From someone who has been interested in Rust for a long time but is only now really getting into it due to time constraints, why do you consider Rust too complicated to replace C? From what cursory knowledge I have, Rust maintains both a bare bones standard library suitable for embedded work as well as a more fully featured standard library that is built on top of that minimal library. What features would keep Rust from becoming a new C other than possibly some issues with ABI stability that from my understanding people are working to resolve?
