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.
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
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
- Language: Rust
- Bootloader: bootimage
- Tooling: QEMU for virtualization, Cargo for building
- Architecture: x86_64, arm (coming soon)
- Framework: no_std environment
Prerequisites: Rust nightly, QEMU, bootimage
# Install Rust Nightly
rustup override set nightly
rustup component add rust-src
# Install bootimage
cargo install bootimage
# Build the OS
cargo bootimage
# Run it using QEMU
