# rckad
Efficient and flexible S/Kademlia implementation.

```rust
use rckad::KadTree;

fn main() {
    let mut kad = KadTree::new(0, "0");
    kad.add(2, "b");
    kad.add(3, "c");
    kad.add(4, "e");

    assert_eq!(Some((&2, &"b", true)), kad.search(&2));
    assert_eq!(true, kad.contains(&2));

    kad.remove(&2);
    assert_eq!(false, kad.contains(&2));

    let mut kad = KadTree::with_k_bucket(0, "0".to_owned(), 2);

    for i in 1..(256 * 2 + 2) {
        kad.add(i, format!("{}", i));
    }

    assert_eq!(Some((&61, &"61".to_owned(), false)), kad.search(&131));
}
