Use the Tokio runtime with the axum framework for routing and handlers, sqlx or diesel for database access, and serde for serialization. Structure errors with thiserror and anyhow, and add tower middleware for authentication and logging.

Define custom error types with thiserror for libraries and use anyhow for application-level error propagation. Return Result types explicitly, convert errors with the From trait, and preserve context across module boundaries.

Lifetime errors usually signal unclear ownership; restructure so each value has one clear owner, use references for short-lived borrows, and apply Rc, Arc, or RefCell when shared or interior mutability is required. Explicit lifetime annotations resolve ambiguous cases in generics.

Yes, Rust supports lock-free programming through atomic operations in std::sync::atomic and crates like crossbeam. The ownership system enforces thread safety at compile time via the Send and Sync marker traits.

Avoid Rust for quick throwaway scripts, prototypes needing rapid iteration, or projects where a dynamic runtime is required. The compile-time safety guarantees add upfront design cost that does not pay off for short-lived tooling.
