Elliptic curve

This trait contains all the low-level curve implementation logic: scalar, point arithmetics, encoding and etc.

Required Associated Constants

const CURVE_NAME: &'static str

Curve name

Required Associated Types

type Point: Additive + From<CurveGenerator> + Zero + Zeroize + OnCurve + SmallFactor + Copy + Eq + ConstantTimeEq + ConditionallySelectable + Default + CompressedEncoding<Bytes = Self::CompressedPointArray> + UncompressedEncoding<Bytes = Self::UncompressedPointArray> + Decode + Unpin + Sync + Send

Type that represents a curve point

type Scalar: Additive + Multiplicative<Self::Scalar, Output = Self::Scalar> + Multiplicative<CurveGenerator, Output = Self::Point> + Multiplicative<Self::Point, Output = Self::Point> + Invertible + Zero + One + Samplable + Zeroize + Copy + Eq + ConstantTimeEq + ConditionallySelectable + Default + IntegerEncoding<Bytes = Self::ScalarArray> + Unpin + Sync + Send

Type that represents a curve scalar

type CompressedPointArray: ByteArray

Byte array that fits the whole bytes representation of compressed point

type UncompressedPointArray: ByteArray

Byte array that fits the whole bytes representation of uncompressed point

type ScalarArray: ByteArray

Byte array that fits the whole bytes representation of a scalar

type CoordinateArray: ByteArray

Byte array that fits the whole bytes representation of a coordinate

If a curve doesn’t expose point coordinates, it may be [u8; 0]

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.
