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 Copy for G2

impl CurveProjective for G2

type Engine = Bls12

type Scalar = Fr

type Base = Fq2

type Affine = G2Affine

fn random<R>(rng: &mut R) -> G2 where
    R: RngCore + ?Sized, 

Returns an element chosen uniformly at random using a user-provided RNG.

fn zero() -> G2

Returns the additive identity.

fn one() -> G2

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 [G2])

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: &G2)

Adds another element to this element.

fn add_assign_mixed(&mut self, other: &<G2 as CurveProjective>::Affine)

Adds an affine element to this element.

fn negate(&mut self)

Negates this element.

fn mul_assign<S>(&mut self, other: S) where
    S: Into<<<G2 as CurveProjective>::Scalar as PrimeField>::Repr>, 

Performs scalar multiplication of this element.

fn into_affine(&self) -> G2Affine

Converts this element into its affine representation.

fn recommended_wnaf_for_scalar(
    scalar: <<G2 as CurveProjective>::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 sub_assign(&mut self, other: &Self)

Subtracts another element from this element.

impl Debug for G2

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

Formats the value using the given formatter.

impl Display for G2

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

Formats the value using the given formatter.

impl Eq for G2

impl From<G2> for G2Affine

fn from(p: G2) -> G2Affine

Performs the conversion.

impl From<G2Affine> for G2

fn from(p: G2Affine) -> G2

Performs the conversion.

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 ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
