Errors returned while validating Params.

Variants

InvalidPolynomial(PolynomialError)

Underlying polynomial validation failed.

ZeroModulusPolynomial

Modulus polynomial cannot be zero.

ConstantModulusPolynomial

Modulus polynomial must be non-constant.

ModulusPolynomialDegreeMismatch

degree(f) must match max_degree for a consistent fixed ring shape.

Fields

degree: usize

max_degree: usize

NonInvertibleModulusPolynomialLead

Leading coefficient of f(x) must be invertible in Z_q.

Fields

coefficient: u64

modulus: u64

NttLengthOverflow

Derived transform size overflowed for the selected degree bound.

Fields

max_degree: usize

NttLengthUnsupported

Derived NTT length is unsupported by the modulus (length must divide q - 1).

Fields

length: usize

modulus: u64

InvalidPrimitiveRoot

Primitive root does not induce a valid root of unity for the derived NTT length.

Fields

primitive_root: u64

length: usize

modulus: u64

Trait Implementations

impl Clone for ParamsError

fn clone(&self) -> ParamsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamsError

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

Formats the value using the given formatter.

impl Display for ParamsError

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

Formats the value using the given formatter.

impl Error for ParamsError

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 ParamsError

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