pkg/ingester/client/compat.go:308–314

LabelsToKeyString is used to form a string to be used as the hashKey. Don't print, use l.String() for printing.

(l labels.Labels)

// LabelsToKeyString is used to form a string to be used as
// the hashKey. Don't print, use l.String() for printing.
func LabelsToKeyString(l labels.Labels) string {
	// We are allocating 1024, even though most series are less than 600b long.
	// But this is not an issue as this function is being inlined when called in a loop
	// and buffer allocated is a static buffer and not a dynamic buffer on the heap.
	b := make([]byte, 0, 1024)
	return string(l.Bytes(b))
