Struct BinaryElem128 

pub struct BinaryElem128(/* private fields */);

Implementations

impl BinaryElem128

pub const fn from_value(val: u128) -> Self

impl BinaryElem128

pub fn mul_by_x(&self) -> Self

Multiply by x (field element 2) - very fast special case

In GF(2^128) with irreducible x^128 + x^7 + x^2 + x + 1, multiplying by x is just a left shift with conditional reduction. This is ~10x faster than general multiplication.

impl Default for BinaryElem128

fn default() -> BinaryElem128

Returns the “default value” for a type.

impl Distribution<BinaryElem128> for Standard

Available on crate feature rand only.

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> BinaryElem128

Generate a random value of T, using rng as the source of randomness.

fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T>

where R: Rng, Self: Sized,

Create an iterator that generates random values of T, using rng as the source of randomness.

fn map<F, S>(self, func: F) -> DistMap<Self, F, T, S>

where F: Fn(T) -> S, Self: Sized,

Create a distribution of values of ‘S’ by mapping the output of Self through the closure F

impl From<BinaryElem16> for BinaryElem128

fn from(elem: BinaryElem16) -> Self

Converts to this type from the input type.

impl From<BinaryElem32> for BinaryElem128

fn from(elem: BinaryElem32) -> Self

Converts to this type from the input type.

impl From<BinaryElem64> for BinaryElem128

fn from(elem: BinaryElem64) -> Self

Converts to this type from the input type.

impl From<u128> for BinaryElem128

fn from(val: u128) -> Self

impl PartialEq for BinaryElem128

fn eq(&self, other: &BinaryElem128) -> 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.
