Struct AffinePoint 

pub struct AffinePoint {
    pub x: BigUint,
    pub y: BigUint,
    pub infinity: bool,
}

An affine curve point, or the point at infinity.

The coordinates are ordinary residues in [0, p). The point at infinity is the group identity: P + ∞ = P and n·G = ∞.

Fields

x: BigUint

x-coordinate. Meaningful only when !infinity.

y: BigUint

y-coordinate. Meaningful only when !infinity.

infinity: bool

true when this represents the point at infinity (the group identity).

Implementations

impl AffinePoint

pub fn infinity() -> Self

The group identity (point at infinity).

pub fn new(x: BigUint, y: BigUint) -> Self

A finite affine point (x, y).

The caller is responsible for ensuring that (x, y) lies on the intended curve; use CurveParams::is_on_curve to validate.

pub fn is_infinity(&self) -> bool

Return true if this is the point at infinity.

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 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.
