Rust for The Curious C++ Developers
summary
Claims that Rust enforces correctness beyond memory safety, pushing many bugs from runtime to compile time, and that real projects see fewer memory and concurrency vulnerabilities. Concrete features covered: Option and Result enums with pattern matching and the ? operator, move by default semantics, Send/Sync traits that forbid data races, and composable iterators. Tooling: cargo + crates, docs-as-tests, Miri and sanitizers for unsafe/FFI, plus interoperability pain with bindgen, cxx and emerging Google-backed kubit. Adoption costs exist but companies report measurable improvement.
