Authenticated file-table frontier failures.

Variants

Cancelled

Cooperative cancellation occurred before the next storage boundary.

EmptyBatch

Batch lookup requires at least one identity.

TooManyQueries

Batch lookup exceeds its explicit query limit.

WrongRootKind

Root is not a file-table page.

InvalidHeightLimit

Page-height limit must be non-zero.

Cycle

Child graph references an ancestor.

HeightExceeded

Traversal did not reach a leaf within the admitted height.

InvalidRouting

Internal routing could not select a child.

ChildBoundsMismatch

Parent lower/upper routing bounds disagree with the selected child.

AllocationFailed

A bounded batch scratch allocation failed.

Storage(ObjectStoreError)

Immutable-object backend failed.

Decode(CanonicalDecodeError)

Canonical page failed decoding or validation.

Work(WorkError)

Exact work exceeded or overflowed its budget.

Trait Implementations

impl Debug for FileRecordReadError

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

Formats the value using the given formatter.

impl Display for FileRecordReadError

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

Formats the value using the given formatter.

impl Error for FileRecordReadError

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.
