Before writing ANY new code:
src/core/services/, src/core/traits/src/core/| Layer | Location | Max Lines |
|---|---|---|
| Handlers | src/modules/[feature]/handlers.rs | 50 |
| Services | src/modules/[feature]/services.rs | 100 |
| Repositories | src/modules/[feature]/repository.rs | 100 |
| Traits | src/modules/[feature]/traits.rs | 30 |
| Models | src/modules/[feature]/models.rs | 50 |
| Shared | src/core/{services,traits,models}/ | - |
NEVER use flat src/ structure - always src/modules/[feature]/
| Rule | Value |
|---|---|
| File limit | 100 lines (split at 90) |
| Handlers | < 50 lines, delegate to services |
| Traits | traits.rs or src/core/traits/ ONLY |
| Rustdoc | /// on every public item |
| Error handling | Use thiserror for custom errors |
| Generics | Use trait bounds, not concrete types |
| Topic | Reference | When to consult |

| SRP | single-responsibility.md | Fat structs |
| OCP | open-closed.md | Adding impls |
| LSP | liskov-substitution.md | Trait contracts |
| ISP | interface-segregation.md | Fat traits |
| DIP | dependency-inversion.md | Generics/DI |

| Template | When to use |
|---|---|
| module.md | Feature module structure |
| service.md | Business logic service |
| trait-def.md | Trait definition |
| handler.md | HTTP handler (Axum) |
| error.md | Custom errors (thiserror) |
| test.md | Unit + integration tests |
| Anti-Pattern | Fix |
|---|---|
| Files > 100 lines | Split at 90 |
| Traits in impl files | Move to traits.rs |
Box<dyn Any> | Use proper trait bounds |
Flat src/ structure | Use src/modules/[feature]/ |
| Unwrap in library code | Use Result<T, E> |
