Does this skill help with input validation?

Yes, it promotes the 'Always Valid' pattern where constructors validate data before returning a Newtype, ensuring business rules are satisfied before the object can be used.

What is the difference between an Entity and a Value Object in this skill?

Entities are defined by a unique identity (like a User ID) where the identity persists across changes. Value Objects are defined by their attributes (like an Email address) and are treated as interchangeable and immutable.

How does this skill handle Rust's ownership model?

It aligns DDD concepts with Rust ownership: Aggregate Roots own their children to ensure consistency, while Value Objects typically implement Clone or Copy for easy sharing.

What is the Repository pattern in this context?

It provides a trait-based abstraction for persistence, allowing your domain logic to remain independent of whether you are using SQL, NoSQL, or in-memory storage.

API Development

Guides the implementation of Domain-Driven Design (DDD) patterns in Rust to create robust, invariant-safe business logic.

This skill empowers Claude to architect complex Rust applications using Domain-Driven Design principles. It bridges the gap between high-level business requirements and low-level Rust implementation by providing structured patterns for entities, value objects, aggregates, and repositories. By focusing on domain invariants, ownership rules, and type-driven safety, it ensures that your domain model is not only expressive but also leverages Rust's compiler to prevent illegal states and logical errors.

Key Features

01Enforces domain invariants through private fields and validated constructors

02Provides templates for Repository traits and Domain Event enums

03Maps DDD concepts like Entities and Value Objects to idiomatic Rust patterns

04Guides aggregate boundary design using Rust's ownership and module system

06Facilitates type-driven development to eliminate primitive obsession

Use Cases

01Designing type-safe APIs that validate business rules at the boundary

02Architecting complex business logic for fintech, e-commerce, or enterprise systems

03Refactoring legacy Rust codebases into clean, decoupled domain layers
