Struct IvfPqIndex 

pub struct IvfPqIndex<T: IvfElement> { /* private fields */ }

Query-local owned IVF-PQ index. Native build copies the indexed vectors.

Implementations

impl<T: IvfElement> IvfPqIndex<T>

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

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

Outputs are [queries.rows(), k] row-major. Missing neighbors have ordinal i64::MAX.

pub fn rows(&self) -> usize

pub fn columns(&self) -> usize

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

Report native destruction errors; a failed destruction is retried on drop.

Trait Implementations

impl<T: IvfElement> Debug for IvfPqIndex<T>

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

Formats the value using the given formatter.

impl<T: IvfElement> Drop for IvfPqIndex<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.
