Struct isaac::Rng

pub struct Rng { /* fields omitted */ }

A random number generator that uses ISAAC-64[1], the 64-bit variant of the ISAAC algorithm.

The ISAAC algorithm is generally accepted as suitable for cryptographic purposes, but this implementation has not be verified as such. Prefer a generator like OsRng that defers to the operating system for cases that need high security.

Methods

impl Rng

fn new_unseeded() -> Rng

Create a 64-bit ISAAC random number generator using the default fixed seed.

Trait Implementations

impl Clone for Rng

fn clone(&self) -> Rng

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Rng

impl Debug for Rng

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

Formats the value using the given formatter.

impl RandomGen for Rng

fn gen_u32(&mut self) -> u32

fn gen_u64(&mut self) -> u64

fn gen_f32(&mut self) -> f32

fn gen_f64(&mut self) -> f64

fn fill_bytes(&mut self, bs: &mut [u8])

fn gen<A>(&mut self) -> A where
    A: Random, 

impl<'a> Seedable<&'a [u64]> for Rng

fn reseed(&mut self, seed: &'a [u64])

fn from_seed(seed: &'a [u64]) -> Rng

Create an ISAAC random number generator with a seed. This can be any length, although the maximum number of elements used is 256 and any more will be silently ignored. A generator constructed with a given seed will generate the same sequence of values as all other generators constructed with that seed.

impl Random for Rng

fn random<G: ?Sized + RandomGen>(g: &mut G) -> Self
