Getting Something for Nothing
summary
Rust uses the type system and borrow checker to push hardware safety to compile time, modeling memory-mapped peripherals as singletons and typed state transitions so mutable aliasing is impossible. Tools shown include svd2rust for auto-generating register bindings, cortex-m singletons/RTFM for safe ownership, and embedded-hal traits for reusable drivers. Examples target nRF52-class microcontrollers with ~20–64 KB RAM and tens–hundreds MHz CPUs; abstractions are zero-cost (via zero-size types), generate no runtime overhead, and are already working in the ecosystem.
