Struct curve25519_dalek::curve::AffineNielsPoint

pub struct AffineNielsPoint {
    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, and were introduced by Niels Duif in the ed25519 paper "High-Speed High-Security Signatures".

Fields

y_plus_x: FieldElement

y_minus_x: FieldElement

xy2d: FieldElement

Trait Implementations

impl Copy for AffineNielsPoint

impl Clone for AffineNielsPoint

fn clone(&self) -> AffineNielsPoint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for AffineNielsPoint

impl PartialEq for AffineNielsPoint

fn eq(&self, __arg_0: &AffineNielsPoint) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &AffineNielsPoint) -> bool

This method tests for !=.

impl Identity for AffineNielsPoint

fn identity() -> AffineNielsPoint

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

impl CTAssignable for AffineNielsPoint

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

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

impl<'a> Neg for &'a AffineNielsPoint

type Output = AffineNielsPoint

The resulting type after applying the - operator

fn neg(self) -> AffineNielsPoint

The method for the unary - operator

impl Debug for AffineNielsPoint

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

Formats the value using the given formatter.
