Types

type PeerStats added in v1.4.0 

type PeerStats struct {
	ID       peer.ID
	Success  int
	Failures int
	Latency  time.Duration
}

func (*PeerStats) MarshalLogObject added in v1.4.0 

func (p *PeerStats) MarshalLogObject(enc zapcore.ObjectEncoder) error

type Peers 

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

func New 

func New() *Peers

func (*Peers) Add 

func (p *Peers) Add(id peer.ID) bool

func (*Peers) Delete 

func (p *Peers) Delete(id peer.ID)

func (*Peers) OnFailure 

func (p *Peers) OnFailure(id peer.ID, size int, latency time.Duration)

func (*Peers) OnLatency 

func (p *Peers) OnLatency(id peer.ID, size int, latency time.Duration)

OnLatency updates average peer and global latency.

func (*Peers) SelectBest 

func (p *Peers) SelectBest(n int) []peer.ID

SelectBest selects at most n peers sorted by responsiveness and latency.

SelectBest parametrized by N because sync protocol relies on receiving data from redundant connections to guarantee that it will get complete data set. If it doesn't get complete data set it will have to fallback into hash resolution, which is generally more expensive.

func (*Peers) SelectBestFrom 

func (p *Peers) SelectBestFrom(peers []peer.ID) peer.ID

SelectBest peer with preferences.

func (*Peers) Stats added in v1.4.0 

func (p *Peers) Stats() Stats

func (*Peers) Total 

func (p *Peers) Total() int

type Stats added in v1.4.0 

type Stats struct {
	Total                int
	GlobalAverageLatency time.Duration
	BestPeers            []PeerStats
}

func (*Stats) MarshalLogObject added in v1.4.0 

func (s *Stats) MarshalLogObject(enc zapcore.ObjectEncoder) error
