Struct zenoh_protocol::proto::OpenSyn

    pub lease: Duration,

    pub cookie: ZSlice,
}

Open message

NOTE: 16 bits (2 bytes) may be prepended to the serialized message indicating the total length
      in bytes of the message, resulting in the maximum length of a message being 65_535 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 length of a message must not exceed 65_535 bytes.

The OPEN message is sent on a link to finally open an initialized transport with the peer.

(*)   if T==1 then the lease period is expressed in seconds, otherwise in milliseconds
(**)  the initial sequence number MUST be compatible with the sequence number resolution agreed in the
      InitSyn/InitAck message exchange
(***) the cookie MUST be the same received in the INIT message with A==1 from the corresponding peer

Trait Implementations

impl Clone for OpenSyn

fn clone(&self) -> OpenSyn

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OpenSyn

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Header for OpenSyn

fn header(&self) -> u8

impl PartialEq<OpenSyn> for OpenSyn

fn eq(&self, other: &OpenSyn) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
