Enum mpc_engine::Error

pub enum Error {
    Circuit(CircuitError),
    UnexpectedSubprotocolMessage(SubMessage),
    UnexpectedMessage(Message),
    BadCommitment([u8; 32], [u8; 32]),
    InvalidSerialization,
    CheckFailed(String),
    CurveError,
    AEADError,
    OtherError,
}

An error type.

We generally expect to definitely panic in two cases:

• Insufficient randomness was provided for a given operation
• A channel handle was prematurely dropped (this indicates a bug in the specification)

In other cases, the errors might be the result of a buggy protocol participant, or a detected attempt at cheating. These cases should be handled by the surrounding application in order to gracefully shut down or, if possible remove the cheater in a secure way, so these errors should be handled there.

Variants

Circuit(CircuitError)

An error during circuit processing

UnexpectedSubprotocolMessage(SubMessage)

A specific subprotocol message was expected but a different one was received.

UnexpectedMessage(Message)

A specific top-level message was expected but a different one was received

BadCommitment([u8; 32], [u8; 32])

Failed to open a commitment

InvalidSerialization

Failed to deserialize an authenticated bit

CheckFailed(String)

A malicious security check has failed

CurveError

Error from the curve implementation

AEADError

Error from the AEAD

OtherError

Miscellaneous error.
