backbone-banking 0.11.0

//! Application service for BankTransaction entities
//!
//! Generated by metaphor-schema. Do not edit manually.
//!
//! Type alias over `GenericCrudService` — all CRUD logic lives in backbone-core.
//! For custom behaviour, create `bank_transaction_service_custom.rs` (preserved on regen).
