Enum Ic0Error 

pub enum Ic0Error {
    NonSquareMatrix {
        nrows: usize,
        ncols: usize,
    },
    MissingDiagonal {
        col: usize,

    PatternMismatch,
    NotPositiveDefinite {
        col: usize,

}

Error returned by IC(0) construction or refactorisation.

Variants

NonSquareMatrix

The source matrix was not square.

Fields

nrows: usize

ncols: usize

MissingDiagonal

Column col of the source matrix does not contain its diagonal entry.

Fields

col: usize

UnsortedRowIndices

Row indices in column col are not sorted ascending.

Fields

col: usize

PatternMismatch

A refactorisation was attempted with a matrix whose pattern does not match the symbolic factor.

NotPositiveDefinite

A non-positive pivot was encountered at column col — the matrix is not positive definite, or IC(0) has broken down on a non-H-matrix input.

Fields

col: usize

Trait Implementations

impl Clone for Ic0Error

fn clone(&self) -> Ic0Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ic0Error

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

Formats the value using the given formatter.

impl Display for Ic0Error

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

Formats the value using the given formatter.

impl Eq for Ic0Error

impl Error for Ic0Error

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 Ic0Error

fn eq(&self, other: &Ic0Error) -> 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.
