Struct AmpConfigPersistenceService 

pub struct AmpConfigPersistenceService { /* private fields */ }

Application service coordinating amplifier configuration persistence.

Command handlers should depend on this service rather than on a repository directly. That keeps infrastructure details out of the command layer and provides one place to centralize snapshot-related behavior.

Implementations

impl AmpConfigPersistenceService

pub fn new(repository: Box<dyn AmpConfigPersistence>) -> Self

Creates the service with the chosen persistence backend.

pub fn load_amp_config(&self) -> Result<Option<AmpConfigDto>, String>

Loads the last persisted amplifier configuration, if any.

pub fn persist_from_audio_service( &self, audio_service: &AudioService, ) -> Result<(), String>

Captures a snapshot from the current AudioService state and enqueues it for persistence.

This is the primary method used by mutating Tauri commands after they successfully update amplifier state. Disk I/O is executed by a background worker thread so command handlers return quickly.

pub fn persist_snapshot(&self, snapshot: AmpConfigDto) -> Result<(), String>

Enqueues a precomputed snapshot for asynchronous persistence.
