Enum StackingError 

pub enum StackingError {
    InvalidInput {
        message: String,
    },
    NumericalFailure {
        message: String,
        certificate: Option<StackingCertificate>,
        checkpoint: Option<StackingCheckpoint>,
    },
    DidNotConverge {
        max_iterations: usize,
        tolerance: f64,
        certificate: StackingCertificate,
        checkpoint: StackingCheckpoint,
    },
}

Typed stacking failure. In particular, exhaustion carries both its certificate evidence and an exact checkpoint rather than returning weights.

Trait Implementations

impl Clone for StackingError

fn clone(&self) -> StackingError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StackingError

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

Formats the value using the given formatter.

impl Display for StackingError

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

Formats the value using the given formatter.

impl Error for StackingError

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.
