Struct AffinePoint 

pub struct AffinePoint {
    pub(crate) x: FieldElement,
    pub(crate) y: FieldElement,
}

This point representation is not a part of the API.

AffinePoint is mainly used as a convenience struct. XXX: Initially, I wanted to leave some of these in the library to help others learn. So if you are scrubbing the commit history. Hopefully they were helpful.

Represents an AffinePoint on the Twisted Edwards Curve with Equation y^2 - x^2 = 1 - (TWISTED_D) * x^2 * y^2

Fields

x: FieldElement

y: FieldElement

Implementations

impl AffinePoint

pub(crate) const IDENTITY: AffinePoint

Identity element

pub(crate) fn is_on_curve(&self) -> Choice

Checks if the AffinePoint is on the TwistedEdwards curve

pub(crate) fn negate(&self) -> AffinePoint

pub(crate) fn add(&self, other: &AffinePoint) -> AffinePoint

Adds an AffinePoint onto an AffinePoint

Trait Implementations

impl Clone for AffinePoint

fn clone(&self) -> AffinePoint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AffinePoint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AffinePoint

fn default() -> AffinePoint

Returns the “default value” for a type.

impl PartialEq for AffinePoint

fn eq(&self, other: &AffinePoint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for AffinePoint
