namespace hpx

struct launch : public detail::policy_holder<>

#include <launch_policy.hpp>

Launch policies for hpx::async etc.

Public Functions

inline constexpr launch() noexcept

Default constructor. This creates a launch policy representing all possible launch modes

inline constexpr launch(detail::async_policy p) noexcept

Create a launch policy representing asynchronous execution.

inline constexpr launch(detail::fork_policy p) noexcept

Create a launch policy representing asynchronous execution. The new thread is executed in a preferred way

inline constexpr launch(detail::sync_policy p) noexcept

Create a launch policy representing synchronous execution.

inline constexpr launch(detail::deferred_policy p) noexcept

Create a launch policy representing deferred execution.

inline constexpr launch(detail::apply_policy p) noexcept

Create a launch policy representing fire and forget execution.

template<typename F>
inline constexpr launch(detail::select_policy<F> const &p) noexcept

Create a launch policy representing fire and forget execution.

template<typename Launch, typename Enable = std::enable_if_t<hpx::traits::is_launch_policy_v<Launch>>>
inline constexpr launch(Launch l, threads::thread_priority priority, threads::thread_stacksize stacksize, threads::thread_schedule_hint hint) noexcept

Public Static Attributes
