Struct snapps_txn_reference_impl::primitives::Pallas

pub struct Pallas {}

A point on the ‘Pallas’ 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 Fp.

Points on the Pallas curve form a prime group of order 28948022309329048855892746252171976963363056481941560715954676764349967630337 under the standard elliptic curve addition operation.

Implementations

impl Pallas

pub fn one() -> Pallas

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

This is the constant point defined by x = 1, y = 12418654782883325593414442427049395787963493412651469444558597405572177144507

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

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

pub fn scale(a: Pallas, s: Fq) -> Pallas

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.

impl Pallas

pub fn compress(public_key: PublicKey) -> CompressedPublicKey

Compute the ‘compressed’ representation of a public key.

Trait Implementations

impl Clone for Pallas

fn clone(&self) -> Pallas

Returns a copy of the value.

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

Performs copy-assignment from source.
