Karg is the kernel of CargOS. It abstracts the low-level interfaces of devices and implements the core functionalities of the system. Essential features such as process management, I/O management and file system are all provided by it.
We tried, initially, but encountered numerous quirks and inconveniences. For instance, it lacks support for essential low-level structures like anonymous unions, contains numerous nightly features, and adheres to conventions that aren't appropriate for a single-core kernel. Additionally, the requirements of its standard traits are way too strict. Despite these issues, Rust remains a viable option for user space programs.
