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

type ConnectionInfo 

type ConnectionInfo struct {
	ID       common.PKIidType
	Auth     *AuthInfo
	Identity api.PeerIdentityType
	Endpoint string
}

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

func (*ConnectionInfo) String 

func (c *ConnectionInfo) String() string

String returns a string representation of this ConnectionInfo

type ReceivedMessage 

type ReceivedMessage interface {
	// Respond sends a GossipMessage to the origin from which this ReceivedMessage was sent from
	Respond(msg *gossip.GossipMessage)

	// 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
	// An ack can receive an error that indicates that the operation related
	// to the message has failed
	Ack(err error)
}

ReceivedMessage is a GossipMessage wrapper that enables the user to send a message to the origin from which the ReceivedMessage was sent from. It also allows to know the identity of the sender, to obtain the raw bytes the GossipMessage was un-marshaled from, and the signature over these raw bytes.

	*gossip.Envelope
	*gossip.GossipMessage
}

SignedGossipMessage contains a GossipMessage and the Envelope from which it came from

func EnvelopeToGossipMessage
