Error type for distributed key generation protocol operations.

This enum defines all possible errors that can occur during the execution of the DKG protocol, including message handling, cryptographic operations, and protocol state management.

Variants

InvalidMessage

Error while serializing or deserializing message data, or invalid message length

InvalidCommitmentHash

The commitment hash provided does not match the expected value

InvalidDLogProof

The discrete logarithm proof provided is invalid

InvalidPolynomialPoint

The polynomial point provided is invalid

InvalidKeyRefresh

The key refresh operation failed

InvalidQuorumChange

The quorum change operation failed

NotUniqueXiValues

The x_i values provided are not unique

BigFVecMismatch

The Big F vector does not match the expected value

FailedFelmanVerify

The Feldman verification failed

PublicKeyMismatch

The public key in the message does not match the party’s public key

BigSMismatch

The Big S value does not match the expected value

PPRFError(&'static str)

An error occurred in the PPRF (Pseudorandom Function) operation

MissingMessage

A required message is missing

SendMessage

Failed to send a message

AbortProtocol(usize)

A party has decided to abort the protocol

Trait Implementations

impl Debug for KeygenError

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

Formats the value using the given formatter.

impl Display for KeygenError

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

Formats the value using the given formatter.

impl Error for KeygenError

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<Error> for KeygenError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<MessageSendError> for KeygenError

fn from(_err: MessageSendError) -> Self

Converts to this type from the input type.
