All errors that can arise in proof-cat.

Variants

Plonkish(Error)

An error propagated from plonkish-cat.

FieldCat(Error)

An error propagated from field-cat (field arithmetic or byte encoding).

WitnessSizeMismatch

Witness length does not match the wire count.

Fields

expected: usize

The number of wires expected.

actual: usize

The number of wire values provided.

UnsatisfiedConstraint

A constraint was not satisfied by the witness.

Fields

index: usize

The zero-based index of the failing constraint.

RoundCountMismatch

Sumcheck round count does not match the number of variables.

Fields

expected: usize

The expected number of rounds.

actual: usize

The actual number of rounds in the proof.

SumcheckFinalMismatch

Sumcheck final evaluation check failed.

MerkleVerificationFailed

Merkle opening proof does not match the committed root.

DimensionMismatch

Polynomial evaluation point has wrong dimension.

Fields

expected: usize

The expected number of variables.

actual: usize

The actual dimension of the point.

EmptyConstraintSet

Constraint set is empty; nothing to prove.

NotPowerOfTwo

A value is not a power of two where one was required.

Fields

value: usize

The non-power-of-two value.

LeafIndexOutOfBounds

Leaf index out of bounds for the Merkle tree.

Fields

index: usize

The requested index.

leaf_count: usize

The number of leaves.

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, f: &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<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.
