Fail-closed canonical object decoding failures.

Variants

WrongDomain

Object belongs to another canonical domain.

UnsupportedVersion(u16)

Object format version is unsupported.

Truncated

Object ended before a declared field was complete.

ObjectTooLarge

Complete object exceeds the admitted allocation/work bound.

Fields

observed: u64

Observed bytes.

maximum: u64

Admitted maximum.

FieldTooLarge

One bounded field exceeds its admitted bytes.

Fields

observed: u32

Observed bytes or items.

maximum: u32

Admitted maximum.

LengthOverflow

Length arithmetic cannot be represented safely.

AllocationFailed

A bounded canonical encoding or decoding allocation failed.

TrailingBytes

Canonical object contains bytes after its final field.

UnknownTag

A field tag is not recognized by this version.

Fields

field: &'static str

Stable field description.

tag: u8

Unknown tag.

Invariant(String)

Decoded fields violate a semantic page invariant.

Trait Implementations

impl Clone for CanonicalDecodeError

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
