Trait Implementations

impl VartimePrecomputedMultiscalarMul for VartimePrecomputedStraus

type Point = EdwardsPoint

The type of point to be multiplied, e.g., RistrettoPoint.

fn new<I>(static_points: I) -> Self

where I: IntoIterator, I::Item: Borrow<EdwardsPoint>,

Given the static points \( B_i \), perform precomputation and return the precomputation data.

fn optional_mixed_multiscalar_mul<I, J, K>( &self, static_scalars: I, dynamic_scalars: J, dynamic_points: K, ) -> Option<EdwardsPoint>

where I: IntoIterator, I::Item: Borrow<Scalar>, J: IntoIterator, J::Item: Borrow<Scalar>, K: IntoIterator<Item = Option<EdwardsPoint>>,

Given static_scalars, an iterator of public scalars \(b_i\), dynamic_scalars, an iterator of public scalars \(a_i\), and dynamic_points, an iterator of points \(A_i\), compute $$ Q = a_1 A_1 + \cdots + a_n A_n + b_1 B_1 + \cdots + b_m B_m, $$ where the \(B_j\) are the points that were supplied to new.

fn vartime_multiscalar_mul<I>(&self, static_scalars: I) -> Self::Point

where I: IntoIterator, I::Item: Borrow<Scalar>,

Given static_scalars, an iterator of public scalars \(b_i\), compute $$ Q = b_1 B_1 + \cdots + b_m B_m, $$ where the \(B_j\) are the points that were supplied to new.

fn vartime_mixed_multiscalar_mul<I, J, K>( &self, static_scalars: I, dynamic_scalars: J, dynamic_points: K, ) -> Self::Point

where I: IntoIterator, I::Item: Borrow<Scalar>, J: IntoIterator, J::Item: Borrow<Scalar>, K: IntoIterator, K::Item: Borrow<Self::Point>,

Given static_scalars, an iterator of public scalars \(b_i\), dynamic_scalars, an iterator of public scalars \(a_i\), and dynamic_points, an iterator of points \(A_i\), compute $$ Q = a_1 A_1 + \cdots + a_n A_n + b_1 B_1 + \cdots + b_m B_m, $$ where the \(B_j\) are the points that were supplied to new.
