Struct PopulateError 

#[non_exhaustive]
pub struct PopulateError {
    pub failures: Vec<AssertionFailure>,
    pub total: usize,
}

Witness population failed because the circuit is not satisfied.

Evaluation runs to completion rather than stopping at the first bad assertion. So a caller sees every violation at once.

The retained list is capped at MAX_ASSERTION_FAILURES. Self::total counts every violation, capped or not. The two disagree exactly when the cap was reached.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

failures: Vec<AssertionFailure>

The failures that were retained, in the order evaluation found them.

total: usize

How many assertions failed in total, which may exceed failures.len().

Trait Implementations

impl Debug for PopulateError

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

Formats the value using the given formatter.

impl Display for PopulateError

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

Formats the value using the given formatter.

impl Error for PopulateError

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<PopulateError> for PopulateM4Error

fn from(source: PopulateError) -> Self

Converts to this type from the input type.
