Enum AttemptRetryPrerequisite 

Source 
pub enum AttemptRetryPrerequisite {
    None,
    CapacityAvailable,
    ConfigurationChanged,
    QuarantinedDeviceAndEligibleAlternate,
    BackendRecovered,
    EvidenceUnavailable,
}
Expand description

Closed condition that must hold before acting on an AttemptRetryRecovery recommendation.

Variants§

§

None

No prerequisite accompanies success or a do-not-retry recommendation.

§

CapacityAvailable

Capacity evidence permits a new admission after waiting.

§

ConfigurationChanged

The query, capability selection or configured limit has changed.

§

QuarantinedDeviceAndEligibleAlternate

The failed device remains quarantined and another device is eligible.

§

BackendRecovered

Backend recovery completed before a new attempt.

§

EvidenceUnavailable

The sealed evidence cannot establish a recovery prerequisite.
