Usage

```rs extern crate hash_ring;

use hashring::HashRing; use hashring::NodeInfo;

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());

} ```
