Trait AmpConfigPersistence 

Source 
pub trait AmpConfigPersistence: Send + Sync {

    fn save(&self, config: &AmpConfigDto) -> Result<(), String>;
}
Expand description

Backend abstraction for amplifier configuration persistence.

This trait isolates the rest of the application from the concrete storage mechanism.

Implementations are expected to:

  • return Ok(None) when no persisted config exists yet,
  • return Err(String) when the data exists but cannot be read or parsed,
  • persist a full amplifier snapshot on save.

Required Methods§

Source

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

Loads the most recently persisted amplifier configuration.

Returns Ok(None) when no stored configuration is available yet.

Source

fn save(&self, config: &AmpConfigDto) -> Result<(), String>

Persists the supplied amplifier configuration snapshot.

Implementations should overwrite the previous snapshot atomically from the application’s point of view: after a successful return, the new state is considered the canonical persisted config.
