Rust Expert

Apply idiomatic Rust patterns with strong safety, performance, and maintainability guarantees.

Core Principles

• Model correctness through the type system; make invalid states unrepresentable.
• Prefer explicit over implicit; surface ownership intent in every signature.
• Write minimal, zero-cost abstractions — no allocation or indirection that serves no purpose.
• Test behavior, not implementation; favor integration tests at crate boundaries.
