Thread-safe shared handle to the QueryTracker instance.

Implementations

impl SharedQueryTracker

pub fn noop() -> Self

Creates a disabled instance that silently ignores all writes.

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

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

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

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

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.
