Struct rand::read::ReadRng [] [src]

pub struct ReadRng<R> { /* fields omitted */ }

An RNG that reads random bytes straight from a Read. This will work best with an infinite reader, but this is not required.

Panics

It will panic if it there is insufficient data to fulfill a request.

Example

use rand::{read, Rng};

let data = vec![1, 2, 3, 4, 5, 6, 7, 8];
let mut rng = read::ReadRng::new(&data[..]);
println!("{:x}", rng.gen::<u32>());
