Typedefs
template<typename T , std::size_t Extent = cuda::std::dynamic_extent>
using	cudf::device_span = cuda::std::span< T, Extent >
	Device span is an alias of cuda::std::span.
template<class T >
using	cudf::detail::host_2dspan = base_2dspan< T, host_span >
	Alias for the 2D span for host data. More...

Typedef Documentation

device_2dspan

template<class T >

using cudf::detail::device_2dspan = typedef base_2dspan<T, device_span>

Alias for the 2D span for device data.

Index operator returns rows as device_span.

Definition at line 439 of file span.hpp.

host_2dspan

template<class T >

using cudf::detail::host_2dspan = typedef base_2dspan<T, host_span>

Alias for the 2D span for host data.

Index operator returns rows as host_span.

Definition at line 431 of file span.hpp.
