This trait represents an element of a field.

Required Methods

fn random<R: RngCore + ?Sized>(rng: &mut R) -> Self

Returns an element chosen uniformly at random using a user-provided RNG.

fn zero() -> Self

Returns the zero element of the field, the additive identity.

fn one() -> Self

Returns the one element of the field, the multiplicative identity.

fn is_zero(&self) -> bool

Returns true iff this element is zero.

fn square(&mut self)

Squares this element.

fn double(&mut self)

Doubles this element.

fn negate(&mut self)

Negates this element.

fn add_assign(&mut self, other: &Self)

Adds another element to this element.

fn sub_assign(&mut self, other: &Self)

Subtracts another element from this element.

fn mul_assign(&mut self, other: &Self)

Multiplies another element by this element.

fn inverse(&self) -> Option<Self>

Computes the multiplicative inverse of this element, if nonzero.

fn frobenius_map(&mut self, power: usize)

Exponentiates this element by a power of the base prime modulus via the Frobenius automorphism.

Provided Methods

fn pow<S: AsRef<[u64]>>(&self, exp: S) -> Self

Exponentiates this element by a number represented with u64 limbs, least significant digit first.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
