How to Migrate From C/C++ to Rust: A Practical Guide for Embedded IoT Systems

Embedded and IoT devices operate in environments where every kilobyte of memory and every millisecond of response time matters. Yet most of them still rely on C or C++, languages powerful enough for low-level control but notorious for memory-safety flaws that can crash systems or expose them to security vulnerabilities. The issue is so widespread that around 70% of Microsoft’s and Google’s reported vulnerabilities stem from memory-safety issues.
