Struct dusk_jubjub::ExtendedNielsPoint

pub struct ExtendedNielsPoint { /* fields omitted */ }

This is a pre-processed version of an extended point (X, Y, Z, T1, T2) in the form (Y + X, Y - X, Z, T1 * T2 * 2d).

Implementations

impl ExtendedNielsPoint

pub const fn identity() -> Self

Constructs this point from the neutral element (0, 1).

pub fn multiply_bits(&self, by: &[u8; 32]) -> JubJubExtended

Multiplies this point by the specific little-endian bit pattern in the given byte array, ignoring the highest four bits.
