Unstable (rand)
: use rand from crates.io

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.

Fields

`cnt`	Unstable (`rand`) : use `rand` from crates.io
`rsl`	Unstable (`rand`) : use `rand` from crates.io
`mem`	Unstable (`rand`) : use `rand` from crates.io
`a`	Unstable (`rand`) : use `rand` from crates.io
`b`	Unstable (`rand`) : use `rand` from crates.io
`c`	Unstable (`rand`) : use `rand` from crates.io

Methods

`impl Isaac64Rng`

`fn new_unseeded() -> Isaac64Rng`

Unstable (rand)
: use rand from crates.io

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

`fn init(&mut self, use_rsl: bool)`

Unstable (rand)
: use rand from crates.io

Initialises self. If use_rsl is true, then use the current value of rsl as a seed, otherwise construct one algorithmically (not randomly).

`fn isaac64(&mut self)`

Unstable (rand)
: use rand from crates.io

Refills the output buffer (self.rsl)
