Struct Modular 

pub struct Modular { /* private fields */ }

A normalized modular residue paired with its positive modulus.

Implementations

impl Modular

pub fn new(value: i64, modulus: i64) -> Option<Modular>

Creates a normalized modular value.

Returns None when modulus <= 0.

pub const fn value(self) -> i64

Returns the normalized residue in 0..modulus.

pub const fn modulus(self) -> i64

Returns the positive modulus carried by this value.

pub fn add(self, other: Modular) -> Option<Modular>

Adds two modular values with the same modulus.

Returns None when the moduli differ.

pub fn sub(self, other: Modular) -> Option<Modular>

Subtracts two modular values with the same modulus.

Returns None when the moduli differ.

pub fn mul(self, other: Modular) -> Option<Modular>

Multiplies two modular values with the same modulus.

Returns None when the moduli differ.

pub fn pow(self, exponent: u64) -> Option<Modular>

Raises the modular value to exponent using modular exponentiation.

pub fn inverse(self) -> Option<Modular>

Computes the multiplicative inverse when one exists.

Trait Implementations

impl Clone for Modular

fn clone(&self) -> Modular

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Modular

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Modular

fn eq(&self, other: &Modular) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
