Struct EcPointFromXLibfunc

Source 
pub struct EcPointFromXLibfunc {}
Expand description

Libfunc for creating an EC point from its x coordinate. If there exists y such that (x, y) is on the curve, either (x, y) or (x, -y) (both constitute valid points on the curve) is returned. Otherwise, nothing is returned.
