Sync 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 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 Header for Sync

fn header(&self) -> u8

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: &Rhs) -> bool

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

impl Eq for Sync

impl StructuralEq for Sync

impl StructuralPartialEq for Sync
