rmm::cuda_stream_view const get_default_stream()
Get the current default stream.
std::unique_ptr< column > to_lower(strings_column_view const &strings, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=rmm::mr::get_current_device_resource())
Converts a column of strings to lower case.
std::unique_ptr< column > to_upper(strings_column_view const &strings, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=rmm::mr::get_current_device_resource())
Converts a column of strings to upper case.
std::unique_ptr< column > swapcase(strings_column_view const &strings, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=rmm::mr::get_current_device_resource())
