Integrating Rust with handwritten assembly presents a security paradox: while Rust enhances C code safety, inline assembly can bypass these protections by allowing arbitrary memory jumps. Jean-Baptiste proposes 'secure assembly' through compile-time instrumentation (like checkasm) to validate assembly code, ensuring it doesn't compromise the overall security model, especially when performance demands necessitate its use.
Impact: High. This highlights a critical, often overlooked, challenge in modern systems programming where performance-driven assembly can undermine the safety guarantees of languages like Rust. It points towards necessary innovations in compile-time verification for hybrid codebases.
