Function `std.datetime.stopwatch.StopWatch.this`

Constructs a StopWatch. Whether it starts immediately depends on the AutoStart argument.


						
				ref this
				(
				

				  Flag!("autoStart") autostart
				

				) nothrow @nogc @safe;

If StopWatch.init is used, then the constructed StopWatch isn't running (and can't be, since no constructor ran).

Example

import core.thread : Thread;

{
    auto sw = StopWatch(AutoStart.yes);
    assert(sw.running);
    Thread.sleep(usecs(1));
    assert(sw.peek() > Duration.zero);
}
{
    auto sw = StopWatch(AutoStart.no);
    assert(!sw.running);
    Thread.sleep(usecs(1));
    writeln(sw.peek()); // Duration.zero
}
{
    StopWatch sw;
    assert(!sw.running);
    Thread.sleep(usecs(1));
    writeln(sw.peek()); // Duration.zero
}

writeln(StopWatch.init); // StopWatch(AutoStart.no)
assert(StopWatch.init != StopWatch(AutoStart.yes));
