A set of cudf::column_view's of the same size.
Definition: table_view.hpp:200
Class definition for cudf::column.
std::unique_ptr< table > tile(table_view const &input, size_type count, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=cudf::get_current_device_resource_ref())
Repeats the rows from input table count times to form a new table.
flip_endianness
Configures whether byte casting flips endianness.

std::unique_ptr< column > interleave_columns(table_view const &input, rmm::cuda_stream_view stream=cudf::get_default_stream(), rmm::device_async_resource_ref mr=cudf::get_current_device_resource_ref())
Interleave columns of a table into a single column.
