The Random package provides support generating random numbers. The package provides random number generators you can use in your code, a dice roller and a trait for implementing your own random number generator.
If your application does not require a specific generator, use Rand.
Seed values can contain up to 128 bits of randomness in the form of two U64s.
A common non-cryptographically secure way to seed a generator is with
let rand = Rand let n = rand.next()
