Enum IlutpError 

pub enum IlutpError {
    NonSquareMatrix {
        nrows: usize,
        ncols: usize,
    },
    ZeroPivot {
        row: usize,
    },
    InvalidDropTol,
    InvalidPivotTol,
    InvalidFillControl,
}

Error returned by ILUTP construction or refactorisation.

Variants

NonSquareMatrix

The source matrix was not square.

Fields

nrows: usize

ncols: usize

ZeroPivot

Row row reduced to a zero pivot even after pivoting — the matrix is numerically singular for these parameters.

Fields

row: usize

InvalidDropTol

drop_tol was negative or NaN.

InvalidPivotTol

pivot_tol was outside [0, 1] or NaN.

InvalidFillControl

FillControl::Factor was non-positive or NaN.

Trait Implementations

impl Clone for IlutpError

fn clone(&self) -> IlutpError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IlutpError

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

Formats the value using the given formatter.

impl Display for IlutpError

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

Formats the value using the given formatter.

impl Eq for IlutpError

impl Error for IlutpError

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 IlutpError

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