Validation errors when checking a response against a request

Variants

InvalidProofRequest(String)

The request’s proof type does not match its fields.

RequestIdMismatch

The response id does not match the request id

VersionMismatch

The response version does not match the request version

ProofGenerationFailed(String)

The proof generation failed (response contains an error)

MissingCredential(String)

A required credential was not provided

UnexpectedCredential(String)

A credential was returned that was not requested.

DuplicateCredential(String)

A credential identifier was returned more than once.

ConstraintNotSatisfied

The provided credentials do not satisfy the request constraints

ConstraintTooDeep

The constraints expression exceeds the supported nesting depth

ConstraintTooLarge

The constraints expression exceeds the maximum allowed size/complexity

ExpiresAtMinMismatch(String, u64, u64)

The expires_at_min value in the response does not match the expected value from the request

SessionIdMismatch

Session ID doesn’t match between request and response

MissingSessionId

Session ID missing from a create-session response.

UnexpectedSessionId

Session ID present in a uniqueness response.

MissingSessionNullifier(String)

Session nullifier missing for credential in session proof

MissingNullifier(String)

Nullifier missing for credential in uniqueness proof

Trait Implementations

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Error for ValidationError

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 From<ValidationError> for AuthenticatorError

fn from(source: ValidationError) -> AuthenticatorError

Converts to this type from the input type.

impl PartialEq for ValidationError

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

impl Eq for ValidationError

impl StructuralPartialEq for ValidationError
