Elliptic curve.

This trait is intended to be impl’d by a ZST which represents a concrete elliptic curve.

Other traits in this crate which are bounded by Curve are intended to be impl’d by these ZSTs, facilitating types which are generic over elliptic curves (e.g. SecretKey).

Required Associated Constants

const ORDER: Self::Uint

Order of this elliptic curve, i.e. number of elements in the scalar field.

Required Associated Types

type FieldBytesSize: ArrayLength<u8> + Add + Eq

Size of a serialized field element in bytes.

This is typically the same as Self::Uint::ByteSize but for curves with an unusual field modulus (e.g. P-224, P-521) it may be different.

type Uint: ArrayEncoding + AddMod<Output = Self::Uint> + Encoding + Integer + NegMod<Output = Self::Uint> + Random + RandomMod + SubMod<Output = Self::Uint> + Zeroize + FieldBytesEncoding<Self> + ShrAssign<usize>

Integer type used to represent field elements of this elliptic curve.

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.

Implementors
