Functions
std::unique_ptr< cudf::column >	cudf::unary_operation (cudf::column_view const &input, cudf::unary_operator op, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
	Performs unary op on all values in column. More...
std::unique_ptr< cudf::column >	cudf::is_null (cudf::column_view const &input, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
	Creates a column of type_id::BOOL8 elements where for every element in input true indicates the value is null and false indicates the value is valid. More...
std::unique_ptr< cudf::column >	cudf::is_valid (cudf::column_view const &input, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
	Creates a column of type_id::BOOL8 elements where for every element in input true indicates the value is valid and false indicates the value is null. More...
std::unique_ptr< column >	cudf::cast (column_view const &input, data_type out_type, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
	Casts data from dtype specified in input to dtype specified in output. More...
std::unique_ptr< column >	cudf::is_nan (cudf::column_view const &input, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
	Creates a column of type_id::BOOL8 elements indicating the presence of NaN values in a column of floating point values. The output element at row i is true if the element in input at row i is NAN, else false More...
std::unique_ptr< column >	cudf::is_not_nan (cudf::column_view const &input, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::mr::device_memory_resource *mr=rmm::mr::get_current_device_resource())
	Creates a column of type_id::BOOL8 elements indicating the absence of NaN values in a column of floating point values. The output element at row i is false if the element in input at row i is NAN, else true More...
