What do people build with it?

USE CASE 1

Write graphics code once in Rust and run it across Windows, Mac, Linux, mobile, and web.

USE CASE 2

Build a cross-platform game or visual app without learning Direct3D, Metal, Vulkan, and OpenGL separately.

USE CASE 3

Add WebGPU-powered rendering to a browser application via WebAssembly.

USE CASE 4

Use compile-time safety checks in Rust to avoid common graphics bugs like memory corruption.
