Struct CagraIndex 

pub struct CagraIndex<'data, T: CagraElement> { /* private fields */ }

Query-local CAGRA index with a device-padded dataset. Rows already aligned to 16 bytes use a borrowed padded view; other rows use an owning padded copy. Native search requires a device-padded index (components/cuvs/cuvs/c/src/neighbors/cagra.cpp:1843).

Implementations

impl<'data, T: CagraElement> CagraIndex<'data, T>

pub fn build( resources: &CuvsResources, dataset: &ValidatedDeviceTensor<'data, T>, params: CagraIndexParams, ) -> Result<Self>

pub fn search_into( &self, queries: &ValidatedDeviceTensor<'_, T>, k: usize, params: CagraSearchParams, neighbors: &mut DeviceBuffer<i64>, distances: &mut DeviceBuffer<f32>, ) -> Result<KnnSearchOutput>

Search outputs are [queries.rows(), k]. Missing neighbors have ordinal i64::MAX.

pub fn rows(&self) -> usize

pub fn columns(&self) -> usize

pub fn close(self) -> Result<()>

Reports native destruction errors; failed destruction is retried on drop.

Trait Implementations

impl<T: CagraElement> Debug for CagraIndex<'_, T>

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

Formats the value using the given formatter.

impl<T: CagraElement> Drop for CagraIndex<'_, T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
