Struct ConfigPersistence 

pub struct ConfigPersistence { /* private fields */ }

Configuration persistence manager

Provides atomic load/save operations with integrity verification and recovery support.

Implementations

impl ConfigPersistence

pub fn new(store: &GraphConfigStore) -> Self

Create a new persistence manager from a config store

pub fn from_paths(paths: GraphConfigPaths) -> Self

Create a new persistence manager from paths

pub fn load(&self) -> PersistenceResult<(GraphConfigFile, LoadReport)>

Load config with recovery support

Returns the loaded config and a report of any recovery actions taken.

Errors

Returns an error if no usable config file can be loaded or parsed.

pub fn exists(&self) -> bool

Check if config exists (either primary or previous)

pub fn save( &self, config: &mut GraphConfigFile, lock_timeout_ms: u64, tool: &str, ) -> PersistenceResult<()>

Save config atomically with locking

Arguments

• config - The config to save
• lock_timeout_ms - How long to wait for the lock
• tool - The tool performing the save (for lock info)

Errors

Returns an error if locking, serialization, or atomic write fails.

pub fn init( &self, lock_timeout_ms: u64, tool: &str, ) -> PersistenceResult<GraphConfigFile>

Initialize a new config file with defaults

Errors

Returns an error if the config cannot be saved.

pub fn quarantine_corrupt(&self, path: &Path) -> PersistenceResult<PathBuf>

Quarantine a corrupt config file

Errors

Returns an error if the corrupt file cannot be moved to quarantine.

pub fn repair(&self, lock_timeout_ms: u64) -> PersistenceResult<RepairReport>

Repair config by quarantining corrupt files and restoring from previous

Errors

Returns an error if lock acquisition or file operations fail.
