Inspiration

This project is fueled by our curiosity to deeply understand how systems work under the hood.
We aim not only to build but to truly understand every piece of the stack — from booting the hardware to managing processes and memory.

About the Project

Rust OS is a fully handcrafted operating system project, built completely from scratch using the Rust programming language.
We have successfully completed all major components of the blog_os tutorial and are now taking the next steps: extending the OS with advanced features like a basic graphical interface and a simple filesystem.

Our journey so far:

Bootstrapped with a custom bootloader
Set up memory management (heap, paging)
Implemented interrupt handling and basic multitasking
Built dynamic memory allocation without a standard library
Added process/task switching and timer interrupts

Current Focus

We are now extending the operating system with:

🖥️ Basic GUI: Framebuffer graphics, simple windows, mouse cursor
📂 Simple Filesystem: In-memory filesystem with basic file operations

Tech Stack

Language: Rust
Bootloader: bootimage
Tooling: QEMU for virtualization, Cargo for building
Architecture: x86_64, arm (coming soon)
Framework: no_std environment
