Module protocol 

Protocol types and constants mirrored from protocol.md and the TS package.

These are the source-of-truth structures for the Rust encoder/decoder. The ProtocolMessage enum aggregates all message variants.

Structs

BatchId

8-byte batch ID for fragmenting. On the wire this is exactly 8 raw bytes.

Enums

CrdtType

CRDT types supported by the wire format.

JoinErrorCode

Error codes for JoinError (0x02).

MessageType

Message type tags as defined in protocol.md

Permission

Permission returned by a successful JoinResponse.

ProtocolMessage

All protocol messages as a single enum. Each variant includes the common crdt magic and room_id as part of the struct fields.

UpdateErrorCode

Error codes for UpdateError (0x06).

Constants

MAGIC

Reserved library magic string, aligned with the TypeScript library. Not part of the message envelope; included for parity.
