Struct bellperson::bls::G2Affine[][src]

pub struct G2Affine(_);
Expand description

This is an element of $\mathbb{G}_2$ represented in the affine coordinate space. It is ideal to keep elements in this representation to reduce memory usage and improve performance through the use of mixed curve model arithmetic.

Implementations

Returns the additive identity.

Returns a fixed generator of unknown exponent.

Determines if this point represents the point at infinity; the additive identity.

Serializes this element into compressed form.

Serializes this element into uncompressed form.

Attempts to deserialize an uncompressed element.

Attempts to deserialize an uncompressed element, not checking if the element is on the curve and not checking if it is in the correct subgroup.

This is dangerous to call unless you trust the bytes you are reading; otherwise, API invariants may be broken. Please consider using from_uncompressed() instead.

Returns true if this point is free of an $h$-torsion component, and so it exists within the $q$-order subgroup $\mathbb{G}_2$. This should always return true unless an “unchecked” API was used.

Returns true if this point is on the curve. This should always return true unless an “unchecked” API was used.

Returns the x coordinate.

Returns the y coordinate.
