Struct zenoh_protocol::proto::Attachment

pub struct Attachment {
    pub buffer: ZBuf,
}

Attachment decorator

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 Attachment can decorate any message (i.e., TransportMessage and ZenohMessage) and it allows to
append to the message any additional information. Since the information contained in the
Attachement is relevant only to the layer that provided them (e.g., Transport, Zenoh, User) it
is the duty of that layer to serialize and de-serialize the attachment whenever deemed necessary.
The attachement always contains serialized properties.

Implementations

impl Attachment

pub fn new(buffer: ZBuf) -> Attachment

Trait Implementations

impl Clone for Attachment

fn clone(&self) -> Attachment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Attachment

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

Formats the value using the given formatter.

impl Header for Attachment

fn header(&self) -> u8

impl PartialEq<Attachment> for Attachment

fn eq(&self, other: &Attachment) -> 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.
