Operating system interfaces use the C ABI, but they don’t require you to use C.
Actually that’s true on most OSes, but not Linux - that uses syscalls as its interface not function calls to a shared library, so it’s the syscall ABI.
I still feel like designing and bootstrapping your own higher level language is going to be less painful overall than writing a Rust compiler in C. And probably more fun.
