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

`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.
