LogicalVectorIndex

lance::index::vector

Struct LogicalVectorIndex 

Source 
pub struct LogicalVectorIndex { /* private fields */ }
Expand description

A materialized snapshot of one logical vector index and all of its segments.

Implementations§

Source§

impl LogicalVectorIndex

Source

pub fn name(&self) -> &str

Returns the logical index name.

Source

pub fn column(&self) -> &str

Returns the vector column that this logical index is built on.

Source

pub fn num_segments(&self) -> usize

Returns the number of physical segments in this logical index.

Source

pub fn metadatas(&self) -> impl ExactSizeIterator<Item = &IndexMetadata> + '_

Returns the committed metadata for all physical segments.

Source

pub fn num_rows_per_segment(&self) -> Vec<(Uuid, u64)>

Returns the indexed row count for each segment.

Source

pub fn as_ivf(&self) -> Result<LogicalIvfView<'_>>

Returns an IVF view over this logical index.

This is currently fallible only to leave room for future non-IVF vector index families. All vector indices currently opened through this path are IVF-backed.
