Struct DeliveredSample 

pub struct DeliveredSample {
    pub writer_guid: Guid,
    pub sequence_number: SequenceNumber,
    pub payload: Arc<[u8]>,
    pub kind: ChangeKind,
    pub key_hash: Option<[u8; 16]>,
}

Ein an die Applikation ausgelieferter Sample.

Fields

writer_guid: Guid

GUID des Writers, von dem der Sample kommt. Macht Multi-Writer- Deduplication im Caller moeglich.

sequence_number: SequenceNumber

Sequence-Number im Writer.

payload: Arc<[u8]>

Serialisierter Payload (Zero-Copy via Arc::clone aus dem Cache). Nutzlast.

kind: ChangeKind

Spec §8.2.1.2 ChangeKind — Alive fuer normale Samples, NotAliveDisposed / NotAliveUnregistered / NotAliveDisposedUnregistered fuer Lifecycle-Marker, die der Writer per dispose/unregister_instance versendet hat. Spec §9.6.3.9 PID_STATUS_INFO im Inline-QoS.

key_hash: Option<[u8; 16]>

PID_KEY_HASH aus dem Inline-QoS (Spec §9.6.4.8). Bei Lifecycle-Markern ist das die Identitaet der disposed/ unregistered Instanz; bei keyed-Topic-ALIVE-Samples optional (manche Vendors senden Inline-Hash, manche nicht). None wenn der Writer keinen Hash inline mitliefert (typisch fuer keyless Topics).

Trait Implementations

impl Clone for DeliveredSample

fn clone(&self) -> DeliveredSample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeliveredSample

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

Formats the value using the given formatter.

impl PartialEq for DeliveredSample

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