Types

type Agent

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

Agent is the agent to help the blockchain node connect into the P2P networks and send/receive messages

func NewAgent

func NewAgent(cfg Network, chainID uint32, genesisHash hash.Hash256, broadcastHandler HandleBroadcastInbound, unicastHandler HandleUnicastInboundAsync) *Agent

NewAgent instantiates a local P2P agent instance

func (*Agent) BroadcastOutbound

func (p *Agent) BroadcastOutbound(_ context.Context, msg proto.Message) (err error)

BroadcastOutbound sends a broadcast message to the whole network

func (*Agent) Info

func (p *Agent) Info() (peer.AddrInfo, error)

Info returns agents' peer info.

func (*Agent) Neighbors

func (p *Agent) Neighbors(ctx context.Context) ([]peer.AddrInfo, error)

Neighbors returns the neighbors' peer info

func (*Agent) QosMetrics

func (p *Agent) QosMetrics() *Qos

QosMetrics returns the Qos metrics

func (*Agent) Self

func (p *Agent) Self() ([]multiaddr.Multiaddr, error)

Self returns the self network address

func (*Agent) Start

func (p *Agent) Start(ctx context.Context) error

Start connects into P2P network

func (*Agent) Stop

func (p *Agent) Stop(ctx context.Context) error

Stop disconnects from P2P network

func (*Agent) UnicastOutbound

func (p *Agent) UnicastOutbound(_ context.Context, peer peer.AddrInfo, msg proto.Message) (err error)

UnicastOutbound sends a unicast message to the given address

type HandleBroadcastInbound

type HandleBroadcastInbound func(context.Context, uint32, string, proto.Message)

HandleBroadcastInbound handles broadcast message when agent listens it from the network

type HandleUnicastInboundAsync

type HandleUnicastInboundAsync func(context.Context, uint32, peer.AddrInfo, proto.Message)

HandleUnicastInboundAsync handles unicast message when agent listens it from the network

type Network

type Network struct {
	Host           string   `yaml:"host"`
	Port           int      `yaml:"port"`
	ExternalHost   string   `yaml:"externalHost"`
	ExternalPort   int      `yaml:"externalPort"`
	BootstrapNodes []string `yaml:"bootstrapNodes"`
	MasterKey      string   `yaml:"masterKey"` // master key will be PrivateKey if not set.
	// RelayType is the type of P2P network relay. By default, the value is empty, meaning disabled. Two relay types
	// are supported: active, nat.
	RelayType         string              `yaml:"relayType"`
	ReconnectInterval time.Duration       `yaml:"reconnectInterval"`
