* Added new function compute_distance_to_codes_for_list to IndexIVF. Given a query vector x, this function computes distance to provided codes for the input list_no. This is a special purpose method to be used as a flat distance computer for an inverted list where codes are provided externally. This allows to use the quantizer independently while computing distance for the quantized codes. * This function is currently implemented only for IndexIVFScalarQuantizer. * Extended c_api interface for the new function.
