Merge pull request #10 from zcash/curveaffine-coordinates 
Replace `(x, y)` tuple with `Coordinates` struct
 2021-04-19 22:27:22 +01:00
Jack Grigg
b016b972f8 Replace (x, y) tuple with Coordinates struct 
The previous `CurveAffine::get_xy` method returned the coordinates as
`CtOption<(C::Base, C::Base)>`. However, `ConditionallySelectable` is
not implemented for any tuple or array types, making it impossible to
use any of the useful `CtOption` methods like `and_then`. We replace it
with `CurveAffine::coordinates -> CtOption<Coordinates<Self>>` and
`impl ConditionallySelectable for Coordinates` to enable operating over
coordinates in constant time.

0a4db20d82 impl group::cofactor::CofactorGroup for Pallas and Vesta 
Prime-order groups can be treated as a group with a cofactor of 1,
allowing them to be used in cofactor-aware protocols like RedDSA.
