To structure Rust web services, enforce async-by-default handlers and thread-safe shared state using Arc-based wrappers. This ensures safe concurrency and stateless handler execution during the API request lifecycles.

Domain constraints for API design in Rust codify design discipline for async HTTP servers. They enforce rules for middleware composition, input validation, observability, and standardized error handling to build robust web services.

To compose middleware and validation in axum, apply domain constraints that guide request lifecycle discipline via extractors. This standardizes how handlers process inputs and interact with shared state across web services.

These domain constraints apply to API development in Rust or similar ecosystems. While axum is a target, the underlying principles of async handlers and thread-safe state transfer to comparable async web frameworks.

The best way to manage request lifecycle and error handling in Rust APIs is enforcing standardized error handling and middleware composition. This design discipline ensures clear extraction and robust async server operations.
