Function `std.datetime.measureTime`

The old benchmarking functionality in std.datetime (which uses TickDuration) has been deprecated. Use what's in std.datetime.stopwatch instead. It uses MonoTime and Duration. Note that measureTime has not been ported over, because it's a trivial wrapper around StopWatch. See StopWatch. This symbol will be removed from the documentation in October 2018 and fully removed from Phobos in October 2019.


						
				auto auto measureTime(alias func)() @safe
				

				if (isSafe!(()
{
StopWatch sw;
unaryFun!func(sw.peek());
}
));
				

				

				auto auto measureTime(alias func)()
				

				if (!isSafe!(()
{
StopWatch sw;
unaryFun!func(sw.peek());
}
));

Function for starting to a stop watch time when the function is called and stopping it when its return value goes out of scope and is destroyed.

When the value that is returned by this function is destroyed, func will run. func is a unary function that takes a TickDuration.

Example

{
    auto mt = measureTime!((TickDuration a)
        { /+ do something when the scope is exited +/ });
    // do something that needs to be timed
}

// functionally equivalent to the above
{
    auto sw = StopWatch(Yes.autoStart);
    scope(exit)
    {
        TickDuration a = sw.peek();
        /+ do something when the scope is exited +/
    }
    // do something that needs to be timed
}
