A tiny 32-bit bare-metal kernel written in Rust that paints the screen red and hangs, serving as a minimal demonstration of OS development in Rust. It is an educational starter project for hobbyist kernel development, requiring QEMU, NASM, and an i386 cross-compiler to build and run.

Use cases

• learn how to write a bare-metal kernel in Rust
• bootstrap a hobby operating system project
• see a minimal freestanding Rust program example
• experiment with boot sectors and QEMU emulation
• understand how Rust can run without a standard library

When to choose

• you want a minimal starting point for Rust OS development
• you are learning low-level x86 boot concepts
• you want a tiny example of freestanding Rust code

When to avoid

• you need a production or maintained kernel
• you want modern Rust toolchain compatibility (it targets Rust 0.7/master circa 2014)
• you need a full-featured OS or driver framework
