    DuplicateBlock(CacheBlockId),
    MissingBlock(CacheBlockId),
    DuplicateRemoval,
    BlockLeased(CacheBlockId),
    UnexpectedLeaseCount {
        id: CacheBlockId,

}

Invalid backend-neutral cache ownership transition.

Variants

DuplicateBlock(CacheBlockId)

A block identity was registered more than once.

MissingBlock(CacheBlockId)

A requested block is not registered.

DuplicateRemoval

A removal list repeated one identity.

BlockLeased(CacheBlockId)

An operation required an unleased block.

UnexpectedLeaseCount

A transactional replacement observed a different lease count.

Fields

id: CacheBlockId

Stable block identity.

expected: usize

Required exact ownership count.

actual: usize

Observed exact ownership count.

LeaseOverflow(CacheBlockId)

Lease acquisition exceeded addressable ownership.

LeaseUnderflow(CacheBlockId)

A backend released a lease it did not own.

AccessClockOverflow

The stable access clock exhausted its range.

Trait Implementations

impl Eq for CacheLifecycleError

impl Error for CacheLifecycleError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for CacheLifecycleError

fn eq(&self, other: &CacheLifecycleError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
