Scalar operator for this curve on finite finite $G_p$

Associated Constants

const SIZE: usize

Required methods

fn zero() -> Self

Get 0.

fn one() -> Self

Get 1.

fn invert(&self) -> Self

Invert a scalar.

fn reduce(&self) -> Self

Reduce a scalar by $p$ in $G_p$

Because scalar’s range in bytes always bigger than $p$, to get a vaild scalar on $G_p$, use reduce method.

fn neg(&self) -> Self

Negative a scalar.

fn add(&self, _rhs: &Self) -> Self

Add two scalar.

fn mul(&self, _rhs: &Self) -> Self

Multiply two scalar.

Provided methods

fn sub(&self, _rhs: &Self) -> Self where
    Self: Sized, 

Subtraction two scalar.
