Struct gridiron::fp_256::Monty

pub struct Monty { /* fields omitted */ }

This is the Montgomery form of the $classname. This is typically used for its fast implementation of Multiplication as the conversion to Montgomery form + multiplication is as fast as normal multiplication + reduction.

If you are doing more than 1 multiplication, it's clearly a win.

Methods

impl Monty

pub fn to_norm(self) -> Fp256

Bring the montgomery form back into the $classname.

Trait Implementations

impl Eq for Monty

impl PartialOrd<Monty> for Monty

fn partial_cmp(&self, other: &Monty) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use] fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use] fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use] fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Copy for Monty

impl PartialEq<Monty> for Monty

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Clone for Monty

fn clone(&self) -> Monty

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Ord for Monty

fn cmp(&self, other: &Monty) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl Add<Monty> for Monty

type Output = Monty

The resulting type after applying the + operator.

fn add(self, rhs: Monty) -> Monty

Performs the + operation.

impl Sub<Monty> for Monty

type Output = Monty

The resulting type after applying the - operator.

fn sub(self, rhs: Monty) -> Monty

Performs the - operation.

impl Mul<Monty> for Monty

type Output = Monty

The resulting type after applying the * operator.

fn mul(self, rhs: Monty) -> Monty

Performs the * operation.

impl Mul<u32> for Monty

Note that this reveals the u32, but nothing else. It's expected that the u32 is not secret. If it is, you can use Mul<$classname>

type Output = Monty

The resulting type after applying the * operator.

fn mul(self, rhs: u32) -> Monty

Performs the * operation.

impl Mul<Fp256> for Monty

type Output = Fp256

The resulting type after applying the * operator.

fn mul(self, rhs: Fp256) -> Fp256

Performs the * operation.

impl Mul<Monty> for Fp256

type Output = Fp256

The resulting type after applying the * operator.

fn mul(self, rhs: Monty) -> Fp256

Performs the * operation.

impl Neg for Monty

type Output = Monty

The resulting type after applying the - operator.

fn neg(self) -> Monty

Performs the unary - operation.

impl AddAssign<Monty> for Monty

fn add_assign(&mut self, other: Monty)

Performs the += operation.

impl SubAssign<Monty> for Monty

fn sub_assign(&mut self, other: Monty)

Performs the -= operation.

impl Zero for Monty

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.

impl One for Monty

fn one() -> Self

Returns the multiplicative identity element of Self, 1.

fn is_one(&self) -> bool

Returns true if self is equal to the multiplicative identity.

impl Pow<u32> for Monty

Note that this reveals the exponent, but nothing else. If you need constant time for the exponent, use Pow<$classname>.

type Output = Monty

The result after applying the operator.

fn pow(self, rhs: u32) -> Monty

Returns self to the power rhs.
