Struct BruteForceIndex 

pub struct BruteForceIndex<'data> { /* private fields */ }

A brute-force index that retains the dataset borrow and exact runtime binding.

Implementations

impl<'data> BruteForceIndex<'data>

pub fn build( resources: &CuvsResources, dataset: &ValidatedDeviceTensor<'data, f32>, metric: DistanceMetric, ) -> Result<Self>

Builds an index over dataset, a contiguous row-major or column-major matrix on the same exact runtime binding and CUDA device as resources.

The index borrows dataset for 'data and retains resources, so the dataset memory stays valid until the index is closed or dropped. A failed native build destroys the partial index before the error is returned.

pub fn search_into( &self, queries: &ValidatedDeviceTensor<'_, f32>, k: usize, neighbors: &mut DeviceBuffer<i64>, distances: &mut DeviceBuffer<f32>, ) -> Result<KnnSearchOutput>

Searches queries for their k nearest indexed rows and writes the results into neighbors and distances.

k must be nonzero and at most the indexed row count. queries must have the index’s column count and share its binding and device. Both output buffers must contain exactly n_queries * k elements, laid out as [n_queries, k] row-major. Success is returned only after the native outputs pass validation on the buffers’ execution binding: every neighbor index lies in 0..rows() and every distance is finite.

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 Debug for BruteForceIndex<'_>

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

Formats the value using the given formatter.

impl Drop for BruteForceIndex<'_>

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.
