Error encountered during GKR protocol verification.

Variants

MalformedProof

The proof is malformed.

InvalidMask

Mask has an invalid number of columns.

Fields

instance: usize

instance_layer: LayerIndex

Layer of the instance (but not necessarily the batch).

NumInstancesMismatch

There is a mismatch between the number of instances in the proof and the number of instances passed for verification.

Fields

given: usize

proof: usize

InvalidSumcheck

There was an error with one of the sumcheck proofs.

Fields

layer: LayerIndex

source: SumcheckError<F>

CircuitCheckFailure

The circuit polynomial the verifier evaluated doesn’t match claim from sumcheck.

Fields

claim: F

output: F

layer: LayerIndex

Trait Implementations

impl<F: Debug> Debug for GkrError<F>

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

Formats the value using the given formatter.

impl<F> Display for GkrError<F>

where SumcheckError<F>: Display, F: Display,

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

Formats the value using the given formatter.

impl<F> Error for GkrError<F>

where SumcheckError<F>: Error + 'static, Self: Debug + Display,

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
