Enum MetadataTableFamily 

pub enum MetadataTableFamily {
    Inodes,
    DirentryBinds,
    DirentryChildBinds,
    DirentryUnbinds,
    Revisions,
    RevisionsByInodeDesc,
    Tombstones,
    ActiveDeletions,
    CommitReceipts,
    Attributes,
}

Selects a metadata row family and its durable lookup ordering.

See metadata segments.

Variants

Inodes

Stores inode identity, kind, and creation position.

DirentryBinds

Orders directory bindings for parent-and-name visibility lookups.

DirentryChildBinds

Re-indexes directory bindings by child for parent discovery.

DirentryUnbinds

Stores immutable events that retire exact historical bindings.

Revisions

Stores file revisions in their canonical durable ordering.

RevisionsByInodeDesc

Re-indexes file revisions for newest-first per-inode reads.

Tombstones

Stores set and revoke events used to determine active subtree tombstones.

ActiveDeletions

Names the deletions that are recoverable right now, derived from the tombstone family and ordered by deletion time.

CommitReceipts

Preserves commit idempotency evidence independently of retained WAL history.

Attributes

Stores inode attribute revisions newest-first.

Attributes are read only in this order, so the family has no secondary index and requires no cross-family parity check.

Implementations

impl MetadataTableFamily

pub const fn row_key_prefix(self) -> &'static str

The fixed text every row key in this family starts with, up to but not including the family’s first variable component.

Defined here because it is the front of MetadataRow::row_key_for_family and must change with it; row_key_prefixes_match_the_row_keys_they_front holds the two together. A streaming compaction reads its retention groupings out of the components that follow this prefix, so the boundary between two groupings is this prefix followed by whole component values (format spec, “Compaction”).
