Struct WireMod3 

pub struct WireMod3 { /* private fields */ }

Representation of a mod-3 wire.

We represent a mod-3 wire by 64 mod-3 elements. These elements are stored as follows: the least-significant bits of each element are stored in lsb and the most-significant bits of each element are stored in msb. This representation allows for efficient addition and multiplication as described here by the paper “Hardware Implementation of Finite Fields of Characteristic Three.” D. Page, N.P. Smart. CHES 2002.

Trait Implementations

impl Add for WireMod3

type Output = WireMod3

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl AddAssign for WireMod3

fn add_assign(&mut self, rhs: Self)

Performs the += operation.

impl Clone for WireMod3

fn clone(&self) -> WireMod3

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WireMod3

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

Formats the value using the given formatter.

impl Default for WireMod3

fn default() -> WireMod3

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for WireMod3

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl HasModulus for WireMod3

fn modulus(&self) -> u16

The modulus of the wire.

impl Mul<u16> for WireMod3

type Output = WireMod3

The resulting type after applying the * operator.

fn mul(self, rhs: u16) -> Self::Output

Performs the * operation.

impl MulAssign<u16> for WireMod3

impl Neg for WireMod3

type Output = WireMod3

The resulting type after applying the - operator.

fn neg(self) -> Self::Output

impl PartialEq for WireMod3

fn eq(&self, other: &WireMod3) -> bool

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Sub for WireMod3

type Output = WireMod3

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl SubAssign for WireMod3

fn sub_assign(&mut self, rhs: Self)

Performs the -= operation.

impl WireLabel for WireMod3

fn rand_delta<R: CryptoRng + RngCore>(rng: &mut R, q: u16) -> Self
