Trait Implementations

impl Clone for G2

fn clone(&self) -> G2

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CurveProjective for G2

type Engine = Bls12

type Scalar = Fr

type Base = Fq2

type Affine = G2Affine

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 is_normalized(&self) -> bool

Checks if the point is already “normalized” so that cheap affine conversion is possible.

fn batch_normalization(v: &mut [Self])

Normalizes a slice of projective elements so that conversion to affine is cheap.

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) -> G2Affine

Converts this element into its affine representation.

fn recommended_wnaf_for_scalar(
    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.

fn as_xyz(&self) -> (&Self::Base, &Self::Base, &Self::Base)

Returns references to underlying X, Y and Z coordinates. Users should check for infinity outside of this call

fn into_xyz_unchecked(self) -> (Self::Base, Self::Base, Self::Base)

Returns underlying X, Y and Z coordinates. Users should check for infinity outside of this call

fn from_xyz_unchecked(x: Self::Base, y: Self::Base, z: Self::Base) -> Self

Creates a point from raw X, Y and Z coordinates. Point of infinity is encoded as (0,1,0) by default. On-curve check is NOT performed

fn from_xyz_checked(
    _x: Self::Base,
    _y: Self::Base,
    _z: Self::Base
) -> Result<Self, GroupDecodingError>

Creates a point from raw X, Y and Z coordinates. Point of infinity is encoded as (0,1,0) by default. On-curve check is performed

fn sub_assign(&mut self, other: &Self)

Subtracts another element from this element.

impl Debug for G2

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

Formats the value using the given formatter.

impl Display for G2

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

Formats the value using the given formatter.

impl From<G2> for G2Affine

fn from(p: G2) -> G2Affine

Converts to this type from the input type.

impl From<G2Affine> for G2

fn from(p: G2Affine) -> G2

Converts to this type from the input type.

impl PartialEq<G2> for G2

fn eq(&self, other: &G2) -> bool

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

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

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

impl Rand for G2

fn rand<R: Rng>(rng: &mut R) -> Self

Generates a random instance of this type using the specified source of randomness.

impl Copy for G2

impl Eq for G2

impl StructuralEq for G2
