Expand description
A CompletedPoint
is a point \(((X:Z), (Y:T))\) on the \(\mathbb
P^1 \times \mathbb P^1 \) model of the curve.
A point (x,y) in the affine model corresponds to \( ((x:1),(y:1))
\).
More details on the relationships between the different curve models can be found in the module-level documentation.

Implementations§
source§impl CompletedPoint
impl CompletedPoint
sourcepub fn as_projective(&self) -> ProjectivePoint
pub fn as_projective(&self) -> ProjectivePoint
Convert this point from the \( \mathbb P^1 \times \mathbb P^1 \) model to the \( \mathbb P^2 \) model.
This costs \(3 \mathrm M \).
sourcepub fn as_extended(&self) -> EdwardsPoint
pub fn as_extended(&self) -> EdwardsPoint
Convert this point from the \( \mathbb P^1 \times \mathbb P^1 \) model to the \( \mathbb P^3 \) model.
This costs \(4 \mathrm M \).
