## What it is
Piston is a modular game engine written in Rust, providing core libraries for windowing, event handling, and 2D graphics with a backend-agnostic design. It uses generics and traits so backends are plugged in at the application level, following a Model-View-Controller pattern.

## Use cases
- build a 2D game in Rust
- create interactive graphical applications
- make a game with a modular backend-agnostic engine
- prototype game mechanics with a lightweight Rust engine
- render 2D graphics with a window and event loop
- build a Minecraft-like client or sprite animation tool

## When to choose
- you want a modular, minimal Rust game engine with a 'less is more' philosophy
- you need backend-agnostic 2D graphics and input handling
- you prefer composing small libraries over a monolithic framework
- you are building long-lived Rust codebases with low maintenance costs

## When to avoid
- you need a full-featured engine with built-in editor, physics, and asset pipeline like Unity or Godot
- your project is primarily 3D and needs high-level 3D tooling
- you want a large community with abundant tutorials and assets
- you need a non-Rust language

## Facets
- artifact type: framework
- maturity: stable
- function: game-engine, graphics, gui, image-processing
- domain: graphics, cross-platform
- platform: rust, cross-platform
- tags: 2d-graphics, modular-architecture, backend-agnostic, event-loop, windowing, game-development
