Enumerations
enum class	cudf::lists::duplicate_find_option : int32_t { cudf::lists::FIND_FIRST = 0 , cudf::lists::FIND_LAST }
	Option to choose whether index_of() returns the first or last match of a search key in a list row. More...

Functions
std::unique_ptr< column >	cudf::lists::contains (cudf::lists_column_view const &lists, cudf::scalar const &search_key, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=cudf::get_current_device_resource_ref())
	Create a column of bool values indicating whether the specified scalar is an element of each row of a list column. More...
std::unique_ptr< column >	cudf::lists::contains (cudf::lists_column_view const &lists, cudf::column_view const &search_keys, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=cudf::get_current_device_resource_ref())
	Create a column of bool values indicating whether the list rows of the first column contain the corresponding values in the second column. More...
std::unique_ptr< column >	cudf::lists::contains_nulls (cudf::lists_column_view const &lists, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=cudf::get_current_device_resource_ref())
	Create a column of bool values indicating whether each row in the lists column contains at least one null element. More...
