Concepts
concept	uni20::linalg::reduction_detail::HostOutput
	Reduction output that is either a host scalar or host-writable mdspec.

Typedefs
template<class Output >
using	uni20::linalg::reduction_detail::host_output_t = typename HostOutputType< Output >::type
	Resolved output type used by a host reduction backend probe.

Functions

consteval bool	uni20::linalg::reduction_detail::output_is_supported ()
	Report whether an output can receive a reduction value of fixed rank.
template<class Output , class Function >
KernelAttempt	uni20::linalg::reduction_detail::with_host_output (Output &output, Function &&function)
	Invoke a synchronous reduction with a resolved host output.
template<class Output , class Scalar >
void	uni20::linalg::reduction_detail::write_host_output (Output &output, Scalar value)
	Store a scalar in either a resolved rank-zero mdspan or C++ scalar.
