You decide if a Rust domain concept is an Entity or Value Object by clarifying identity versus value semantics. Entities maintain a distinct identity, whereas Value Objects are defined solely by their attribute values and are immutable.

To define aggregation boundaries and ownership semantics in Rust, you apply domain-driven design decision prompts. This enforces aggregation boundaries and dictates the appropriate ownership model for your domain concepts.

The best way to map domain-driven design patterns to Rust is to classify your domain concept first. You then enforce identity rules and select the appropriate Rust pattern, such as Aggregate Root or Repository, to define invariants.

Yes, you can use this approach for codebase architecture reviews in Rust. It evaluates existing domain concepts by enforcing identity rules, ownership semantics, and aggregation boundaries during the architecture review session.

You should model a domain concept as an Aggregate Root in Rust when it serves as a consistency boundary for a cluster of domain objects. This pattern enforces invariants and manages ownership semantics within its specific aggregation boundaries.
