Manager for tombstone-based logical deletion

Provides O(1) deletion checks during vector retrieval.

Implementations

impl TombstoneManager

pub fn new(path: impl AsRef<Path>, writable: bool) -> Result<Self>

Create a new tombstone manager

If the file exists, loads existing tombstones. If not, creates a new empty tombstone file.

pub fn delete(&self, id: InternalId) -> Result<bool>

Mark an ID as deleted

pub fn delete_batch(&self, ids: &[InternalId]) -> Result<usize>

Mark multiple IDs as deleted

pub fn is_deleted(&self, id: InternalId) -> bool

Check if an ID is deleted

pub fn filter_deleted(&self, ids: &[InternalId]) -> Vec<InternalId>

Check multiple IDs for deletion

pub fn count(&self) -> u64

Get the count of deleted IDs

pub fn all_deleted(&self) -> Vec<InternalId>

Get all deleted IDs (for compaction)

pub fn sync(&self) -> Result<()>

Sync to disk

pub fn compact(&self) -> Result<()>

Compact the tombstone file (rewrites without duplicates)
