}

Authenticated named-attribute lookup failures.

Variants

Cancelled

Cancellation occurred before a storage boundary.

EmptyBatch

Batch lookup requires at least one name.

TooManyQueries

Batch lookup exceeds its explicit query limit.

WrongRootKind

Root is not an attribute page.

InvalidLimits

Traversal/page limits are invalid.

HeightExceeded

Traversal exceeded the admitted height.

CycleOrAlias

Authenticated graph cycles or aliases.

ChildBoundsMismatch

A parent route does not match child bounds.

InvalidRouting

No child can route the requested name.

AllocationFailed

Bounded scratch allocation failed.

Storage(ObjectStoreError)

Immutable object storage failed.

Decode(CanonicalDecodeError)

Canonical attribute page failed decoding.

Work(WorkError)

Work accounting overflowed or exceeded the admitted budget.

Trait Implementations

impl Debug for AttributeLookupError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for AttributeLookupError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for AttributeLookupError

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.
