Guard()

template<std::invocable<> F>

auto nc::task::Guard	(	ExceptionContext &	context,
		F &&	func
	)

Wrap a callable in a try-catch targeting a TaskGraph's ExceptionContext.

Template Parameters

F	A callable of the form void(*)().

Parameters

context	The ExceptionContext of the TaskGraph the callable will be scheduled on.
func	The callable to guard.

Returns

A lambda wrapping the callable or the callable itself, depending on the noexcept specification of func.

Individual tasks added through TaskGraph::Add() are automatically guarded if they do not satisfy std::is_nothrow_invocable. Explicit task guarding is needed only on tasks placed in a tf::Taskflow that will be later composed into the primary TaskGraph.
