Errors that can occur during identity operations

Variants

InvalidDid(String)

DID could not be parsed

NotFound(String)

Identity not found in the registry

AlreadyExists(String)

Identity already exists

NotActive(String)

Identity is not in the required state

PermissionDenied(String)

Operation not permitted

DelegationViolation(String)

Delegation scope violated

CredentialError(String)

Credential error

VerificationFailed(String)

Verification failed

TrustChainBroken

Trust chain is broken — an issuer in the chain is not Active, is not in the registry, has no key the credential could verify against, or its signature does not verify (CRITICAL #41).

Fields

issuer: String

DID of the issuer where the chain broke

reason: String

Human-readable reason

TrustChainCycle

A cycle was detected during trust chain traversal (CRITICAL #41). Contains the DID that was revisited.

Fields

issuer: String

DID that completed the cycle

TrustChainTooDeep

Trust chain exceeded the configured maximum traversal depth (CRITICAL #41). Acts as a DoS guard against arbitrarily long or maliciously crafted issuer chains.

Fields

max_depth: usize

Maximum depth allowed by the verifier configuration

NoTrustRoot

Trust chain terminated without reaching a recognized trust root (CRITICAL #41). The credential chain is internally consistent but does not anchor to any DID the verifier was configured to trust.

InvalidServiceEndpoint(String)

Invalid service endpoint URL (MEDIUM #128)

DuplicateCredential(String)

Credential already issued / replay attempt (MEDIUM #129)

UsernameTaken(String)

Username is already taken by another identity

UsernameInvalid(String)

Username does not meet validation requirements

WalletError(String)

Wallet provisioning or binding error

InvalidPublicKey(String)

Caller-supplied public key was malformed (wrong length, wrong curve, etc.). Used by BYOK registration paths.

CryptoError(String)

Cryptographic operation failed

SerializationError(String)

Serialization/deserialization error

Trait Implementations

impl Debug for IdentityError

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

Formats the value using the given formatter.

impl Display for IdentityError

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

Formats the value using the given formatter.

impl Error for IdentityError

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.
