Enum ChangeKind 

pub enum ChangeKind {
    Alive,
    AliveFiltered,
    NotAliveDisposed,
    NotAliveUnregistered,
    NotAliveDisposedUnregistered,
}

Art eines Cache-Eintrags (DDSI-RTPS §8.2.1.2 / §8.7.2.2.2).

Variants

Alive

Gueltiges Sample, von DDS-DataReader-Filter akzeptiert.

AliveFiltered

Gueltiges Sample, vom Reader-side Filter (TIME_BASED_FILTER / ContentFilteredTopic) verworfen — bleibt aber im NACK-Pfad “available”, damit Reliable-Writer es nicht erneut sendet (filteredCount-Zaehler in ChangeFromWriter).

NotAliveDisposed

dispose-Marker.

NotAliveUnregistered

unregister-Marker.

NotAliveDisposedUnregistered

Kombinierter dispose+unregister.

Implementations

impl ChangeKind

pub fn is_relevant(self) -> bool

Spec §8.4.10.5 — is_relevant true fuer alle Live-Kinds; nur AliveFiltered ist explizit nicht relevant fuer den DDS- User-API-Path (zaehlt aber im NACK-Pfad als “received”).

pub fn is_alive_kind(self) -> bool

Spec §8.4.10.5 — is_alive_kind umfasst Alive + AliveFiltered.

impl Clone for ChangeKind

fn clone(&self) -> ChangeKind

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

Performs copy-assignment from source.

impl Debug for ChangeKind

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

Formats the value using the given formatter.

impl PartialEq for ChangeKind

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