Expand description

The interface for a generic field.

Required Associated Types§

Source

type BasePrimeField: PrimeField

Required Methods§

Source

fn from_base_prime_field(other: Self::BasePrimeField) -> Self

Constructs an element of Self from an element of the base prime field.

Source

fn characteristic<'a>() -> &'a [u64]

Returns the characteristic of the field.

Source

fn double(&self) -> Self

Returns self + self.

Source

fn double_in_place(&mut self)

Doubles self in place.

Source

fn square(&self) -> Self

Returns self * self.

Source

fn square_in_place(&mut self) -> &mut Self

Squares self in place.

Source

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

Computes the multiplicative inverse of self if self is nonzero.

Source

fn inverse_in_place(&mut self) -> Option<&mut Self>

Sets self to self’s inverse if it exists. Otherwise it is a no-op.

Source

fn frobenius_map(&mut self, power: usize)

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

Source

fn from_random_bytes_with_flags<F>(bytes: &[u8]) -> Option<(Self, F)>
where F: Flags,

Returns a field element with an extra sign bit used for group parsing if the set of bytes forms a valid field element, otherwise returns None. This function is primarily intended for sampling random field elements from a hash-function or RNG output.

Provided Methods§

Source

fn half() -> Self

Returns the constant 2^{-1}.

Source

fn sum_of_products<'a>(a: &'a [Self], b: &'a [Self]) -> Self

Source

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

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

Source

fn from_random_bytes(bytes: &[u8]) -> Option<Self>

Returns a field element if the set of bytes forms a valid field element, otherwise returns None. This function is primarily intended for sampling random field elements from a hash-function or RNG output.

Dyn Compatibility§

This trait is not dyn compatible.

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