Struct InvalidationSaga 

pub struct InvalidationSaga {
    pub unit_id: String,
    pub targets: Vec<InvalidationTarget>,
    /* private fields */
}

Cross-partition best-effort invalidation fan-out unit.

Fields

unit_id: String

Stable outbox unit id.

targets: Vec<InvalidationTarget>

Fan-out targets.

Implementations

impl InvalidationSaga

pub fn new(unit_id: impl Into<String>, targets: Vec<InvalidationTarget>) -> Self

Create a saga.

pub fn dispatch_target(&mut self, target: &InvalidationTarget) -> bool

Dispatch one target idempotently. Returns true only for the first effect.

pub fn pending(&self) -> usize

Return pending target count.

pub fn is_complete(&self) -> bool

Return whether every target has been applied.

pub fn idempotency_key(&self, target: &InvalidationTarget) -> String

Return the stable idempotency key for a target.

Trait Implementations

impl Clone for InvalidationSaga

fn clone(&self) -> InvalidationSaga

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidationSaga

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InvalidationSaga

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for InvalidationSaga

impl PartialEq for InvalidationSaga

fn eq(&self, other: &InvalidationSaga) -> 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 InvalidationSaga

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
