–0.08 ms).

Whether you are a player who wants clean, customizable HUDs and menus that match Stardew Valley's art style, or a mod author looking to build interfaces using HTML, Tailwind CSS, React/TSX, or C# Fluent Builders, RustedUI is built for you!

✨ Key Features

• 🦀 Zero Garbage Collection Overhead: Smooth 60/120+ FPS gameplay with 0 bytes of managed C# allocations during rendering.
• 🎨 10 Instant In-Game Themes:
  • Pelican Classic: Authentic vanilla Stardew Valley wooden and parchment 9-slice boxes.
  • Shadcn Zinc Dark: Sleek modern dark mode (#09090B / #18181B).
  • Wizard Arcane: Mystic deep violet and starlight gold.
  • JojaCorp Blue: Corporate industrial cobalt and cyan.
  • Junimo Forest: Organic emerald and dewdrop green.
  • Catppuccin Mocha, Tokyo Night, Dracula, Nord & Cyberpunk Neon: Highly requested community palettes!
• 💬 Theme-Aware Floating Tooltips: Hovering over any HUD element or item slot shows an interactive tooltip styled to match your selected theme.
• 🔒 Per-Mod Theme Isolation: Third-party mods keep their own custom branding without being overridden by global theme changes (unless explicitly opted in).
• 🎮 Steam Deck & Gamepad Verified: Seamless controller support, full-screen UI scaling, and proton compatibility with no third-party overlay hooks.
• 📦 Built-In Widget Catalog: Item slots with quality stars, dynamic friendship heart meters, gold counters, progress bars, text input with keyboard support, smooth sliders, and hardware-clipped scroll views.
• 📐 Modder-Friendly Workflows: Build menus using HTML + Tailwind CSS (with live in-game hot-reload), React/Vite TSX ahead-of-time components, or a type-safe GPUI-style C# Fluent Builder.
