Backend-neutral aggregate cache ownership failure.

Variants

InvalidLimits(&'static str)

Aggregate limits had no device or transfer capacity.

DuplicateManager

A manager identity was registered more than once.

Fields

manager: u64

Duplicate manager identity.

UnknownManager

Occupancy was published for an unregistered manager.

Fields

manager: u64

Missing manager identity.

BudgetExceeded

Aggregate cache accounting exceeded one finite resource limit.

Fields

resource: CachePoolResource

Exhausted resource axis.

required: u64

Aggregate bytes required.

budget: u64

Finite pool budget.

AccountingOverflow

Checked ownership accounting overflowed.

Fields

operation: &'static str

Stable accounting transition.

Poisoned

Shared ownership state was poisoned by a panic.

Trait Implementations

impl Clone for CachePoolError

fn clone(&self) -> CachePoolError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CachePoolError

impl Eq for CachePoolError

impl Error for CachePoolError

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.
