Types

type AuthInfo

type AuthInfo struct {
	SignedData []byte
	Signature  []byte
}

AuthInfo represents the authentication data that was provided by the remote peer at the connection time

	Endpoint string
}

ConnectionInfo represents information about the remote peer that sent a certain ReceivedMessage

func (*ConnectionInfo) String

type ReceivedMessage

type ReceivedMessage interface {
	// Respond sends a GossipMessage to the origin from which this ReceivedMessage was sent from

	// GetGossipMessage returns the underlying GossipMessage
	GetGossipMessage() *SignedGossipMessage

	// GetSourceMessage Returns the Envelope the ReceivedMessage was
	// constructed with
	GetSourceEnvelope() *gossip.Envelope

	// GetConnectionInfo returns information about the remote peer
	// that sent the message
	GetConnectionInfo() *ConnectionInfo

	// Ack returns to the sender an acknowledgement for the message
