Enum VerificationError 

pub enum VerificationError {
    UnsupportedCryptosuite(String),
    MalformedProof(String),
    IssuerMismatch(String),
    SignatureInvalid,
    Other(String),
}

Reasons a ProofVerifier rejects a proof.

Mapping to crate::StandardCode for the wire: UnsupportedCryptosuite / MalformedProof / IssuerMismatch → crate::StandardCode::ProofInvalid; the consumer composes the trust-task-error response with that code per SPEC.md §7.2 item 7.

Variants

UnsupportedCryptosuite(String)

The proof’s cryptosuite is not implemented by this verifier.

MalformedProof(String)

The proof object is structurally invalid for the declared suite (missing required members, badly-encoded proofValue, etc.).

IssuerMismatch(String)

The verificationMethod does not resolve to material controlled by the document’s issuer — per SPEC.md §4.8 paragraph 1, the two MUST identify the same entity.

SignatureInvalid

The signature did not verify over the canonicalised document.

Other(String)

Any other failure surfaced by the underlying cryptosuite implementation.

Trait Implementations

impl Debug for VerificationError

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

Formats the value using the given formatter.

impl Display for VerificationError

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

Formats the value using the given formatter.

impl Error for VerificationError

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.
