Class definition for cudf::column.
std::unique_ptr< column > count_characters(strings_column_view const &input, rmm::device_async_resource_ref mr=rmm::mr::get_current_device_resource())
Returns a column containing character lengths of each string in the given column.
std::unique_ptr< column > code_points(strings_column_view const &input, rmm::device_async_resource_ref mr=rmm::mr::get_current_device_resource())
Creates a numeric column with code point values (integers) for each character of each string.
std::unique_ptr< column > count_bytes(strings_column_view const &input, rmm::device_async_resource_ref mr=rmm::mr::get_current_device_resource())
Returns a column containing byte lengths of each string in the given column.
