Struct curve25519_dalek::curve::PreComputedPoint

pub struct PreComputedPoint {
    pub y_plus_x: FieldElement,
    pub y_minus_x: FieldElement,
    pub xy2d: FieldElement,
}

A pre-computed point in the affine model for the curve, represented as (y+x, y-x, 2dxy). These precomputations accelerate addition and subtraction.

Fields

y_plus_x: FieldElement

y_minus_x: FieldElement

xy2d: FieldElement

Trait Implementations

impl Copy for PreComputedPoint

impl Clone for PreComputedPoint

fn clone(&self) -> PreComputedPoint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Identity for PreComputedPoint

fn identity() -> PreComputedPoint

Returns the identity element of the curve. Can be used as a constructor.

impl CTAssignable for PreComputedPoint

fn conditional_assign(&mut self, other: &PreComputedPoint, choice: u8)

If choice == 1u8, assign other to self. Otherwise, leave self unchanged. Executes in constant time.

impl<'a> Neg for &'a PreComputedPoint

type Output = PreComputedPoint

The resulting type after applying the - operator

fn neg(self) -> PreComputedPoint

The method for the unary - operator

impl Debug for PreComputedPoint

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
