View/edit binary Protocol Buffers messages

ViewPacket is one message of a session. Fields are only ever added, never renumbered, retyped or removed, and a release ignores the fields a later one adds.

• string sessionID = 1

• string contextID = 2

• int32 status = 3

• bytes payload = 4

• string caller = 5

  caller is the Go type path of the view that opened the session. The responder is found by protocol when it is set and known, and by caller otherwise.

• bytes versions = 6

  versions is an encoded preamble.ComponentVersions, set on each message of a session the initiator opened: the version of each component's formats the session uses, the same on every message. The responder's messages carry none. It is bytes, so that a receiver checks its size, at most 4 KiB like the preamble, before it decodes the list.

• string protocol = 7

  protocol is the stable name "<component>/<name>" of the protocol the session runs, set on each initiator message when the initiator view declares one.
