Rust and Other Interesting Things
summary
Recent experience shows Rust can beat hand‑optimized C on real system code by switching data structures and letting the compiler optimize memory layout, notably a B‑tree implementation outperforming an AVL tree in a rebalancing workload. Rust’s ownership model shifts correctness checks to compile time, adding safety and composability while preserving performance. Practical tools include FFI and unsafe blocks for incremental migration, hygienic macros for ergonomics, and a thriving ecosystem that makes rewriting firmware and user‑level system services realistic.
