Errors from sumcheck protocol verification.

Variants

RoundCountMismatch

The proof contains a different number of rounds than expected.

Fields

expected: usize

actual: usize

MissingSumcheckData

The proof is missing sumcheck data when rounds > 0.

Fields

expected_rounds: usize

InvalidPowWitness

Proof-of-work witness verification failed.

PowWitnessCountMismatch

The proof carries fewer PoW witnesses than sumcheck rounds.

Fields

expected: usize

actual: usize

WireSizeMismatch

HVZK sumcheck: a per-round wire payload had the wrong number of field elements. Each round must carry max(ℓ_zk - 1, 2) elements (after the linear coefficient is skipped per Lemma 6.4 / paper §6).

Fields

round: usize

expected: usize

actual: usize

EllZkMismatch

HVZK sumcheck: the proof’s claimed ell_zk (mask code message length) does not match the verifier’s expected value. Catches caller-side configuration mismatch between prover and verifier before the wire shape check.

Fields

expected: usize

actual: usize

Trait Implementations

impl Debug for SumcheckError

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

Formats the value using the given formatter.

impl Display for SumcheckError

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

Formats the value using the given formatter.

impl Eq for SumcheckError

impl Error for SumcheckError

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 PartialEq for SumcheckError

fn eq(&self, other: &SumcheckError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
