Methods

impl<E: JubjubEngine> Point<E, Unknown>

pub fn get_for_x(x: E::Fr, sign: bool, params: &E::Params) -> Option<Self>

#[must_use]pub fn mul_by_cofactor(&self, params: &E::Params) -> Point<E, PrimeOrder>

This guarantees the point is in the prime order subgroup

pub fn rand<R: RngCore>(rng: &mut R, params: &E::Params) -> Self

impl<E: JubjubEngine, Subgroup> Point<E, Subgroup>

pub fn from_edwards(e: &Point<E, Subgroup>, params: &E::Params) -> Self

Convert from an Edwards point

pub fn as_prime_order(&self, params: &E::Params) -> Option<Point<E, PrimeOrder>>

Attempts to cast this as a prime order element, failing if it's not in the prime order subgroup.

pub fn zero() -> Self

pub fn into_xy(&self) -> Option<(E::Fr, E::Fr)>

#[must_use]pub fn negate(&self) -> Self

#[must_use]pub fn double(&self, params: &E::Params) -> Self

#[must_use]pub fn add(&self, other: &Self, params: &E::Params) -> Self

#[must_use]pub fn mul<S: Into<<E::Fs as PrimeField>::Repr>>(
    &self,
    scalar: S,
    params: &E::Params
) -> Self

Trait Implementations

impl<E: JubjubEngine, Subgroup> Clone for Point<E, Subgroup>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: JubjubEngine> From<Point<E, PrimeOrder>> for Point<E, Unknown>

fn from(p: Point<E, PrimeOrder>) -> Point<E, Unknown>

Performs the conversion.

impl<E: JubjubEngine, Subgroup> PartialEq<Point<E, Subgroup>> for Point<E, Subgroup>

fn eq(&self, other: &Point<E, Subgroup>) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
