AffinePoint

nautilus_lighter::signing::curve

Struct AffinePoint 

Source 
pub struct AffinePoint {
    pub x: Fp5,
    pub u: Fp5,
}
Expand description

A point on the curve in affine (x, u) coordinates. Used as window entries in scalar multiplication; the affine form skips the Z and T denominators.

Fields§

§x: Fp5

Affine x coordinate.

§u: Fp5

Affine u coordinate (u = x / y).
