Implementations

impl MetaCacheEntries

pub fn as_ref(&self) -> &[Option<MetaCacheEntry>]

pub fn resolve( &self, params: MetadataResolutionParams, ) -> Option<MetaCacheEntry>

pub fn resolve_with_write_quorum( &self, params: MetadataResolutionParams, ) -> Option<MetaCacheEntry>

pub fn resolve_union(&self, bucket: &str) -> Option<MetaCacheEntry>

Resolve the cross-disk UNION of every version present on ANY disk slot.

This mirrors MinIO’s global heal enumeration (cmd/global-heal.go healErasureSet -> listPathRaw with objQuorum = 1 feeding mergeEntries/mergeXLV2Versions): at quorum 1 the merge is forced strict and returns the union of all per-disk version streams, so a version that survives on FEWER than read-quorum disks is still surfaced for healing. Read-quorum resolution (resolve with obj_quorum >= 2) would silently drop such a sub-quorum version, which is exactly the durability gap this enumerator closes (backlog#920).

bucket is only used to tag the merged entry; strict:false lets the non-strict header reconciliation collapse equal-but-differently-signed replicas of the SAME version id while still retaining genuinely distinct version ids.

pub fn discover_heal_candidates( &self, bucket: &str, max_candidates: usize, ) -> MetaCacheHealDiscovery

Discover validated object/delete-marker versions and safe unversioned inspection candidates in the raw entries without applying read quorum. This is intentionally separate from Self::resolve: a sub-quorum version is a valid heal target even though it must not participate in normal reads or writes.

The validated list is bounded and deduplicated by object, version id, and metadata kind; each candidate retains the number of raw disk entries that carried it so callers can classify sub-quorum versions. Entries whose xl.meta cannot be decoded are counted separately for discovery accounting; they never become versionless destructive heal requests and do not consume the validated quota. An MetaCacheHealCandidateKind::UnversionedObject is always consumed by a non-destructive scanner request.
