Can I use this for complex business rule validation?

Yes, the skill emphasizes using private fields with validated constructors (Newtypes) and the type-state pattern to ensure objects are always in a valid state.

Does it support the Repository pattern?

The skill provides trait-based patterns for Repositories, allowing you to abstract persistence logic away from your core domain entities.

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

Entities are modeled as structs with unique IDs where identity matters, while Value Objects are modeled as shareable, immutable structs that are interchangeable by value.

How does this skill handle Rust's ownership for aggregates?

It maps Aggregate Roots to structs that own their children, ensuring a clear ownership tree that aligns with Rust's borrow checker and memory safety rules.

API Development

Guides the implementation of Domain-Driven Design patterns in Rust to ensure type-safe business logic and strict data invariants.

About

The m09-domain skill assists developers in architecting complex Rust applications using Domain-Driven Design (DDD) principles. It provides structured patterns for distinguishing between Entities and Value Objects, defining aggregate boundaries, and implementing repositories while leveraging Rust's unique ownership and type systems. By focusing on Layer 2 design choices, it helps translate abstract business rules into concrete Rust implementations like the type-state pattern and newtype wrappers, ensuring that domain invariants are enforced at compile-time rather than runtime.

Key Features

Maps DDD concepts like Entities and Value Objects to specific Rust patterns and traits
Provides templates for Repository traits and Domain Event enums
0 GitHub stars
Defines clear Aggregate boundaries using Rust's ownership and module systems
Utilizes the Type-State pattern to handle complex domain transitions safely
Enforces business invariants through private fields and validated constructors

Use Cases

Refactoring legacy codebases to eliminate primitive obsession using type-safe newtypes
Designing robust financial or e-commerce domain models with strict validation requirements
Establishing clear ownership trees and consistency boundaries in large-scale Rust projects
