-/// Creates a parallel iterator that produces an element exactly once.
-///
-/// This admits no parallelism on its own, but it could be chained to existing
-/// parallel iterators to extend their contents, or otherwise used for any code
-/// that deals with generic parallel iterators.
-///
-/// # Examples
-///
-/// ```
-/// use rayon::prelude::*;
-/// use rayon::iter::once;
-///
-/// let pi = (0..1234).into_par_iter()
-///     .chain(once(-1))
-///     .chain(1234..10_000);
-///
-/// assert_eq!(pi.clone().count(), 10_001);
-/// assert_eq!(pi.clone().filter(|&x| x < 0).count(), 1);
-/// assert_eq!(pi.position_any(|x| x < 0), Some(1234));
-/// ```
