# [−][src]Enum bulletproofs::ProofError

pub enum ProofError {
VerificationError,
FormatError,
WrongNumBlindingFactors,
InvalidBitsize,
InvalidAggregation,
InvalidGeneratorsLength,
ProvingError(MPCError),
}

Represents an error in proof creation, verification, or parsing.

## Variants

VerificationError

This error occurs when a proof failed to verify.

FormatError

This error occurs when the proof encoding is malformed.

WrongNumBlindingFactors

This error occurs during proving if the number of blinding factors does not match the number of values.

InvalidBitsize

This error occurs when attempting to create a proof with bitsize other than $$8$$, $$16$$, $$32$$, or $$64$$.

InvalidAggregation

This error occurs when attempting to create an aggregated proof with non-power-of-two aggregation size.

InvalidGeneratorsLength

This error occurs when there are insufficient generators for the proof.

ProvingError(MPCError)

This error results from an internal error during proving.

The single-party prover is implemented by performing multiparty computation with ourselves. However, because the MPC protocol is not exposed by the single-party API, we consider its errors to be internal errors.

## Blanket Implementations

### impl<T> Same<T> for T

#### type Output = T

Should always be Self

### impl<T> ToOwned for T where    T: Clone, [src]

#### type Owned = T

The resulting type after obtaining ownership.

### impl<T, U> TryFrom<U> for T where    U: Into<T>, [src]

#### type Error = !

The type returned in the event of a conversion error.

### impl<T, U> TryInto<U> for T where    U: TryFrom<T>, [src]

#### type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.
