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.

PostcardDeserializeError(Error)

Deserialization error originating from postcard.

AlloySignatureError(SignatureError)

Signature parsing or verification error.

RequestError(RequestError)

Malformed proof request error.

SignatureVerificationError

Signature verification error.

Fields

recovered_addr: Address

Address recovered when trying to verify the ECDSA signature.

expected_addr: Address

Address expected from decoding the ProofRequest.

SignatureNonCanonicalError

Signature is non-canonical.

RequirementsEvaluationError

Predicate evaluation failure from ProofRequest [Requirements]

FulfillmentDataError(FulfillmentDataError)

Fulfillment data malformed or invalid

PredicateError(PredicateError)

Predicate error due to malformed data

UnknownFulfillmentDataType(FulfillmentData)

Fulfillment data type is not recognized.

UnknownPredicateType(Predicate)

Predicate type is not recognized.

InvalidFulfillmentPredicateCombination

Invalid combination of fulfillment type and predicate type

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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
