type AppSender added in v1.5.3 

type AppSender interface {
	// Send an application-level request
	SendAppRequest(nodeIDs ids.ShortSet, chainID ids.ID, requestID uint32, deadline time.Duration, appRequestBytes []byte) []ids.ShortID

type Sender 

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

Sender is a wrapper around an ExternalSender. Messages to this node are put directly into router rather than being sent over the network via the wrapped ExternalSender. Sender registers outbound requests with router so that router fires a timeout if we don't get a response to the request.

func (*Sender) Context 

func (s *Sender) Context() *snow.Context

Context of this sender

func (*Sender) Initialize 

func (s *Sender) Initialize(
	ctx *snow.Context,
	sender ExternalSender,
	router router.Router,
	timeouts *timeout.Manager,
	metricsNamespace string,
	metricsRegisterer prometheus.Registerer,
) error

Initialize this sender
