Implementations

pub fn mul_assign_by_fp(&mut self, other: &P::Fp)

In-place multiply both coefficients c0 and c1 of self by an element from Fp.

Examples

let c0: Fp = Fp::rand(&mut test_rng());
let c1: Fp = Fp::rand(&mut test_rng());
let mut ext_element: Fp2 = Fp2::new(c0, c1);

let base_field_element: Fp = Fp::rand(&mut test_rng());
ext_element.mul_assign_by_fp(&base_field_element);

assert_eq!(ext_element.c0, c0 * base_field_element);
assert_eq!(ext_element.c1, c1 * base_field_element);

impl<P: Fp4Config> QuadExtField<Fp4ConfigWrapper<P>>

pub fn mul_by_034( &mut self, c0: &Fp2<<<P as Fp12Config>::Fp6Config as Fp6Config>::Fp2Config>, c3: &Fp2<<<P as Fp12Config>::Fp6Config as Fp6Config>::Fp2Config>, c4: &Fp2<<<P as Fp12Config>::Fp6Config as Fp6Config>::Fp2Config>, )

impl<P: QuadExtConfig> QuadExtField<P>

pub const fn new(c0: P::BaseField, c1: P::BaseField) -> Self

Create a new field element from coefficients c0 and c1, so that the result is of the form c0 + c1 * X.

Examples

let c0: Fp = Fp::rand(&mut test_rng());
let c1: Fp = Fp::rand(&mut test_rng());
// `Fp2` a degree-2 extension over `Fp`.
let c: Fp2 = Fp2::new(c0, c1);

pub fn conjugate_in_place(&mut self) -> &mut Self

This is only to be used when the element is known to be in the cyclotomic subgroup.

pub fn norm(&self) -> P::BaseField

Norm of QuadExtField over P::BaseField:Norm(a) = a * a.conjugate(). This simplifies to: Norm(a) = a.x^2 - P::NON_RESIDUE * a.y^2. This is alternatively expressed as Norm(a) = a^(1 + p).

Examples

let c: Fp2 = Fp2::rand(&mut test_rng());
let norm = c.norm();
// We now compute the norm using the `a * a.conjugate()` approach.
// A Frobenius map sends an element of `Fp2` to one of its p_th powers:
// `a.frobenius_map_in_place(1) -> a^p` and `a^p` is also `a`'s Galois conjugate.
let mut c_conjugate = c;
c_conjugate.frobenius_map_in_place(1);
let norm2 = c * c_conjugate;
// Computing the norm of an `Fp2` element should result in an element
// in BaseField `Fp`, i.e. `c1 == 0`
assert!(norm2.c1.is_zero());
assert_eq!(norm, norm2.c0);

pub fn mul_assign_by_basefield(&mut self, element: &P::BaseField)

In-place multiply both coefficients c0 & c1 of the quadratic extension field by an element from the base field.

const TRIVIAL_CHECK: bool

Whether the check method is trivial (i.e. always returns Ok(())). If this is true, the batch_check method will skip all checks and return Ok(()). This should be set to true for types where check is trivial, e.g. integers, field elements, etc. This is false by default. This is primarily an optimization to skip unnecessary checks in batch_check.

fn check(&self) -> Result<(), SerializationError>

Checks whether self is valid. If self is valid, returns Ok(()). Otherwise, returns an error describing the failure. This method is called by deserialize_with_mode if validate is Validate::Yes.

fn batch_check<'a>( batch: impl Iterator<Item = &'a Self> + Send, ) -> Result<(), SerializationError>

where Self: 'a,

Checks whether all items in batch are valid. If all items are valid, returns Ok(()). Otherwise, returns an error describing the first failure.

impl<P: QuadExtConfig> Zero for QuadExtField<P>

fn zero() -> Self

Returns the additive identity element of Self, 0.

fn is_zero(&self) -> bool

Returns true if self is equal to the additive identity.

fn set_zero(&mut self)

Sets self to the additive identity element of Self, 0.

impl<P: QuadExtConfig> Zeroize for QuadExtField<P>

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.

impl<P: QuadExtConfig> Eq for QuadExtField<P>
