[][src]Struct rand::isaac::IsaacRng

pub struct IsaacRng { /* fields omitted */ }

A random number generator that uses the ISAAC algorithm[1].

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.

impl Debug for IsaacRng
[src]

impl<'a> SeedableRng<&'a [u32]> for IsaacRng
[src]

fn from_seed(seed: &'a [u32]) -> IsaacRng
[src]

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.
