Embedded Rust or C Firmware? Lessons from an Industrial Microcontroller Use Case | Hacker News

A side-by-side industrial firmware project found Rust matched C in hardware performance and memory use on microcontrollers.

The results suggest Rust is a practical option for embedded development, including resource-constrained industrial systems.

A Rust runtime also showed a smaller footprint than a conventional bare-metal C stack in the comparison.

Discussion then shifted to whether Rust’s compiler, Cargo.lock, and crate ecosystem can stay stable enough for long product lifecycles.
