Struct curve25519_dalek::backend::serial::curve_models::ProjectiveNielsPoint

pub struct ProjectiveNielsPoint {
    pub Y_plus_X: FieldElement51,
    pub Y_minus_X: FieldElement51,
    pub Z: FieldElement51,
    pub T2d: FieldElement51,
}

A pre-computed point on the \( \mathbb P^3 \) model for the curve, represented as \((Y+X, Y-X, Z, 2dXY)\) in “Niels coordinates”.

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

Trait Implementations

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

type Output = CompletedPoint

The resulting type after applying the + operator.

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

Performs the + operation.

impl Clone for ProjectiveNielsPoint

fn clone(&self) -> ProjectiveNielsPoint

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ConditionallySelectable for ProjectiveNielsPoint

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 ProjectiveNielsPoint

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

Formats the value using the given formatter.

impl Default for ProjectiveNielsPoint

fn default() -> ProjectiveNielsPoint

Returns the “default value” for a type.

impl Identity for ProjectiveNielsPoint

fn identity() -> ProjectiveNielsPoint

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

impl<'a> Neg for &'a ProjectiveNielsPoint

type Output = ProjectiveNielsPoint

The resulting type after applying the - operator.

fn neg(self) -> ProjectiveNielsPoint

Performs the unary - operation.

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

type Output = CompletedPoint

The resulting type after applying the - operator.

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

Performs the - operation.

impl Zeroize for ProjectiveNielsPoint

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 ProjectiveNielsPoint
