Struct sss_rs::geometry::galois_polynomial::GaloisPolynomial

pub struct GaloisPolynomial { /* fields omitted */ }

Methods

impl GaloisPolynomial

pub fn new() -> GaloisPolynomial

Constructs a polynomail with no coefficients

pub fn from_slice(coeffs: &[u8]) -> GaloisPolynomial

Copies the values from the coeffs slice into a vec as the coefficients of the polynomial The coefficients go from left to right, where x^0 at coeffs[0]

pub fn with_vec(coeffs: Vec<u8>) -> GaloisPolynomial

Constructs a polynomial with the coefficients in the vec The coefficients go from left to right, where x^0 at coeffs[0]

pub fn from_points(points: &[(u8, u8)]) -> GaloisPolynomial

Reconstructs a polynomial from the given points

pub fn get_y_intercept_from_points(points: &[(u8, u8)]) -> u8

Calculates the y intercept of the polynomial formed by the given points This is more efficient than completely reconstructing the polynomial and then calling $get_y_val if you do not plan to use the reconstructed polynomial after getting the y intercept.

pub fn set_coeff(&mut self, co: Coeff, index: usize)

Sets the coefficient at the given index to the given co

pub fn get_coeff(&self, index: usize) -> Coeff

Returns a copy of the coefficient at the specified index

pub fn scale(self, co: Coeff) -> Self

Scales the polynomial by multiplying by the co

pub fn scale_divide(self, co: Coeff) -> Self

Scales the polynomial by dividing by the co

pub fn mult(self, rhs: Self) -> Self

Multiplies two polynomial together

pub fn add(self, rhs: Self) -> Self

Adds two polynomials together

pub fn get_y_value(&self, x_val: u8) -> u8

Calculates the y-value given an x-value
