Struct zenoh_protocol::proto::Open

    pub version: u8,

NOTE: 16 bits (2 bytes) may be prepended to the serialized message indicating the total lenght in bytes of the message, resulting in the maximum lenght of a message being 65_536 bytes. This is necessary in those stream-oriented transports (e.g., TCP) that do not preserve the boundary of the serialized messages. The length is encoded as little-endian. In any case, the lenght of a message must not exceed 65_535 bytes.

The OPEN message is sent on a specific Locator to initiate a session with the peer associated with that Locator.

(*) The Initial SN must be bound to the proposed SN Resolution. Otherwise the OPEN message is consmsg::idered invalid and it should be discarded by the recipient of the OPEN message. (**) In case of the Accepter Peer negotiates a smaller SN Resolution (see ACCEPT message) and the proposed Initial SN results to be out-of-bound, the new Agreed Initial SN is calculated according to the following modulo operation: Agreed Initial SN := (Initial SN_Open) mod (SN Resolution_Accept)
