//! Bank repository implementation for data persistence operations.
|
|
//!
|
|
//! This module provides the data access layer for bank account management,
|
|
//! implementing the repository pattern to abstract database operations.
|
|
//!
|
|
//! For full documentation and examples, see the [crate README](../README.md).
