Domain-driven design patterns for modeling entities, value objects, and aggregates in Rust. \n \n Distinguishes between Entities (unique identity required), Value Objects (interchangeable by value), and Aggregates (owned hierarchies), with clear Rust patterns for each \n Emphasizes invariant preservation through private fields, validated constructors, and type-state patterns \n Provides templates for common DDD structures: newtypes for value objects, structs with ID fields for entities, and modu
