StopWatch.this

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

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

struct StopWatch

Examples

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));
    assert(sw.peek() == Duration.zero);
}
{
    StopWatch sw;
    assert(!sw.running);
    Thread.sleep(usecs(1));
    assert(sw.peek() == Duration.zero);
}

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