Math symbols related to modular arithmetics

Required Methods

fn checked_legendre(&self, n: Modulus) -> Option<i8>

Calculate Legendre Symbol (a|n), where a is self. Returns None only if n is not a prime.

Note that this function doesn’t perform a full primality check, since is costly. So if n is not a prime, the result can be not reasonable.

Panics

Only if n is not prime

fn checked_jacobi(&self, n: Modulus) -> Option<i8>

Calculate Jacobi Symbol (a|n), where a is self. Returns None if n is negative or even.

fn kronecker(&self, n: Modulus) -> i8

Calculate Kronecker Symbol (a|n), where a is self

Provided Methods

fn legendre(&self, n: Modulus) -> i8

Calculate Legendre Symbol (a|n), where a is self.

Note that this function doesn’t perform a full primality check, since is costly. So if n is not a prime, the result can be not reasonable.

Panics

Only if n is not prime

fn jacobi(&self, n: Modulus) -> i8

Calculate Jacobi Symbol (a|n), where a is self

Panics

if n is negative or even
