A library to do consistent hashing in Rust.
Get the crate at conshash
```Rust extern crate conshash;
struct TestNode { hostname: &'static str, ipaddress: &'static str, port: u32, }
impl ToString for TestNode { fn tostring(&self) -> String { format!("{}{}", self.ipaddress.tostring(), self.port.tostring()) } }
let mut hash_ring = Ring::new(5);
let testnode = TestNode{hostname: "Skynet", ipaddress: "192.168.1.1", port: 42};
hashring.addnode(&testnode);
hashring.removenode(&testnode);
hashring.addnode(&testnode);
let x = hashring.getnode(hash(&format!("{}{}", testnode.tostring(), 0.to_string())));
// x is the node in the form of an Option
