pub struct StepRng { /* private fields */ }
Expand description
A simple implementation of RngCore
for testing purposes.
This generates an arithmetic sequence (i.e. adds a constant each step)
over a u64
number, using wrapping arithmetic. If the increment is 0
the generator yields a constant.
use rand::Rng;
use rand::rngs::mock::StepRng;
let mut my_rng = StepRng::new(2, 1);
let sample: [u64; 3] = my_rng.gen();
assert_eq!(sample, [2, 3, 4]);
