Thread-safe shared handle to the FrecencyTracker instance.

Implementations

impl SharedFrecency

pub fn noop() -> Self

Creates a disabled instance that silently ignores all writes.

pub fn read( &self, ) -> Result<RwLockReadGuard<'_, Option<FrecencyTracker>>, Error>

pub fn write( &self, ) -> Result<RwLockWriteGuard<'_, Option<FrecencyTracker>>, Error>

pub fn init(&self, tracker: FrecencyTracker) -> Result<(), Error>

Initialize the frecency tracker. No-op if this is a disabled instance.

pub fn spawn_gc( &self, db_path: String, use_unsafe_no_lock: bool, ) -> Result<JoinHandle<()>>

Spawn a background GC thread for this frecency tracker.

pub fn destroy(&self) -> Result<Option<PathBuf>, Error>

Drop the in-memory tracker and delete the on-disk database directory.

Acquires the write lock, ensuring all readers (including any active mmap access) are finished before the LMDB environment is closed and the files are removed.

Returns Ok(Some(path)) with the deleted path, or Ok(None) if no tracker was initialized.
