Struct CompensationBuilder 

pub struct CompensationBuilder<'a, S> { /* private fields */ }

Undoes a closure effect. Created by Runtime::compensation.

Implementations

impl<'a, S: EffectStore> CompensationBuilder<'a, S>

pub fn reason(self, reason: impl Into<String>) -> Self

Why the effect is being undone; recorded in the audit trail.

pub fn actor(self, actor: impl Into<String>) -> Self

Who is undoing it, e.g. agent:support-bot.

pub fn retry(self, policy: RetryPolicy) -> Self

The retry policy for compensation attempts; defaults to the runtime’s. Its max_attempts bounds attempts over the compensation’s life.

pub fn attempt_timeout(self, timeout: Duration) -> Self

Gives up waiting for one attempt after timeout, and retries.

pub async fn run<T, F, Fut>( self, compensate: F, ) -> Result<CompensationOutcome, RuntimeError>

where T: DeserializeOwned + Send + 'static, F: Fn(CompensationContext, Option<T>) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<(), EffectFailure>> + Send + 'static,

Undoes the effect with compensate, which receives the effect’s stored output (None if it had none). Calling again after it is undone returns CompensationOutcome::Compensated without running anything.

Errors

Infrastructure failures, an invalid name or key, or no such effect.
