Required Methods§

Source

fn build(id: TaskId, context: &str) -> ClResult<Arc<dyn Task<S>>>
where Self: Sized,

Source

fn serialize(&self) -> String

Source

Provided Methods§

Source

fn on_failed<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _state: &'life1 S, _attempts: u16, _last_error: &'life2 str, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Called when the task transitions to Failed after exhausting retries (or on the very first failure when no retry policy is set). Lets the task perform irreversible cleanup — e.g. mark a related domain row as permanently failed — that should not happen on retryable failures. Default: no-op.
