basic_sender_t

template<typename... Args>

using Tests::Utils::basic_sender_t = typename stdexec::__basic_sender<Args...>::type

See https://github.com/NVIDIA/stdexec/pull/1873#discussion_r2834863237.

Definition at line 10 of file stdexec.hpp.

Function Documentation

are_same_instances()

template<Kokkos::ExecutionSpace Exec, Kokkos::ExecutionSpace OtherExec>

bool Tests::Utils::are_same_instances	(	const Exec &	exec,
		const OtherExec &	other_exec )

Definition at line 13 of file kokkos.hpp.

atomic_add()

template<typename T>

void Tests::Utils::atomic_add	(	T *	ptr,
		const T	val )

Atomically add val to *ptr using system scope and relaxed memory order.

Definition at line 34 of file atomic.hpp.

check_continues_on()

template<stdexec::scheduler Schd>

bool Tests::Utils::check_continues_on ( )

consteval

Check how the scheduler customizes stdexec::continues_on.

Use this function to ensure your own scheduler is properly customizing everything that's needed.

Check the complete "demangled" sender type.

Diagnose any issue that could make the resulting sender invalid.

Check the completing domain;

It must advertise a valid completion scheduler.

Handle the case of dependent senders.

Definition at line 18 of file check_continues_on.hpp.

check_scheduler()

template<stdexec::scheduler SchedulerType>

bool Tests::Utils::check_scheduler ( )

consteval

Check that the given type models the stdexec::scheduler concept.

According to https://eel.is/c++draft/exec.sched#1, a valid scheduler must have a scheduler_concept alias. However, as of https://github.com/NVIDIA/stdexec/blob/0e9983599d0c95fca3fd11baa02564eb53fb14f6/include/stdexec/__detail/__schedulers.hpp#L74, it is not checked by stdexec::scheduler.

Related to https://github.com/NVIDIA/stdexec/issues/1406.

According to https://eel.is/c++draft/exec.sched#1, a schedule invocation must return a sender.

Definition at line 10 of file check_scheduler.hpp.

on_device()

template<Kokkos::ExecutionSpace Exec>

bool Tests::Utils::on_device ( )

constexpr

Definition at line 22 of file kokkos.hpp.

show_exec_space_id()

template<Kokkos::ExecutionSpace Exec>

void Tests::Utils::show_exec_space_id	(	const Exec &	exec,
		std::string_view	label = "",
		std::ostream &	out = std::cout )

Definition at line 33 of file kokkos.hpp.
