Enum PolyError 

pub enum PolyError {
    NonSquareMatrix {
        nrows: usize,
        ncols: usize,
    },
    ZeroDegree,
    InvalidOmega,
    InvalidBounds,
    PatternMismatch,
}

Error returned by polynomial-preconditioner construction.

Variants

NonSquareMatrix

The source matrix was not square.

Fields

nrows: usize

ncols: usize

ZeroDegree

degree was zero.

InvalidOmega

A Neumann omega was non-positive or non-finite.

InvalidBounds

The Chebyshev interval was not a usable 0 < lambda_min < lambda_max.

PatternMismatch

A refactorisation was attempted with a mismatched sparsity pattern.

Trait Implementations

impl Clone for PolyError

fn clone(&self) -> PolyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolyError

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

Formats the value using the given formatter.

impl Display for PolyError

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

Formats the value using the given formatter.

impl Error for PolyError

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 PartialEq for PolyError

fn eq(&self, other: &PolyError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
