A blog series and accompanying source code that teaches how to write a small operating system kernel in Rust, covering freestanding binaries, VGA text mode, interrupts, paging, heap allocation, and async/await. Each post is a step-by-step tutorial with code available in per-post git branches.

Use cases

• learn how to write an operating system kernel in Rust
• tutorial for building a bare-metal Rust kernel
• understand paging and memory management in an OS
• learn how CPU exceptions and hardware interrupts work
• implement a custom heap allocator
• get started with no_std Rust development
• study async/await at the kernel level

When to choose

• you want a guided, step-by-step introduction to OS development in Rust
• you prefer tutorials with complete, runnable code for each stage
• you want to learn bare-metal no_std Rust and QEMU-based testing

When to avoid

• you need a production-ready or general-purpose operating system
• you want a full-featured OS with drivers, filesystems, or userland
• you are not interested in low-level systems programming
