Errors returned by polynomial operations.

Variants

InvalidModulus(u64)

The modulus must be at least 2.

DegreeOverflow

Input coefficients requested a degree that exceeds max_degree.

Fields

requested: usize

max_degree: usize

IncompatiblePolynomials

Polynomials are incompatible (different degree bounds or moduli).

ProductDegreeOverflow

Multiplication produced a degree higher than max_degree.

Fields

degree: usize

max_degree: usize

NttLengthMustBePowerOfTwo(usize)

NTT requires a non-zero power-of-two transform length.

NttLengthUnsupported

NTT length is not supported by the chosen modulus.

Fields

length: usize

modulus: u64

InvalidPrimitiveRoot

Provided primitive root cannot generate a valid root of unity for the transform length.

Fields

primitive_root: u64

length: usize

modulus: u64

DivisionByZeroPolynomial

Division by the zero polynomial is undefined.

NonInvertibleCoefficient

A required multiplicative inverse does not exist under the modulus.

Fields

coefficient: u64

modulus: u64

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.
