}

Stable authenticated blob-read errors.

Variants

Cancelled

Cooperative cancellation occurred before the next storage boundary.

TraversalState

The private resumable reader entered an impossible transition.

WrongRootKind

Root has the wrong typed object class.

InvalidRange

Requested range overflows or exceeds the blob.

InvalidLimits

Decode and traversal limits are invalid or unrepresentable.

AllocationFailed

Bounded output, decode, or traversal scratch allocation failed.

CycleOrHeight

Graph repeats a page or exceeds its height bound.

ChildBoundsMismatch

Parent routing bounds do not match the authenticated child.

IncompleteCoverage

Intersecting chunks did not cover the exact request.

ChunkLengthMismatch

Authenticated chunk bytes do not equal the indexed logical span.

Storage(ObjectStoreError)

Immutable-object backend rejected a read.

Decode(CanonicalDecodeError)

Canonical page failed decoding.

Work(WorkError)

Exact work exceeded or overflowed its budget.

Trait Implementations

impl Debug for BlobReadError

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

Formats the value using the given formatter.

impl Display for BlobReadError

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

Formats the value using the given formatter.

impl Error for BlobReadError

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.
