[−][src]Trait fawkes_crypto_pairing_ce::CurveProjective
Projective representation of an elliptic curve point guaranteed to be in the correct prime order subgroup.
Associated Types
type Engine: Engine<Fr = Self::Scalar>
type Scalar: PrimeField + SqrtField
type Base: SqrtField
type Affine: CurveAffine<Projective = Self, Scalar = Self::Scalar>
Required methods
fn zero() -> Self
Returns the additive identity.
fn one() -> Self
Returns a fixed generator of unknown exponent.
fn is_zero(&self) -> bool
Determines if this point is the point at infinity.
fn batch_normalization(v: &mut [Self])
Normalizes a slice of projective elements so that conversion to affine is cheap.
fn is_normalized(&self) -> bool
Checks if the point is already "normalized" so that cheap affine conversion is possible.
fn double(&mut self)
Doubles this element.
fn add_assign(&mut self, other: &Self)
Adds another element to this element.
fn add_assign_mixed(&mut self, other: &Self::Affine)
Adds an affine element to this element.
fn negate(&mut self)
Negates this element.
fn mul_assign<S: Into<<Self::Scalar as PrimeField>::Repr>>(&mut self, other: S)
Performs scalar multiplication of this element.
fn into_affine(&self) -> Self::Affine
Converts this element into its affine representation.
fn recommended_wnaf_for_scalar(
scalar: <Self::Scalar as PrimeField>::Repr
) -> usize
scalar: <Self::Scalar as PrimeField>::Repr
) -> usize
Recommends a wNAF window table size given a scalar. Always returns a number between 2 and 22, inclusive.
fn recommended_wnaf_for_num_scalars(num_scalars: usize) -> usize
Recommends a wNAF window size given the number of scalars you intend to multiply a base by. Always returns a number between 2 and 22, inclusive.
Provided methods
fn sub_assign(&mut self, other: &Self)
Subtracts another element from this element.
