The primary design goals of RCore are:

) in fusion energy research, particularly when studying argon seeding in tokamaks .

: Frustrated by the complexity and memory safety issues of traditional C-based kernels like Linux, a group of students and researchers set out to build a "Next-Gen" operating system from scratch using Rust .

However, rcore is not without its challenges. Rust’s strict safety rules, while beneficial for robustness, introduce a steep learning curve. Implementing doubly linked lists or circular buffers—common OS data structures—requires contortions (such as using RefCell or raw pointers) that can distract from the core OS concepts. Furthermore, as a relatively young project, rcore lacks the hardware driver support and ecosystem maturity of Linux or BSD. It is an educational tool, not yet a production server kernel.

The story of rCore-OS is a journey of academic innovation, starting at .
