Variants

ThresholdEncryptionError(Error)

DealerNotInValidatorSet(EthereumAddress)

DKG validator set must contain the validator with the given address

UnknownDealer(EthereumAddress)

DKG received an unknown dealer. Dealer must be the part of the DKG validator set.

DuplicateDealer(EthereumAddress)

DKG received a PVSS transcript from a dealer that has already been dealt.

InvalidPvssTranscript(EthereumAddress)

DKG received an invalid transcript for which optimistic verification failed

InsufficientValidators(u32, u32)

Not enough validators to perform the DKG for a given number of shares

InvalidTranscriptAggregate

Transcript aggregate doesn’t match the received PVSS instances

ValidatorPublicKeyMismatch

The validator public key doesn’t match the one in the DKG

BincodeError(Error)

ArkSerializeError(SerializationError)

InvalidByteLength(usize, usize)

Invalid byte length

InvalidVariant(String)

Invalid variant

InvalidDkgParameters(u32, u32)

DKG parameters validation failed

InvalidShareIndex(u32)

Failed to access a share for a given share index

InvalidShareUpdate

Failed to verify a share update

InvalidDkgParametersForPrecomputedVariant(u32, u32)

Failed to produce a precomputed variant decryption share

DuplicatedShareIndex(u32)

DKG may not contain duplicated share indices

NoTranscriptsToAggregate

Creating a transcript aggregate requires at least one transcript

InvalidAggregateVerificationParameters(u32, u32)

The number of messages may not be greater than the number of validators

TooManyTranscripts(u32, u32)

Too many transcripts received by the DKG

DuplicateTranscript(EthereumAddress)

Received a duplicated transcript from a validator

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

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<Box<ErrorKind>> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<SerializationError> for Error

fn from(source: SerializationError) -> Self

Converts to this type from the input type.
