Enum CredentialError 

pub enum CredentialError {
    MissingIssuer,
    MissingSubject,
    InvalidDid(String),
    Expired,
    InvalidProof,
    UnsupportedProofType(String),
}

Errors that can occur during credential operations.

Variants

MissingIssuer

The credential is missing an issuer

MissingSubject

The credential is missing a subject

InvalidDid(String)

The DID string is malformed

Expired

The credential has expired

InvalidProof

The proof is invalid or cannot be verified

UnsupportedProofType(String)

The proof type is not supported

Trait Implementations

impl Clone for CredentialError

fn clone(&self) -> CredentialError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CredentialError

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

Formats the value using the given formatter.

impl Display for CredentialError

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

Formats the value using the given formatter.

impl Error for CredentialError

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 CredentialError

fn eq(&self, other: &CredentialError) -> 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.
