func NopMetrics 

func NopMetrics() *Metrics

NopMetrics returns no-op Metrics.

func PrometheusMetrics 

func PrometheusMetrics(namespace string, labelsAndValues ...string) *Metrics

PrometheusMetrics returns Metrics build using Prometheus client library. Optionally, labels can be provided along with their values ("foo", "fooValue").

type SyncPattern 

type SyncPattern uint
const (
	// SyncPattern is the work pattern of BlockPool.
	// 1. Mute: will only answer subscribe requests from others, will not sync from others or from consensus channel.
	// 2. Hot:  handle subscribe requests from other peer as a publisher, also subscribe block messages
	//    from other peers as a subscriber.
	// 3. Consensus: handle subscribe requests from other peer as a publisher, but subscribe block message from
	//    consensus channel.
	// The viable transitions between are:
	//                                Hot --> Consensus
	//                                 ^    ^
	//                                 |   /
