Struct Polynomial 

pub struct Polynomial { /* private fields */ }

A degree-(t-1) polynomial over the scalar field used for VSS. Coefficients are little-endian: f(X) = sum coeff[k] * X^k.

Implementations

impl Polynomial

pub fn from_coefficients(coeff: Vec<Scalar>) -> Self

Build a polynomial from its coefficient vector. coeff[0] is the constant term (the committed secret for a VSS polynomial).

pub fn degree_plus_one(&self) -> usize

Number of coefficients — equal to the threshold T for a degree T-1 polynomial.

pub fn constant(&self) -> Scalar

The constant term f(0) — the committed secret.

pub fn coefficients(&self) -> &[Scalar]

Borrow the coefficient vector.

pub fn evaluate(&self, x: u32) -> Scalar

Evaluate f(x) at a party index using Horner’s rule.
