Implementations

impl BuildQuantizer

pub fn train<Data, StorageProvider>( build_quantization_type: &QuantizationType, index_path_prefix: &str, index_configuration: &IndexConfiguration, pq_storage: &PQStorage, storage_provider: &StorageProvider, ) -> ANNResult<Self>

where Data: GraphDataType<VectorIdType = u32>, StorageProvider: StorageReadProvider + StorageWriteProvider,

Train a new quantizer from scratch.

pub fn load<StorageProvider>( build_quantization_type: &QuantizationType, index_path_prefix: &str, storage_provider: &StorageProvider, ) -> ANNResult<Self>

where StorageProvider: StorageReadProvider,

Load a previously trained quantizer from storage.
