Struct KeyValueDiskANNMappingMaintenance 

pub struct KeyValueDiskANNMappingMaintenance { /* private fields */ }

A finite retained discovery pass over index mappings followed by table mappings. Each step considers one mapping and removes at most that record and its preparation guard. Generation payloads and retained history are separate maintenance owners.

Implementations

impl KeyValueDiskANNMappingMaintenance

pub fn start( store: &Arc<dyn KeyValueStore>, control: &StorageReadControl, ) -> StorageBackendResult<Self>

pub fn step(&mut self) -> StorageBackendResult<Option<bool>>

Some(true) reclaimed a mapping (or observed a peer’s deletion); Some(false) retained one. None finishes the pass. An uncertain outcome preserves this same key until original completion is resolved.

pub fn commit_pending(&self) -> StorageBackendResult<()>

pub fn rollback_pending(&self) -> StorageBackendResult<()>

pub fn run( store: &Arc<dyn KeyValueStore>, control: &StorageReadControl, ) -> StorageBackendResult<()>
