Kind describes the kind of instrument.
type Kind int8
ValueRecorderKind indicates a ValueRecorder instrument.

)
Synchronous returns whether this is a synchronous kind of instrument.
func ( Kind) () bool {
	switch  {
	case CounterKind, UpDownCounterKind, ValueRecorderKind:
		return true
	}
	return false
}
Asynchronous returns whether this is an asynchronous kind of instrument.
func ( Kind) () bool {
	return !.Synchronous()
}
Adding returns whether this kind of instrument adds its inputs (as opposed to Grouping).
func ( Kind) () bool {
	switch  {
	case CounterKind, UpDownCounterKind, SumObserverKind, UpDownSumObserverKind:
		return true
	}
	return false
}
Adding returns whether this kind of instrument groups its inputs (as opposed to Adding).
func ( Kind) () bool {
	return !.Adding()
}
Monotonic returns whether this kind of instrument exposes a non-decreasing sum.
func ( Kind) () bool {
	switch  {
	case CounterKind, SumObserverKind:
		return true
	}
	return false
}
Cumulative returns whether this kind of instrument receives precomputed sums.
func ( Kind) () bool {
	return .Adding() && .Asynchronous()
