Enum OperatorRejection 

#[non_exhaustive]
pub enum OperatorRejection {
    OptimisticConflict {
        current: ExecutionVersion,
    },
    InvalidState {
        status: BatchStatus,
    },
    InstanceCompleted,
    InstanceAbandoned,
    ExecutionAlreadyActive {
        execution_id: JobExecutionId,
        status: BatchStatus,
    },

    UnresolvedRecoveryRequired,
    ExecutionNotFound,
    InstanceNotFound,
    UnsupportedAction,
}

The typed reason one guard rejected an operator action.

A rejection is durable and audited. It carries no user error text, SQL, or credential.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

OptimisticConflict

The supplied expected version lost its compare-and-swap.

Fields

current: ExecutionVersion

The version observed under lock.

InvalidState

The action is not legal from the observed status.

Fields

status: BatchStatus

The status observed under lock.

InstanceCompleted

The logical instance already completed.

InstanceAbandoned

The logical instance is permanently abandoned.

ExecutionAlreadyActive

Another attempt is active or requires explicit recovery.

Fields

execution_id: JobExecutionId

The attempt preventing the action.

status: BatchStatus

Its status observed under lock.

IncompatibleDefinition

The proposed definition cannot interpret the committed checkpoint.

RestartWithoutPriorAttempt

A restart was requested for an instance with no prior attempt.

StartLimitExceeded

The instance-wide start limit for a logical step is exhausted.

UnresolvedRecoveryRequired

Abandoning an ambiguous execution requires an applied recovery decision.

ExecutionNotFound

The targeted execution does not exist.

InstanceNotFound

The targeted logical instance does not exist.

UnsupportedAction

This build cannot apply the requested action.

OperatorAction is #[non_exhaustive], so a caller compiled against a newer definition of it can name an action this build has no effect for. Rejecting is the conservative arm: the request is audited and nothing is applied.
