Trait CurveConfig

pub trait CurveConfig:

    + 'static {
    type BaseField: Field;
    type ScalarField: PrimeField + Into<<Self::ScalarField as PrimeField>::BigInt>;

Elliptic curves can be represented via different “models” with varying efficiency properties. CurveConfig bundles together the types that are common to all models of the given curve, namely the BaseField over which the curve is defined, and the ScalarField defined by the appropriate prime-order subgroup of the curve.

Required Associated Constants

const COFACTOR: &'static [u64]

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

const COFACTOR_INV: Self::ScalarField

Required Associated Types

type BaseField: Field

Base field that the curve is defined over.

type ScalarField: PrimeField + Into<<Self::ScalarField as PrimeField>::BigInt>

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

Provided Methods

fn cofactor_is_one() -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
