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

y_plus_x: FieldElement51

xy2d: FieldElement51

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 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 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 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: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

Available on crate feature zeroize only.

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.

impl Copy for AffineNielsPoint

impl Eq for AffineNielsPoint

impl StructuralPartialEq for AffineNielsPoint
