Implementations

impl RecoveryStore

pub fn new(spec: RecoverySpec, state_dir: &Path) -> Self

pub fn path(&self) -> &Path

pub fn save( &self, snapshot: &str, broker: &PathBroker, ) -> Result<(), ShellError>

pub fn load(&self, broker: &PathBroker) -> Result<Option<String>, ShellError>

The saved snapshot, if any. Recovered file paths are re-granted (best effort: a file deleted since the crash simply is not granted).

pub fn migrate_legacy( &self, legacy: &Path, ) -> Result<MigrationOutcome, ShellError>

One-time migration of a snapshot an earlier version wrote to legacy.

The legacy file is validated (size and version) and copied atomically to the current path, then removed. Authority is not re-checked here: RecoveryStore::save and RecoveryStore::load still apply it. An invalid legacy file is an error and is left in place. If the current snapshot already exists, the legacy file is left alone.

pub fn clear(&self) -> Result<(), ShellError>
