Enum snarkvm_r1cs::errors::SynthesisError

pub enum SynthesisError {

This is an error that could occur during circuit synthesis contexts, such as CRS generation, proving or verification.

Variants

AnyhowError(Error)

AssignmentMissing

During synthesis, we lacked knowledge of a variable assignment.

ConstraintFieldError(ConstraintFieldError)

Handles a failed conversion of objects into constraint field elements.

DivisionByZero

During synthesis, we divided by zero.

Unsatisfiable

During synthesis, we constructed an unsatisfiable constraint system.

PolynomialDegreeTooLarge

During synthesis, our polynomials ended up being too high of degree

UnexpectedIdentity

During proof generation, we encountered an identity in the CRS

IoError(Error)

During proof generation, we encountered an I/O error with the CRS

MalformedVerifyingKey(usize, usize)

During verification, our verifying key was malformed.

UnconstrainedVariable

During CRS generation, we observed an unconstrained auxiliary variable

Trait Implementations

impl Debug for SynthesisError

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

Formats the value using the given formatter.

impl Display for SynthesisError

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

Formats the value using the given formatter.

impl Error for SynthesisError

fn source(&self) -> Option<&(dyn Error + 'static)>

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
