We have
extract_transform_(if_)v_frontier_outgoing_ewhich works on a source major graph (store_transposed = false).Similarly, we have
per_v_pair_dst_nbr_intersection,per_v_pair_transform_dst_nbr_intersection, andtransform_reduce_dst_nbr_intersection_of_e_endpoints_by_v(store_transposed = false).This PR add
extract_transform_(if_)v_frontier_outgoing_ewhich work on a destination major graph (store_transposed = true) andper_v_pair_src_nbr_intersection,per_v_pair_transform_src_nbr_intersection,transform_reduce_src_nbr_intersection_of_e_endpoints_by_v(store_transposed = true).This is breaking because
detail::edge_op_result_typeis updated (include/cugraph/prims/property_op_utils.cuh) and primitive files are renamed (extract_transform_(if_)v_frontier_outgoing_e.cuh=>extract_transform_(if_)v_frontier_incoming_outgoing_e.cuh,per_v_pair_dst_nbr_intersection.cuh=>per_v_pair_src_dst_nbr_intersection.cuh, and so on).This functor (
detail::edge_op_result_type) is updated so we can deduce the return value of an edge operator regardless whether the source is tagged (store_transposed = false) or the destination is tagged (store_transposed = true).
