//! Settings and app-config use-case implementation.
|
||
|
|
//!
|
||
|
|
//! `SettingsServiceImpl` implements [`SettingsService`] from the domain
|
||
|
|
//! layer. It is generic over `S: SettingsRepository` and `C: AppConfigRepository`,
|
||
|
|
//! delegating persistence to those adapters.
|
||
|
|
//!
|
||
|
|
//! # Flow
|
||
|
|
//!
|
||
|
|
//! Each method delegates to the appropriate injected repository with the
|
||
|
|
//! configured `base_dir`. The `update_provider` method coordinates between
|
||
|
|
//! both repositories: load app config → mutate provider map → save app config.
