Right, Rust is more complex, and it is the complex bits that make it Rust. There are sure some shortcuts possible for starters, for example scope-based lifetimes like in early Rust versions, but still, to make it a worthwhile upgrade over C, it would take some intermediate representation, and definitely more than 700 lines.

There is a lively movement for coding in Rust for esp32, that works, just not on the device I think.

I would love to see something like C with a borrow checker and Result/Option but not the fancy type system.

The big question is whether or not that is even possible. My money is on 'no'.
