Struct VectorFieldGuardMaintenance 

pub struct VectorFieldGuardMaintenance { /* private fields */ }

A finite key-only discovery pass. Each step revisits one current field and conditionally deletes its reference marker. Retained readers keep the old records; ordinary document writers retain their lifetime observation and mergeable markers. Uncertain commits keep the current key and original attempt until explicit completion.

Implementations

impl VectorFieldGuardMaintenance

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

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

None completes discovery. Some(true) deletes the current empty field’s live marker; Some(false) leaves a live field, a tombstone, or a racing writer for later maintenance.

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

Resolve the retained original commit; the next step advances the cursor without reevaluating the completed field.

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

pub fn run( store: &VersionedKeyValueStore, control: &StorageReadControl, ) -> StorageBackendResult<()>
