[−][src]Struct dusk_bls12_381::G2Projective
This is an element of $\mathbb{G}_2$ represented in the projective coordinate space.
Methods
impl G2Projective
[src]
pub fn identity() -> G2Projective
[src]
Returns the identity of the group: the point at infinity.
pub fn generator() -> G2Projective
[src]
Returns a fixed generator of the group. See notes::design
for how this generator is chosen.
pub fn double(&self) -> G2Projective
[src]
Computes the doubling of this point.
pub fn add(&self, rhs: &G2Projective) -> G2Projective
[src]
Adds this point to another point.
pub fn add_mixed(&self, rhs: &G2Affine) -> G2Projective
[src]
Adds this point to another point in the affine model.
pub fn clear_cofactor(&self) -> G2Projective
[src]
Clears the cofactor, using Budroni-Pintore. This is equivalent to multiplying by $h_\textrm{eff} = 3(z^2 - 1) \cdot h_2$, where $h_2$ is the cofactor of $\mathbb{G}_2$ and $z$ is the parameter of BLS12-381.
The endomorphism is only actually used if the crate feature endo
is
enabled, and it is disabled by default to mitigate potential patent
issues.
pub fn batch_normalize(p: &[Self], q: &mut [G2Affine])
[src]
Converts a batch of G2Projective
elements into G2Affine
elements. This
function will panic if p.len() != q.len()
.
pub fn is_identity(&self) -> Choice
[src]
Returns true if this element is the identity (the point at infinity).
pub fn is_on_curve(&self) -> Choice
[src]
Returns true if this point is on the curve. This should always return true unless an "unchecked" API was used.
