impl IntMod for P256Coord

const MODULUS: Self::Repr = _

SelfRef<'a> should almost always be &'a Self. This is a way to include implementations of binary operations where both sides are &'a Self.

Creates a new IntMod from an instance of Repr.

fn from_le_bytes(bytes: &[u8]) -> Self

fn assert_unique(&self)

zkVM specific concept: the in-memory values of Self will normally be in their canonical unique form (e.g., less than modulus) but the zkVM circuit does not constrain it. In cases where uniqueness is essential for security, this function should be called to constrain uniqueness.

fn reduce(&mut self)
