Struct curve25519_dalek::curve::ProjectiveNielsPoint

pub struct ProjectiveNielsPoint { /* fields omitted */ }

A pre-computed point in the P³(𝔽ₚ) model for the curve, represented as (Y+X, Y-X, Z, 2dXY). These precomputations accelerate addition and subtraction, and were introduced by Niels Duif in the ed25519 paper "High-Speed High-Security Signatures".

Trait Implementations

impl Copy for ProjectiveNielsPoint

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 Identity for ProjectiveNielsPoint

fn identity() -> ProjectiveNielsPoint

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

impl CTAssignable for ProjectiveNielsPoint

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