Why a credential or presentation is not well-formed, or cannot be mapped to or from the claims of a JWT.

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.

InvalidContext

The first @context is not the base context of the data model.

Fields

expected: &'static str

The base context required.

MissingType(&'static str)

type lacks the type the data model requires.

NoSubject

credentialSubject is an empty list.

InvalidValidity

The validity period ends before it starts.

Fields

from: &'static str

The property naming the start, issuanceDate or validFrom.

until: &'static str

The property naming the end, expirationDate or validUntil.

MultipleSubjects(usize)

A JWT carries one sub, so a credential with several subjects has no JWT form.

MissingClaim(&'static str)

The JWT claims set lacks the claim the profile requires.

InvalidClaim

A JWT claim has the wrong shape or an invalid value.

Fields

claim: &'static str

The claim.

reason: String

What is wrong with it.

ClaimMismatch

A JWT claim and the property it duplicates disagree.

Fields

claim: &'static str

The claim.

property: &'static str

The property of the credential or presentation.

UnsupportedMediaType

The enveloped credential or presentation is not in a form this crate reads.

Fields

kind: &'static str

credential or presentation.

media_type: String

The media type of the data: URL.

expected: &'static str

The media type this crate reads.

NotDataUrl(String)

An enveloped credential or presentation does not hold a data: URL.

Trait Implementations

impl Clone for CredentialError

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
