Errors that can occur during polynomial operations

Variants

DivisionByZero

Division by zero polynomial

DivisionNotExact

Division did not yield exact result (non-zero remainder)

Fields

dividend: Expression

divisor: Expression

NotPolynomial

Not a valid polynomial (contains transcendental functions, negative powers, etc.)

Fields

expression: Expression

reason: String

WrongVariableCount

Polynomial has wrong number of variables for the operation

Fields

expected: usize

got: usize

operation: &'static str

VariableNotFound

Variable not found in polynomial

Fields

var: Symbol

DegreeComputationFailed

Degree computation failed (expression too complex or not polynomial)

Fields

expression: Expression

GcdComputationFailed

GCD computation failed

Fields

reason: String

FactorizationFailed

Factorization failed

Fields

reason: String

Fields

operation: &'static str

limit: usize

Trait Implementations

impl Clone for PolynomialError

fn clone(&self) -> PolynomialError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolynomialError

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

Formats the value using the given formatter.

impl Display for PolynomialError

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

Formats the value using the given formatter.

impl Error for PolynomialError

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 PolynomialError

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