Struct curve25519_dalek::backend::serial::curve_models::AffineNielsPoint

pub struct AffineNielsPoint {
    pub y_plus_x: FieldElement51,
    pub y_minus_x: FieldElement51,
    pub xy2d: FieldElement51,
}

A pre-computed point in the affine model for the curve, represented as \((y+x, y-x, 2dxy)\) in "Niels coordinates".

More details on the relationships between the different curve models can be found in the module-level documentation.

Fields

Trait Implementations

impl<'a, 'b> Add<&'b AffineNielsPoint> for &'a EdwardsPoint

type Output = CompletedPoint

The resulting type after applying the + operator.

fn add(self, other: &'b AffineNielsPoint) -> CompletedPoint

Performs the + operation.

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 ConditionallySelectable for AffineNielsPoint

fn conditional_select(a: &Self, b: &Self, choice: Choice) -> Self

Select a or b according to choice.

fn conditional_assign(&mut self, other: &Self, choice: Choice)

Conditionally assign other to self, according to choice.

fn conditional_swap(a: &mut Self, b: &mut Self, choice: Choice)

Conditionally swap self and other if choice == 1; otherwise, reassign both unto themselves.

impl Copy for AffineNielsPoint

impl Debug for AffineNielsPoint

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

Formats the value using the given formatter.

impl Default for AffineNielsPoint

fn default() -> AffineNielsPoint

Returns the "default value" for a type.

impl Eq for AffineNielsPoint

fn assert_receiver_is_total_eq(&self)

impl Identity for AffineNielsPoint

fn identity() -> AffineNielsPoint

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

impl<'a> Neg for &'a AffineNielsPoint

type Output = AffineNielsPoint

The resulting type after applying the - operator.

fn neg(self) -> AffineNielsPoint

Performs the unary - operation.

impl PartialEq<AffineNielsPoint> for AffineNielsPoint

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

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

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

This method tests for !=.

impl StructuralEq for AffineNielsPoint

impl StructuralPartialEq for AffineNielsPoint

impl<'a, 'b> Sub<&'b AffineNielsPoint> for &'a EdwardsPoint

type Output = CompletedPoint

The resulting type after applying the - operator.

fn sub(self, other: &'b AffineNielsPoint) -> CompletedPoint

Performs the - operation.

impl Zeroize for AffineNielsPoint

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not "optimized away" by the compiler.
