Struct ParticipantMessageData 

pub struct ParticipantMessageData {
    pub participant_guid: [u8; 16],
    pub kind: u32,
    pub data: Vec<u8>,
}

ParticipantMessageData (DDSI-RTPS 2.5 §9.6.3.1) — Payload des DCPSParticipantMessage-Topics.

Fields

participant_guid: [u8; 16]

16-Byte GUID des Senders (Prefix + EntityId::PARTICIPANT). Auch wenn die Spec “Prefix” sagt, schreiben Cyclone und Fast- DDS hier den vollen Guid; wir folgen.

kind: u32

Liveliness-Kind (siehe PARTICIPANT_MESSAGE_DATA_KIND_*).

data: Vec<u8>

Opaque Token. Bei MANUAL_BY_TOPIC Topic-Hash, sonst leer.

Implementations

impl ParticipantMessageData

pub fn automatic(prefix: GuidPrefix) -> Self

Konstruktor fuer AUTOMATIC-Heartbeat (data leer).

pub fn manual_by_participant(prefix: GuidPrefix) -> Self

Konstruktor fuer MANUAL_BY_PARTICIPANT-Heartbeat (data leer).

pub fn manual_by_topic(prefix: GuidPrefix, topic_token: Vec<u8>) -> Self

Konstruktor fuer ZeroDDS-MANUAL_BY_TOPIC (data = Topic-Token).

pub fn to_cdr(&self, little_endian: bool) -> Result<Vec<u8>, WireError>

Encoded zu CDR-Bytes (mit 4-byte Encapsulation-Header). little_endian = true → ENCAPSULATION_CDR_LE, sonst BE.

Errors

WireError::ValueOutOfRange wenn data.len() > MAX_DATA_LEN.

pub fn from_cdr(bytes: &[u8]) -> Result<Self, WireError>

Decoded aus CDR-Bytes (mit Encapsulation-Header).

Akzeptiert 0x0000/0x0001 (XCDR1 Plain) und 0x0006/0x0007 (XCDR2 Plain). Andere Encapsulation-Kinds → Fehler.

Tolerant gegenueber 12-Byte-Prefix-Only-Kodierung (fuellt mit 0 auf 16 Byte auf).

Errors

• UnsupportedEncapsulation bei nicht-CDR-Encapsulation
• UnexpectedEof wenn Bytes zu kurz fuer Header / Body
• ValueOutOfRange wenn data.len > MAX_DATA_LEN

pub fn prefix(&self) -> GuidPrefix

Liefert den GuidPrefix (erste 12 Byte).

pub fn is_vendor_kind(&self) -> bool

true wenn der kind-Wert vendor-spezifisch ist (MSB gesetzt).

Trait Implementations

impl Clone for ParticipantMessageData

fn clone(&self) -> ParticipantMessageData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParticipantMessageData

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

Formats the value using the given formatter.

impl PartialEq for ParticipantMessageData

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

Tests for self and other values to be equal, and is used by ==.

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

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