Functions

func EventId added in v0.32.0 

func EventId(channel channels.Channel, payload []byte) (hash.Hash, error)

EventId computes the event ID for a given channel and payload (i.e., the hash of the payload and channel). All errors returned by this function are benign and should not cause the node to crash. It errors if the hash function fails to hash the payload and channel.

func IsUnknownMsgTypeErr added in v0.27.0 

func IsUnknownMsgTypeErr(err error) bool

IsUnknownMsgTypeErr returns whether an error is UnknownMsgTypeErr

func MessageType added in v0.32.0 

func MessageType(decodedPayload interface{}) string

MessageType returns the type of the message payload.

func NewUnauthorizedProtocolError added in v0.29.0 

func NewUnauthorizedProtocolError(p ProtocolType) error

NewUnauthorizedProtocolError returns ErrUnauthorizedUnicastOnChannel or ErrUnauthorizedPublishOnChannel depending on the protocol provided.

Types

type ChannelAuthConfig added in v0.29.0 

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

	// 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 IncomingMessageScope added in v0.32.0 

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

func NewIncomingScope added in v0.32.0 

func NewIncomingScope(originId flow.Identifier, protocol ProtocolType, msg *Message, decodedPayload interface{}) (*IncomingMessageScope, error)

  • ErrUnauthorizedRole: the role is not included in the message's list of authorized roles for the provided channel

	protocolType ProtocolType) (*OutgoingMessageScope, error)

NewOutgoingScope creates a new outgoing message scope. All errors returned by this function are benign and should not cause the node to crash. It errors if the encoder fails to encode the payload into a protobuf message, or if the number of target IDs does not match the protocol type (i.e., unicast messages should have exactly one target ID, while pubsub messages should have at least one target ID).

const (
	// ProtocolTypeUnicast is protocol type for unicast messages.
	ProtocolTypeUnicast ProtocolType = "unicast"
