Struct InvalidationEvent 

pub struct InvalidationEvent {
    pub ns: Namespace,
    pub key: StructuredKey,
    pub generation: u64,
    pub message_id: u64,
    pub applied_region: Option<RegionId>,

Invalidation event streamed to remote near-caches.

Fields

ns: Namespace

Namespace.

key: StructuredKey

Structured key.

generation: u64

B1 source generation.

message_id: u64

B1 message id.

applied_region: Option<RegionId>

Region where the event was applied.

value: Option<Vec<u8>>

Optional value, gated by residency.

residency_degraded: bool

Whether value was stripped by residency.

affects_subscriber_view: bool

Whether this event affects a subscriber’s tracked cross-region view.

Implementations

impl InvalidationEvent

pub fn new( ns: Namespace, key: StructuredKey, generation: u64, message_id: u64, ) -> Self

Create an invalidation event.

pub fn applied_in(self, region: RegionId) -> Self

Attach applied region.

pub fn with_value(self, value: Vec<u8>) -> Self

Attach an optional value.

pub fn affects_subscriber_view(self) -> Self

Mark that a cross-region invalidation affects the subscriber’s tracked view.

pub fn watermark(&self) -> Watermark

Return event watermark.

pub fn should_deliver_to(&self, region: Option<&RegionId>) -> bool

Return whether this event should be delivered for a region filter.

pub fn residency_gated(self, value_allowed: bool) -> Self

Enforce residency for include-value streams.

Trait Implementations

impl Clone for InvalidationEvent

fn clone(&self) -> InvalidationEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidationEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InvalidationEvent

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for InvalidationEvent

impl PartialEq for InvalidationEvent

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

impl Serialize for InvalidationEvent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
