# peekmore
This crate introduces a multi-peekable iterator.
The iterator is similar to [core::iterator::Peekable](https://doc.rust-lang.org/core/iter/struct.Peekable.html).
The main difference is that Peekable only allows you to peek at the next element and no further.
This crate aims to take that limitation away.
The documentation and more extensive example usage can be found at [docs.rs/peekmore](https://docs.rs/peekmore/).
### Usage example:
```rust
use peekmore::PeekMore;
fn main() {
let range10 = 0..11;
let mut peekable = range10.peekmore();
// Peek at the first element
let peek_first = peekable.peek();
assert_eq!(*peek_first.unwrap(), 0);
let peek_first_redux = peekable.peek_nth(0);
assert_eq!(*peek_first_redux.unwrap(), 0);
// Peek at the 10th (index) element
let peek_tenth = peekable.peek_nth(10);
assert_eq!(*peek_tenth.unwrap(), 10);
// Consume the 10th element
let tenth = peekable.nth(10);
assert_eq!(tenth.unwrap(), 10);
// Show that there are no more elements
assert_eq!(peekable.peek(), None);
assert_eq!(peekable.next(), None);
}
```
