Use the Tokio runtime with the axum framework for routing and handlers. Add tower middleware for concerns like authentication, sqlx or diesel for database access, and serde for serialization.

Use thiserror to define custom error types in libraries and anyhow for application-level error propagation. Combine them with Result combinators and structured logging for clear error context.

Analyze ownership and borrowing rules to identify conflicting references, then restructure using explicit lifetime annotations, smart pointers like Arc or RefCell, or the newtype pattern. The skill covers lifetime elision rules and common fixes.

Yes, Rust supports FFI with C libraries using extern blocks and raw pointers, with bindgen generating bindings automatically. Unsafe blocks must document safety invariants and be wrapped in safe abstractions.

Avoid Rust when you need a quick throwaway script, a dynamic runtime, or cannot introduce Rust into the existing stack. It is best suited for performance-critical, memory-safe systems and services.
