3//! Generated by metaphor-schema. Do not edit manually.
4//!
5//! Type alias over `GenericCrudService` — all CRUD logic lives in backbone-core.
6//! For custom behaviour, create `attribute_service_custom.rs` (preserved on regen).

16/// All 12 standard CRUD operations (list, create, get, update, patch,
17/// soft_delete, restore, empty_trash, bulk_create, upsert, find_by_id,
18/// list_deleted) are provided by `GenericCrudService`.
19///
20/// Custom extensions go in `attribute_service_custom.rs`:
21///
22/// ```rust,ignore
23/// pub struct AttributeServiceCustom {

25///     // add domain-specific dependencies here
26/// }
