Types

type Message

type Message interface {
	// MarshallBinary serializes the message into a byte slice.
	MarshallBinary() ([]byte, error)

	// UnmarshallBinary deserializes the message from a byte slice.
	UnmarshallBinary([]byte) error
}

Message is a message that can be sent over transport.

type ReceivedMessage

type ReceivedMessage struct {
	// Message contains the message content. It is nil when the Error field
	// is not nil.
	Message Message

	// Author is the author of the message.
	Author []byte

	// Data contains an optional data associated with the message. A type of
	// the data is different depending on a transport implementation.
	Data any

	// Error contains an optional error returned by transport layer.
	Error error
}

ReceivedMessage contains a Message received from Transport.

type Transport

type Transport interface {
	supervisor.Service

	// 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
}

Transport implements a mechanism for exchanging messages between Oracles.
