Enum bulletproofs::r1cs::R1CSError

pub enum R1CSError {
    InvalidGeneratorsLength,
    FormatError,
    VerificationError,
    MissingAssignment,
    GadgetError {
        description: String,
    },
}

Represents an error during the proving or verifying of a constraint system.

XXX: should this be separate from a ProofError?

Variants

InvalidGeneratorsLength

Occurs when there are insufficient generators for the proof.

FormatError

This error occurs when the proof encoding is malformed.

VerificationError

Occurs when verification of an R1CSProof fails.

MissingAssignment

Occurs when trying to use a missing variable assignment. Used by gadgets that build the constraint system to signal that a variable assignment is not provided when the prover needs it.

GadgetError

Occurs when a gadget receives an inconsistent input.

Fields of GadgetError

description: String

The description of the reasons for the error.

impl Eq for R1CSError

impl Fail for R1CSError

fn name(&self) -> Option<&str>

Returns the "name" of the error.

fn cause(&self) -> Option<&dyn Fail>

Returns a reference to the underlying cause of this failure, if it is an error that wraps other errors.

fn backtrace(&self) -> Option<&Backtrace>

Returns a reference to the Backtrace carried by this failure, if it carries one.

fn from(e: ProofError) -> R1CSError

Performs the conversion.

impl PartialEq<R1CSError> for R1CSError

fn eq(&self, other: &R1CSError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &R1CSError) -> bool

This method tests for !=.
