Struct WorkerPreparationFailure 

pub struct WorkerPreparationFailure<Role, Worker, Plan, WorkerRejection, SourceRejection> { /* private fields */ }

Complete operating worker-preparation failure emitted by a fixed supervisor.

The worker source is not stored here. It returns separately to the supervisor’s recovery policy. Semantic roles are exposed by reference so they need not implement Clone.

Implementations

impl<Role, Worker, Plan, WorkerRejection, SourceRejection> WorkerPreparationFailure<Role, Worker, Plan, WorkerRejection, SourceRejection>

pub fn role(&self) -> &Role

Inspect the recovery-triggering semantic role.

pub fn reason( &self, ) -> WorkerPreparationFailureReason<'_, Role, WorkerRejection, SourceRejection>

Inspect the exact failure alternative without exposing stored role names.

pub fn prepared( &self, ) -> impl ExactSizeIterator<Item = (&Role, &WorkerSubmission<Worker, Plan>)>

Inspect every worker prepared before the failure in selection order.

pub fn remaining_roles(&self) -> impl ExactSizeIterator<Item = &Role>

Inspect every selected role left untouched after the failure.
