Struct zenoh_protocol::proto::Sync

pub struct Sync {
    pub ch: Channel,
    pub sn: ZInt,
    pub count: Option<ZInt>,
}

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 SYNC message allows to signal the corresponding peer the sequence number of the next message to be transmitted on the reliable or best-effort channel. In the case of reliable channel, the peer can optionally include the number of unacknowledged messages. A SYNC sent on the reliable channel triggers the transmission of an ACKNACK message.

• if R==1 then the SYNC concerns the reliable channel, otherwise the best-effort channel.

Trait Implementations

impl Clone for Sync

fn clone(&self) -> Sync

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sync

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

Formats the value using the given formatter.

impl PartialEq<Sync> for Sync

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

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

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

This method tests for !=.
