Can Rust Replace C in Embedded Firmware? An Industrial Study from ST and Academia
A ten‑week side‑by‑side study by ST, Inria and university researchers shows that Rust firmware for an STM32U585 microcontroller uses 45 % less RAM than an equivalent C implementation while matching performance, highlighting Rust's zero‑heap model, portability advantages and the remaining limitations for low‑end MCUs.
