Struct boulder::Cycle

pub struct Cycle<T>(_);

Recycle values from an iterator.

Since generators must produce an infinite sequence, this cycles the iterator to prevent it being exhausted.

Example:

use boulder::{Cycle, Generator};

let mut g = Cycle::new((1..3_i32).into_iter());
assert_eq!(g.generate(), 1);
assert_eq!(g.generate(), 2);
assert_eq!(g.generate(), 1);
