Enum VerificationError 

pub enum VerificationError {
    ConstantMismatch {
        value_index: u32,
        expected: u64,
        actual: u64,
    },
    Unsatisfied {
        constraint_index: usize,
        source: ConstraintViolation,
    },
}

Reason a value vector fails to satisfy a constraint system.

Variants

ConstantMismatch

A word declared as a constant opens to something else in the value vector.

Constraints read constants through the value vector. A vector that opens one to the wrong word therefore satisfies a different system.

Fields

value_index: u32

Position of the disagreeing word in the value vector.

expected: u64

The word the system declares at that position.

actual: u64

The word the value vector opens there.

Unsatisfied

A constraint does not hold on the value vector.

Fields

constraint_index: usize

Position of the constraint among those of its own kind, in storage order.

source: ConstraintViolation

The relation that failed, carrying the words that failed it.

Trait Implementations

impl Debug for VerificationError

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

Formats the value using the given formatter.

impl Display for VerificationError

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

Formats the value using the given formatter.

impl Error for VerificationError

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.

impl From<VerificationError> for VerificationM4Error

fn from(source: VerificationError) -> Self

Converts to this type from the input type.
