Usage

```rs extern crate hash_ring;

use hashring::hashring::HashRing;

[derive(Clone)]

struct NodeInfo { pub host: &'static str, pub port: u16 }

impl ToString for NodeInfo { fn to_string(&self) -> String { format!("{}:{}", self.host, self.port) } }

fn main() { let mut nodes: Vec = Vec::new(); nodes.push(NodeInfo{host: "localhost", port: 15324}); nodes.push(NodeInfo{host: "localhost", port: 15325}); nodes.push(NodeInfo{host: "localhost", port: 15326}); nodes.push(NodeInfo{host: "localhost", port: 15327}); nodes.push(NodeInfo{host: "localhost", port: 15328}); nodes.push(NodeInfo{host: "localhost", port: 15329});

let mut hash_ring: HashRing<NodeInfo> = HashRing::new(nodes, 10);

println!("{}", hash_ring.get_node(String::from_str("hello")).to_string());

println!("{}", hash_ring.get_node(String::from_str("dude")).to_string());

println!("{}", hash_ring.get_node(String::from_str("martian")).to_string());

println!("{}", hash_ring.get_node(String::from_str("tardis")).to_string());

hash_ring.remove_node(&NodeInfo{host: "localhost", port: 15329});

println!("{}", hash_ring.get_node(String::from_str("hello")).to_string());

hash_ring.add_node(&NodeInfo{host: "localhost", port: 15329});

println!("{}", hash_ring.get_node(String::from_str("hello")).to_string());

} ```
