Types

type PersistentStatusHandler

type PersistentStatusHandler struct {
	// contains filtered or unexported fields
}

PersistentStatusHandler is a status handler that will save metrics in storage

func NewPersistentStatusHandler

func NewPersistentStatusHandler(
	marshalizer marshal.Marshalizer,
	uint64ByteSliceConverter typeConverters.Uint64ByteSliceConverter,
) (*PersistentStatusHandler, error)

NewPersistentStatusHandler will return an instance of the persistent status handler
