Enum SolveError 

pub enum SolveError {
    EmptySystem,
    NonLinear,
    NonSquare,
    Inconsistent,
    Underdetermined {
        rank: usize,
    },
    ResultNotInDomain,
    Matrix(MatrixError),
    Other(String),
}

Errors that can occur when solving equations.

Variants

EmptySystem

The system contains no equations.

NonLinear

The system is not linear in the requested variables.

NonSquare

The number of equations does not match the number of unknowns.

Inconsistent

The linear system has no solution.

Underdetermined

The system is underdetermined (infinitely many solutions).

Fields

rank: usize

Rank of the coefficient matrix.

ResultNotInDomain

The solution does not lie in the expected domain.

Matrix(MatrixError)

An internal matrix operation failed.

Other(String)

Other error with a description.

Trait Implementations

impl Clone for SolveError

fn clone(&self) -> SolveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SolveError

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

Formats the value using the given formatter.

impl Display for SolveError

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

Formats the value using the given formatter.

impl Eq for SolveError

impl Error for SolveError

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 From<MatrixError> for SolveError

fn from(e: MatrixError) -> SolveError

Converts to this type from the input type.

impl PartialEq for SolveError

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