}

Message meta data. Message passing protocol is build around this structure.

Fields

tx: String

Addr of message sender

rx: String

Addr of message receiver

key: String

Logic key for message processing

kind: MsgKind

Defines what kind of message it is

correlation_id: Uuid

Correlation id is needed for rpc and for message chains

route: Route

Logical message route, receiver are responsible for moving message on.

payload_size: u64

Size of payload, used for deserialization. Also useful for monitoring.

auth_token: Option<String>

Authorization token.

auth_data: Option<Value>

Authorization data.

attachments: Vec<Attachment>

Attachments to message

Implementations

impl MsgMeta

pub fn content_len(&self) -> u64
