Implementations§

Source§

impl InMemoryDurabilityBackend

Source

pub fn new(qos: DurabilityServiceQosPolicy) -> Self

Trait Implementations§

Source§

impl DurabilityBackend for InMemoryDurabilityBackend

Source§

fn store(&self, sample: DurabilitySample) -> Result<()>

Persistiert ein Sample. Read more
Source§

fn replay_for_topic(&self, topic: &str) -> Result<Vec<DurabilitySample>>

Liefert alle gespeicherten Samples fuer ein Topic in der Reihenfolge ihrer Sequence-Number (sortiert pro Instance). Read more
Source§

fn unregister_instance( &self, topic: &str, instance_key: [u8; 16], now: SystemTime, ) -> Result<()>

Markiert eine Instance als unregister, sodass nach service_cleanup_delay die zugehoerigen Samples entfernt werden. now ist die aktuelle Wall-Clock; das eigentliche Loeschen passiert spaeter via Self::cleanup. Read more
Source§

fn cleanup(&self, now: SystemTime) -> Result<usize>

Loescht alle Instanzen, deren unregister-Zeitpunkt + Cleanup- Delay vor now liegt. Liefert die Anzahl entfernter Instanzen. Read more
