Affine representation of an elliptic curve point guaranteed to be in the correct prime order subgroup.

Required Associated Types

type Scalar: PrimeField

type Curve: CofactorCurve<Affine = Self, Scalar = Self::Scalar>

Required Methods

fn identity() -> Self

Returns the additive identity.

fn generator() -> Self

Returns a fixed generator of unknown exponent.

fn is_identity(&self) -> Choice

Determines if this point represents the point at infinity; the additive identity.

fn to_curve(&self) -> Self::Curve

Converts this element to its curve representation.
