Enum QuadraticVotingError 

#[non_exhaustive]
pub enum QuadraticVotingError {
    Variant {
        index: usize,
        error: VerificationError,
    },
    CreditRange(VerificationError),
    CreditEquivalence(VerificationError),
    OptionsLenMismatch {
        expected: usize,

    },
}

Errors that can occur when verifying QuadraticVotingBallots.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Variant

Error verifying a RangeProof for a vote for a particular option.

Fields

index: usize

Zero-based option index.

error: VerificationError

Error that occurred during range proof verification.

CreditRange(VerificationError)

Error verifying a RangeProof for credits.

CreditEquivalence(VerificationError)

Error verifying the proof of equivalence for credits.

OptionsLenMismatch

Mismatch between expected and actual number of options in the ballot.

Fields

expected: usize

Expected number of options.

actual: usize

Actual number of options.

Trait Implementations

impl Debug for QuadraticVotingError

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

Formats the value using the given formatter.

impl Display for QuadraticVotingError

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

Formats the value using the given formatter.

impl Error for QuadraticVotingError

Available on crate feature std only.

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.
