Struct nannou::rand::rngs::mock::StepRng [−][src]
pub struct StepRng { /* fields omitted */ }
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]);
Implementations
impl StepRng
[src]
pub fn new(initial: u64, increment: u64) -> StepRng
[src]
Create a StepRng
, yielding an arithmetic sequence starting with
initial
and incremented by increment
each time.
