Types

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)

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) Total

func (p *Peers) Total() int
