Structure a Rust backend service using a 3-layer Clean Architecture: thin Presentation Commands, pure Domain Services for business logic, and Infrastructure Repositories for data access. This decoupled design enables clear boundaries, easy refactors, and scalable feature delivery.

Handle database migrations in a Rust Tauri application by using SQLite with SQLx migrations. This approach ensures robust data handling and secure schema updates while maintaining consistent infrastructure boundaries across your backend services.

The 3-layer Clean Architecture pattern works with Tauri by treating Commands as a thin Presentation wrapper. They delegate to Domain Services for pure business logic, which then interact with Infrastructure Repositories for database access.

Design DTOs in Rust backend services to drive your Commands, and use UUIDv4 for generating unique IDs. This DTO-driven approach ensures secure data handling and clear boundaries between your API presentation layer and internal domain logic.

Separating business logic from data access improves backend testing by creating clear boundaries between Domain Services and Infrastructure Repositories. This structural isolation enables straightforward unit and integration testing without needing to mock entire database systems.

You can apply this Rust backend architecture to features beyond EMMM2 because the 3-layer Clean Architecture pattern establishes generic, decoupled boundaries. The structural guidelines for Commands, Services, and Repositories support scalable feature delivery in any Rust application.
