RUST Meets Embedded Linux: Build Memory Safe and Reliable Kernel Modules, Applications
summary
Linux mainline is at Linux 6.x with optional CONFIG_RUST support; the rust/ directory in 6.16 is about 182 files (~47,000 lines), so kernel Rust is usable but incomplete. You can build a Rust hello module with a normal Makefile, need clang/LLVM, and many kernel APIs still require wrappers or fall back to C. Userland uses cargo for cross‑compiles, FFI via .a/.so, debug with GDB/rust‑analyzer, and packaging via Yocto recipes.
