func (*ReceivedMessage) Fields

func (p *ReceivedMessage) Fields() log.Fields

type Service

type Service interface {
	supervisor.Service
	Transport
}

Service implements a mechanism for exchanging messages between Oracles.

type Transport

type Transport interface {
	// Broadcast sends a message with a given topic.
	Broadcast(topic string, message Message) error

	// Messages returns a channel for incoming messages. A new channel is
	// created for each call, therefore this method should not be used in
	// loops. In case of an error, an error will be returned in the
	// ReceivedMessage structure.
	Messages(topic string) <-chan ReceivedMessage
}
