Struct rand::Isaac64Rng[][src]

pub struct Isaac64Rng { /* 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.

impl<'a> SeedableRng<&'a [u64]> for Isaac64Rng
[src]

Reseed an RNG with the given seed. Read more

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.
