Struct oberon::inner_types::elliptic_curve::point::NonIdentity
pub struct NonIdentity<P> { /* private fields */ }
Expand description
Non-identity point type.
This type ensures that its value is not the identity point, ala core::num::NonZero*
.
In the context of ECC, it’s useful for ensuring that certain arithmetic cannot result in the identity point.
