Class definition for cudf::column.
rmm::cuda_stream_view const get_default_stream()
Get the current default stream.
std::unique_ptr< column > apply_boolean_mask(lists_column_view const &input, lists_column_view const &boolean_mask, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=cudf::get_current_device_resource_ref())
Filters elements in each row of input LIST column using boolean_mask LIST of booleans as a mask.
std::unique_ptr< column > distinct(lists_column_view const &input, null_equality nulls_equal=null_equality::EQUAL, nan_equality nans_equal=nan_equality::ALL_EQUAL, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=cudf::get_current_device_resource_ref())
Create a new list column without duplicate elements in each list.
rmm::device_async_resource_ref get_current_device_resource_ref()
Get the current device memory resource reference.
