Implementations

impl MetadataState

pub fn apply_committed_wal_deltas( &self, committed_seq: ChangeSeq, committed_at_ms: u64, deltas: &[WalDelta], ) -> MetadataState

pub fn apply_committed_wal_deltas_mut( &mut self, committed_seq: ChangeSeq, committed_at_ms: u64, deltas: &[WalDelta], )

pub fn active_subtree_tombstone( &self, root_inode_id: InodeId, base_seq: ChangeSeq, ) -> Option<SubtreeTombstoneRecord>

pub fn covering_subtree_tombstone( &self, inode_id: InodeId, base_seq: ChangeSeq, ) -> Option<SubtreeTombstoneRecord>

pub fn visible_inode( &self, inode_id: InodeId, base_seq: ChangeSeq, ) -> Option<InodeRecord>

pub fn visible_child( &self, parent_inode_id: InodeId, name_key: &NameKey, base_seq: ChangeSeq, ) -> Option<DirentryBindRecord>

pub fn resolve_visible_path( &self, absolute_path: &AbsolutePath, base_seq: ChangeSeq, ) -> Result<ResolvedVisiblePath, VisiblePathError>

pub fn would_create_directory_cycle( &self, inode_id: InodeId, new_parent_inode_id: InodeId, base_seq: ChangeSeq, ) -> bool

impl MetadataState

pub fn indexed_seq(&self) -> ChangeSeq

Highest sequence carried by any indexed record.

No record carries a larger seq, so a query at base_seq >= indexed_seq() passes every seq <= base_seq filter and is equivalent to an at-head query. The seq-gated read methods below rely on this to route to the indexes; only queries strictly below indexed_seq() need the historical scans.

pub fn inodes(&self) -> &[InodeRecord]

pub fn direntry_binds(&self) -> &[DirentryBindRecord]

pub fn direntry_unbinds(&self) -> &[DirentryUnbindRecord]

pub fn revisions(&self) -> &[RevisionRecord]

pub fn subtree_tombstones(&self) -> &[SubtreeTombstoneRecord]

pub fn commit_receipts(&self) -> &[CommitReceiptRecord]

pub fn row_count(&self) -> usize

pub fn decoded_bytes(&self) -> usize

pub fn find_commit_receipt( &self, commit_id: &CommitId, ) -> Option<&CommitReceiptRecord>
