Function Documentation

Pend()

template<typename... Pendables>

Poll< TupleOfOutputRvalues > pw::async2::Join< Pendables >::Pend ( Context &  cx )

inline

Attempts to complete all of the pendables, returning Ready with their results if all are complete.

Select()

template<typename... Pendables>

auto pw::async2::Select	(	Context &	cx,
		Pendables &&...	pendables
	)

Returns the result of the first of the provided pendables which completes.

This Select function is intended for single use only. To iterate over all ready pendables, use Selector directly.

VisitSelectResult()

template<typename ResultVariant , typename AllPendablesCompletedHandler , typename... ReadyHandler>

void pw::async2::VisitSelectResult	(	ResultVariant &&	variant,
		AllPendablesCompletedHandler &&	on_all_pendables_completed,
		ReadyHandler &&...	on_ready
	)

Helper for interacting with a ResultVariant returned by a call to Select. See Selector documentation for example usage.
