Variables

var (
	// DefaultRegisterer and DefaultGatherer are the implementations of the
	// prometheus Registerer and Gatherer interfaces that all metrics operations
	// will use. They are variables so that packages that embed this library can
	// replace them at runtime, instead of having to pass around specific
	// registries.
