Errors propagated by methods in this module.

Variants

CircuitInLen

The caller of an arithmetic circuit provided the wrong number of inputs. This error may occur when evaluating a validity circuit or gadget.

CircuitIn(&'static str)

The caller of an arithmetic circuit provided malformed input.

Tuple Fields of CircuitIn

0: &'static str

CollectInLen

This error is returned by collect if the input slice is empty.

CollectGadgetInLenMismatch

This error is returned by collect if the two or more verifier shares have different gadget arities.

Fft(FftError)

Returned if an FFT operation propagates an error.

Tuple Fields of Fft

0: FftError

GadgetPolyInLen

When evaluating a gadget on polynomials, this error is returned if the input polynomials don’t all have the same length.

GadgetPolyOutLen

When evaluating a gadget on polynomials, this error is returned if the slice allocated for the output polynomial is too small.

Query(&'static str)

Calling query returned an error.

Tuple Fields of Query

0: &'static str

QueryRandInvalid

Returned by query if one of the elements of the query randomness vector is invalid. An element is invalid if using it to generate the verification message would result in a privacy violation.

If this error is returned, the caller may generate fresh randomness and retry.

Decide(&'static str)

Calling decide returned an error.

Tuple Fields of Decide

0: &'static str

ValidRandLen

The validity circuit was called with the wrong amount of randomness.

Valid(&'static str)

Encountered an error while evaluating a validity circuit.

Tuple Fields of Valid

0: &'static str

Field(FieldError)

Returned if a field operation encountered an error.

Tuple Fields of Field

0: FieldError

GetRandom(Error)

Failure when calling getrandom().

Tuple Fields of GetRandom

0: Error

Trait Implementations

impl Debug for PcpError

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

Formats the value using the given formatter.

impl Display for PcpError

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

Formats the value using the given formatter.

impl Error for PcpError

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

The lower-level source of this error, if any.

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

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

Returns a stack backtrace, if available, of where this error occurred.

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
