Required Associated Types§

source

type Point

Required Methods§

source

fn create(basepoint: &Self::Point) -> Self

Generate a new precomputed basepoint table from the given basepoint.

source

fn basepoint(&self) -> Self::Point

Retrieve the original basepoint from this table.

source

fn mul_base(&self, scalar: &Scalar) -> Self::Point

Multiply a scalar by this precomputed basepoint table, in constant time.
