Struct SearchParams

pub struct SearchParams(pub cuvsIvfPqSearchParams_t);

Supplemental parameters to search IvfPq index

Tuple Fields

0: cuvsIvfPqSearchParams_t

Implementations

impl SearchParams

pub fn new() -> Result<SearchParams>

Returns a new SearchParams object

pub fn set_n_probes(self, n_probes: u32) -> SearchParams

The number of clusters to search.

pub fn set_lut_dtype(self, lut_dtype: cudaDataType_t) -> SearchParams

Data type of look up table to be created dynamically at search time. The use of low-precision types reduces the amount of shared memory required at search time, so fast shared memory kernels can be used even for datasets with large dimansionality. Note that the recall is slightly degraded when low-precision type is selected.

pub fn set_internal_distance_dtype( self, internal_distance_dtype: cudaDataType_t, ) -> SearchParams

Storage data type for distance/similarity computation.

Trait Implementations

impl Debug for SearchParams

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

Formats the value using the given formatter.

impl Drop for SearchParams

fn drop(&mut self)

Executes the destructor for this type.
