Struct snapps_txn_reference_impl::primitives::Vesta

pub struct Vesta {}

A point on the ‘Vesta’ elliptic curve.

Points on this curve are defined by the equation y^2 = x^3 + a*x + b with the constants a = 0 and b = 5, where x and y are elements of the finite field Fq.

Points on the Vesta curve form a prime group of order 28948022309329048855892746252171976963363056481941647379679742748393362948097 under the standard elliptic curve addition operation.

Implementations

impl Vesta

pub fn one() -> Vesta

The elliptic curve point used as the generator for the group.

This is the constant point defined by x = 1, y = 11426906929455361843568202299992114520848200991084027513389447476559454104162

pub fn add(a: Vesta, b: Vesta) -> Vesta

The standard elliptic curve addition group operation on the Vesta curve.

pub fn scale(a: Vesta, s: Fp) -> Vesta

The standard elliptic curve scaling operation.

scale(a, s) = add(add(...add(a, a), ..., a), a), where add is applied s times.

Note that s is an element of the finite field of the same order as the group formed under add.

Trait Implementations

impl Clone for Vesta

fn clone(&self) -> Vesta

Returns a copy of the value.

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

Performs copy-assignment from source.
