Functions

func IsUnknownMsgTypeErr 

func IsUnknownMsgTypeErr(err error) bool

IsUnknownMsgTypeErr returns whether an error is UnknownMsgTypeErr

func NewUnauthorizedProtocolError 

func NewUnauthorizedProtocolError(p Protocol) error

NewUnauthorizedProtocolError returns ErrUnauthorizedUnicastOnChannel or ErrUnauthorizedPublishOnChannel depending on the protocol provided.

Types

type ChannelAuthConfig 

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 Message 

type Message struct {
	ChannelID            string   `protobuf:"bytes,1,opt,name=ChannelID,proto3" json:"ChannelID,omitempty"`

	XXX_NoUnkeyedLiteral struct{} `json:"-"`
	XXX_unrecognized     []byte   `json:"-"`
	XXX_sizecache        int32    `json:"-"`
}
