legacy curve, a copy of the normal curve to support legacy sponge params

Trait Implementations

impl Clone for LegacyVestaParameters

fn clone(&self) -> LegacyVestaParameters

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CurveConfig for LegacyVestaParameters

type BaseField = <VestaParameters as CurveConfig>::BaseField

Base field that the curve is defined over.

type ScalarField = <VestaParameters as CurveConfig>::ScalarField

Finite prime field corresponding to an appropriate prime-order subgroup of the curve group.

const COFACTOR: &'static [u64] = <VestaParameters as CurveConfig>::COFACTOR

The cofactor of this curve, represented as a sequence of little-endian limbs.

const COFACTOR_INV: Self::ScalarField = <VestaParameters as CurveConfig>::COFACTOR_INV

fn cofactor_is_one() -> bool

impl Default for LegacyVestaParameters

fn default() -> LegacyVestaParameters

Returns the “default value” for a type.

impl PartialEq<LegacyVestaParameters> for LegacyVestaParameters

fn eq(&self, other: &LegacyVestaParameters) -> 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 SWCurveConfig for LegacyVestaParameters

const COEFF_A: Self::BaseField = <VestaParameters as SWCurveConfig>::COEFF_A

Coefficient a of the curve equation.

const COEFF_B: Self::BaseField = <VestaParameters as SWCurveConfig>::COEFF_B

Coefficient b of the curve equation.

const GENERATOR: Affine<Self> = _

Generator of the prime-order subgroup.

fn mul_by_a(elem: Self::BaseField) -> Self::BaseField

Helper method for computing elem * Self::COEFF_A.

fn add_b(elem: Self::BaseField) -> Self::BaseField

Helper method for computing elem + Self::COEFF_B.

fn is_in_correct_subgroup_assuming_on_curve(item: &Affine<Self>) -> bool

Check if the provided curve point is in the prime-order subgroup.

fn clear_cofactor(item: &Affine<Self>) -> Affine<Self>

Performs cofactor clearing. The default method is simply to multiply by the cofactor. Some curves can implement a more efficient algorithm.

fn mul_projective(base: &Projective<Self>, scalar: &[u64]) -> Projective<Self>

Default implementation of group multiplication for projective coordinates

fn mul_affine(base: &Affine<Self>, scalar: &[u64]) -> Projective<Self>

Default implementation of group multiplication for affine coordinates.

fn msm( bases: &[Affine<Self>], scalars: &[Self::ScalarField] ) -> Result<Projective<Self>, usize>

Default implementation for multi scalar multiplication

fn serialize_with_mode<W>( item: &Affine<Self>, writer: W, compress: Compress ) -> Result<(), SerializationError>where W: Write,

If uncompressed, serializes both x and y coordinates as well as a bit for whether it is infinity. If compressed, serializes x coordinate with two bits to encode whether y is positive, negative, or infinity.

fn deserialize_with_mode<R>( reader: R, compress: Compress, validate: Validate ) -> Result<Affine<Self>, SerializationError>where R: Read,

If validate is Yes, calls check() to make sure the element is valid.

fn serialized_size(compress: Compress) -> usize
