Enum CacheIoExecutionStateError 

pub enum CacheIoExecutionStateError {
    ZeroCapacity,
    UnknownOperation,
    InvalidAdmission,
    InvalidAdmissionRollback,
    InvalidStart,
    InvalidCompletion,
    OperationStillOwned,
}

Invalid cache I/O executor lifecycle use.

Variants

ZeroCapacity

Bounded I/O admission requires at least one slot.

UnknownOperation

The exact operation key was never prepared or was already retired.

InvalidAdmission

Admission was attempted from a non-prepared phase.

InvalidAdmissionRollback

Physical enqueue rollback did not own an admitted operation.

InvalidStart

The physical executor received an operation from an invalid phase.

InvalidCompletion

Completion did not correspond to a physically executing operation.

OperationStillOwned

Retirement preceded physical dequeue or exact completion.
