Struct MetadataIndex 

pub struct MetadataIndex { /* private fields */ }

Key-addressed metadata used to filter owned or memory-mapped indexes.

Implementations

impl MetadataIndex

pub const fn new() -> Self

pub fn insert(&mut self, key: u64, metadata: Metadata) -> Option<Metadata>

pub fn remove(&mut self, key: u64) -> Option<Metadata>

pub fn get(&self, key: u64) -> Option<&Metadata>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl ExactSizeIterator<Item = (u64, &Metadata)>

pub fn matches(&self, key: u64, filter: &MetadataFilter) -> bool

pub fn matching_keys(&self, filter: &MetadataFilter) -> BTreeSet<u64>

impl MetadataIndex

pub fn search( &self, index: &VectorIndex, query: &[f32], count: usize, filter: &MetadataFilter, ) -> Result<Vec<SearchHit>, SearchError>

Searches an owned index and guarantees enough filtered hits through the index’s exact fallback.

Errors

Returns a typed query or allocation error.

pub fn search_mapped( &self, index: &MappedVectorIndex, query: &[f32], count: usize, filter: &MetadataFilter, ) -> Result<Vec<SearchHit>, SearchError>

Searches a memory-mapped index with the same filter semantics.

Errors

Returns a typed query or allocation error.

Performs copy-assignment from source.

impl Debug for MetadataIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for MetadataIndex

fn default() -> MetadataIndex

Returns the “default value” for a type.
