apply_sorting_struct_binary_op()

void cudf::binops::compiled::detail::apply_sorting_struct_binary_op	(	mutable_column_view &	out,
		column_view const &	lhs,
		column_view const &	rhs,
		bool	is_lhs_scalar,
		bool	is_rhs_scalar,
		binary_operator	op,
		rmm::cuda_stream_view	stream
	)

struct binary operation using NaN aware sorting physical element comparators

Parameters

out	mutable view of output column
lhs	view of left operand column
rhs	view of right operand column
is_lhs_scalar	true if lhs is a single element column representing a scalar
is_rhs_scalar	true if rhs is a single element column representing a scalar
op	binary operator identifier
stream	CUDA stream used for device memory operations

scalar_col_valid_mask_and()

std::pair<rmm::device_buffer, size_type> cudf::binops::scalar_col_valid_mask_and	(	column_view const &	col,
		scalar const &	s,
		rmm::cuda_stream_view	stream = cudf::get_default_stream(),
		rmm::mr::device_memory_resource *	mr = rmm::mr::get_current_device_resource()
	)

Computes output valid mask for op between a column and a scalar.

Parameters

col	Column to compute the valid mask from
s	Scalar to compute the valid mask from
stream	CUDA stream used for device memory operations and kernel launches
mr	Device memory resource used to allocate the returned valid mask

Returns

Computed validity mask
