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.

fn clone(&self) -> Sync

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sync

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