Struct BatchPopulateError 

#[non_exhaustive]
pub struct BatchPopulateError {
    pub instance: usize,
    pub source: PopulateError,
}

The failure of batch witness population, attributed to a single instance.

Serial batched evaluation reports the lowest-indexed failing instance. Parallel batched evaluation runs over independent stripes, and may report the first failing stripe observed.

The inner PopulateError is the error’s source, so the pair renders as one chain.

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.

instance: usize

The index of the reported failing instance.

source: PopulateError

The assertion failures recorded for that instance.

Trait Implementations

impl Debug for BatchPopulateError

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

Formats the value using the given formatter.

impl Display for BatchPopulateError

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

Formats the value using the given formatter.

impl Error for BatchPopulateError

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.
