# peekaboo [docs](https://docs.rs/peekaboo/latest/peekaboo/) - [crates.io](https://crates.io/crates/peekaboo) Peekable iterator that allows to peek the next `N` elements without consuming them. It's `no_std` compatible by default. It also doesn't perform any allocations. ## Examples Basic usage: ```rust let xs = [1, 2, 3, 4, 5, 6, 7, 8, 9]; // create an iterator that allows us to peek at the next 4 element let mut iter = xs.iter().peekable_n::<4>(); // peek() lets us see into the future assert_eq!(iter.peek::<1>(), Some(&&1)); assert_eq!(iter.peek::<3>(), Some(&&3)); // the iterator will not advance until we call `next` assert_eq!(iter.next(), Some(&1)); assert_eq!(iter.next(), Some(&2)); ``` ## Use Run `cargo add peekaboo` (if using a Rust version over 1.62), or manually add ```toml peekaboo = "0.3.0" ``` to your `Cargo.toml`
