Trait Implementations

impl Clone for G2Affine

fn clone(&self) -> G2Affine

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CurveAffine for G2Affine

type Engine = Bls12

type Scalar = Fr

type Base = Fq2

type Prepared = G2Prepared

type Projective = G2

type Uncompressed = G2Uncompressed

type Compressed = G2Compressed

type Pair = G1Affine

type PairingResult = Fq12

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 represents the point at infinity; the additive identity.

fn mul<S: Into<<Self::Scalar as PrimeField>::Repr>>(&self, by: S) -> G2

Performs scalar multiplication of this element with mixed addition.

fn negate(&mut self)

Negates this element.

fn prepare(&self) -> Self::Prepared

Prepares this element for pairing purposes.

fn pairing_with(&self, other: &Self::Pair) -> Self::PairingResult

Perform a pairing

fn into_projective(&self) -> G2

Converts this element into its affine representation.

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

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

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

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

fn from_xy_unchecked(x: Self::Base, y: Self::Base) -> Self

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

fn from_xy_checked(
    x: Self::Base,
    y: Self::Base
) -> Result<Self, GroupDecodingError>

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

fn a_coeff() -> Self::Base

returns A coefficient for a short Weierstrass form

fn b_coeff() -> Self::Base

returns B coefficient for a short Weierstrass form

fn into_compressed(&self) -> Self::Compressed

Converts this element into its compressed encoding, so long as it’s not the point at infinity.

fn into_uncompressed(&self) -> Self::Uncompressed

Converts this element into its uncompressed encoding, so long as it’s not the point at infinity.

impl Debug for G2Affine

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

Formats the value using the given formatter.

impl Display for G2Affine

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

Formats the value using the given formatter.

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<G2Affine> for G2Affine

fn eq(&self, other: &G2Affine) -> bool

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

fn ne(&self, other: &G2Affine) -> bool

This method tests for !=.
