Function std.datetime.stopwatch.StopWatch.this
Constructs a StopWatch. Whether it starts immediately depends on the
AutoStart
argument.
If StopWatch
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));
