## What it is
Glium is a safe, high-level OpenGL wrapper library for Rust that sits between your application and the raw OpenGL API. It enforces Rust idioms like RAII and stateless function calls while handling error-prone OpenGL details such as framebuffer objects, samplers, and vertex array objects automatically.

## Use cases
- render 2D and 3D graphics in Rust without raw OpenGL calls
- write a game or graphics demo in Rust with a safe OpenGL API
- avoid OpenGL crashes and errors from API misuse
- manage vertex buffers, framebuffers, and shaders in Rust
- learn modern OpenGL techniques through a Rust-friendly API
- set up an OpenGL context easily with glutin integration

## When to choose
- you want to use OpenGL from Rust with memory and state safety guarantees
- you prefer a stateless, RAII-based API over raw OpenGL's global state machine
- you need compatibility across many OpenGL versions with a unified API
- you want automatic handling of FBOs, VAOs, and samplers

## When to avoid
- you need a full game engine with scenes, physics, or asset pipelines built in
- you want actively developed cutting-edge graphics features, since the original author has stepped away and maintenance is community-driven
- you prefer Vulkan, wgpu, or other modern graphics APIs instead of OpenGL
- you need guaranteed long-term support from a dedicated maintainer team
