Enum VerifyError 

#[non_exhaustive]
pub enum VerifyError {
    SignatureRequired,
    WrongKeyLength,
    WrongSignatureLength,
    Mismatch,
    PqcUnavailable,
    EnvelopeIncoherent,
}

Failure modes for verify_attestation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SignatureRequired

The policy-pinned class was RuntimeSignatureClass::None — a receipt that carries no signature cannot satisfy a class that requires one.

WrongKeyLength

The supplied public key was not the expected width for the class.

WrongSignatureLength

The supplied signature was not the expected width for the class.

Mismatch

The signature did not validate against the message under the key.

PqcUnavailable

An ML-DSA-65 verify was requested but the tier-2-pqc-receipts feature is not compiled in.

EnvelopeIncoherent

The receipt envelope is internally inconsistent — e.g. an MlDsa65/Hybrid algorithm with no PQC signature material.

Trait Implementations

impl Clone for VerifyError

fn clone(&self) -> VerifyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VerifyError

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

Formats the value using the given formatter.

impl Display for VerifyError

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

Formats the value using the given formatter.

impl Error for VerifyError

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.

impl PartialEq for VerifyError

fn eq(&self, other: &VerifyError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
