A comprehensive guide to hardening Rust code for production environments. Covers panic semantics (unwind vs abort, thread vs process-level failures), panic hooks for observability and sensitive data sanitization, stack overflow prevention, differences between debug and release builds, supply-chain security with cargo-audit and cargo-deny, secure memory allocation with mimalloc, runtime attack surface reduction via distroless Docker images and Linux Landlock sandboxing, Miri for detecting undefined behavior, graceful shutdown handling, circuit breakers, resource limits, and health check patterns for Kubernetes.
