Types

type PushSync

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

func New

func New(address swarm.Address, blockHash []byte, streamer p2p.StreamerDisconnecter, storer storage.Putter, topology topology.Driver, tagger *tags.Tags, isFullNode bool, unwrap func(swarm.Chunk), validStamp func(swarm.Chunk, []byte) (swarm.Chunk, error), logger logging.Logger, accounting accounting.Interface, pricer pricer.Interface, signer crypto.Signer, tracer *tracing.Tracer, warmupTime time.Duration) *PushSync

func (*PushSync) Metrics

func (s *PushSync) Metrics() []prometheus.Collector

func (*PushSync) Protocol

func (s *PushSync) Protocol() p2p.ProtocolSpec

func (*PushSync) PushChunkToClosest

func (ps *PushSync) PushChunkToClosest(ctx context.Context, ch swarm.Chunk) (*Receipt, error)

PushChunkToClosest sends chunk to the closest peer by opening a stream. It then waits for a receipt from that peer and returns error or nil based on the receiving and the validity of the receipt.

type PushSyncer

type PushSyncer interface {
	PushChunkToClosest(ctx context.Context, ch swarm.Chunk) (*Receipt, error)
}

type Receipt

type Receipt struct {
	Address   swarm.Address
	Signature []byte
	BlockHash []byte
}
