Struct SelectedVectorRead 

pub struct SelectedVectorRead { /* private fields */ }

Implementations

impl SelectedVectorRead

pub fn capture( base: Option<VectorReadSnapshot>, dimensions: u32, selected: impl IntoIterator<Item = (DocId, Option<VectorReadSnapshot>)>, control: &StorageReadControl, ) -> StorageBackendResult<VectorReadSnapshot>

Retain already evaluated replacements/deletions in strictly increasing document order. None for the base means the supplied selection is the entire visible field. Capture inspects only controls and dimensions.

Trait Implementations

impl VectorRead for SelectedVectorRead

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

Trustworthy identity of this complete fixed field, obtained from retained metadata. None means fixed-model reuse cannot be verified; callers must not replace it with a user-supplied label.

fn check_control( &self, control: &StorageReadControl, ) -> StorageBackendResult<()>

fn dimensions(&self) -> u32

fn next_document_after( &self, after: Option<DocId>, control: &StorageReadControl, ) -> StorageBackendResult<Option<DocId>>

fn document_vector_count( &self, document: DocId, control: &StorageReadControl, ) -> StorageBackendResult<u64>

Validate contiguous ordinal keys and return their count. Missing and explicitly empty tensors both have zero vectors.

fn read_vector( &self, document: DocId, ordinal: u32, control: &StorageReadControl, ) -> StorageBackendResult<Option<BudgetedVec<f32>>>

Read one ordinal without invoking a caller while a provider read lock is held. Absent ordinals return None; malformed values fail.
