Struct Point 

pub struct Point(/* private fields */);

A point on the curve, in extended twisted Edwards coordinates.

The public face of Ext on the portable field. The signing and verification paths do not go through it: they run on whichever field the CPU selects, and this is for callers who want the group itself.

Implementations

impl Point

pub const IDENTITY: Point

The neutral element (0, 1).

pub fn add(&self, other: &Point) -> Point

The complete add-2008-hwcd-3 group law for a = -1.
