Function std.datetime.measureTime
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
core.time.TickDuration.
Prototype
auto measureTime(alias func)();
Examples
{
auto mt = measureTime!((TickDuration a)
{ /+ do something when the scope is exited +/ });
// do something that needs to be timed
}
which is functionally equivalent to
{
auto sw = StopWatch(AutoStart.yes);
scope(exit)
{
TickDuration a = sw.peek();
/+ do something when the scope is exited +/
}
// do something that needs to be timed
}
