Public Class Stopwatch

Measures how long goes by while it runs, over as many starts and stops as it has.

Examples

Local start = Instant.FromNanoseconds(0)
Local watch = Stopwatch.StartNew(start)
Expect(watch.ElapsedAt(Instant.FromNanoseconds(1_500_000)) == 1500.Microseconds)
watch.Stop(Instant.FromNanoseconds(2_000_000))
Expect(watch.Elapsed == 2.Milliseconds && !watch.IsRunning)
