Fields

manifest: DiskANNManifest

corpus_fingerprint: Option<[u8; 32]>

None is an unverifiable canonical selection, never permission to trust a caller’s version label.

canonical_counts: Option<DiskANNCanonicalCounts>

Exact selected-view populations when maintained by the canonical owner; absence is not a measured zero.

read_limits: DiskANNReadLimits

read_capabilities: DiskANNReadCapabilities

Implementations

impl DiskANNQueryMetadata

pub fn query_statistics( &self, query: &[f32], control: &StorageReadControl, ) -> StorageBackendResult<DiskANNQueryStats>

Project stored physical facts and classify the query with the same canonical norm calculation as execution, without normalizing coordinates or reading artifact bodies.

pub fn index_statistics( &self, control: &StorageReadControl, ) -> StorageBackendResult<DiskANNIndexStats>

Project the selected field without evaluating query arguments or preparing search artifacts.

impl DiskANNQueryMetadata

pub fn capture( canonical: &dyn DiskANNCanonicalRead, source: &dyn DiskANNPageSource, parameters: DiskANNIndexParams, limits: DiskANNReadLimits, control: &StorageReadControl, ) -> StorageBackendResult<Self>

Read the bounded manifest, canonical identity and maintained counts from an already associated provider view. This validates the selected definition, not graph/PQ/origin bodies; opening an executable reader retains its complete validation. No vector query or logical observation is performed.

pub fn index_fingerprint( &self, control: &StorageReadControl, ) -> StorageBackendResult<[u8; 32]>

Versioned SHA-256 of the complete validated manifest, including physical incarnations, graph/PQ generation, build revisions and effective candidate-selection settings.
