Memory Safety: Prevents common classes of critical security bugs by design.
Modern Tooling: Strong type system and error handling improve long-term reliability.
Performance: Zero-cost abstractions matching traditional C/C++ speed.
Boot Sovereignty: Forms the base of the Trusted Computing Base (TCB).
Deterministic: Tight control of memory layout and minimal runtime footprint.
ASM Primitives: Required for reset handlers and constant-time crypto.
Evolution of Firmware: While C is the standard for ROM, OpenTitan's TockOS ecosystem uses Rust for stable firmware to extend memory safety directly into silicon layers.
