Types

type ChannelAuthConfig added in v0.29.0 

type ChannelAuthConfig struct {
	// AuthorizedRoles list of roles authorized to send this message on the channel.

	// AllowedProtocols list of protocols the message is allowed to be sent on. Currently AllowedProtocols is expected to have
	// exactly one element in the list. This is due to the fact that currently there are no messages that are used with both protocols aside from TestMessage.
	AllowedProtocols Protocols
}

type ProtocolType added in v0.30.0 

type ProtocolType string

ProtocolType defines the type of the protocol a message is sent over. Currently, we have two types of protocols: - unicast: a message is sent to a single node through a direct connection. - pubsub: a message is sent to one or more nodes through a pubsub channel. 

const (
	// ProtocolTypeUnicast is protocol type for unicast messages.
	ProtocolTypeUnicast ProtocolType = "unicast"
	// ProtocolTypePubSub is the protocol type for pubsub messages.
	ProtocolTypePubSub ProtocolType = "pubsub"
)
