Expand description

Non-zero scalar type.

This type ensures that its value is not zero, ala core::num::NonZero*. To do this, the generic S type must impl both Default and ConstantTimeEq, with the requirement that S::default() returns 0.

In the context of ECC, it’s useful for ensuring that scalar multiplication cannot result in the point at infinity.

Implementations

Generate a random NonZeroScalar.

Create a NonZeroScalar from a scalar.

Decode a NonZeroScalar from a big endian-serialized field element.

Create a NonZeroScalar from a C::UInt.
