conshash 0.1.2

A library to do consistent hashing in Rust.

Crate conshash [] [src]

Example

extern crate conshash;

use std::hash::SipHasher;

#[derive(Clone, Debug)]
struct TestNode {
    host_name: &'static str,
    ip_address: &'static str,
    port: u32,
}

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

let mut hash_ring = Ring::new(5);

let test_node = TestNode{host_name: "Skynet", ip_address: "192.168.1.1", port: 42};
hash_ring.add_node(&test_node);
hash_ring.remove_node(&test_node);
hash_ring.add_node(&test_node);
let x = hash_ring.get_node(hash::<_, SipHasher>(&format!("{}{}", test_node.to_string(), 0.to_string())));
// x is the node in the form of an Option<T> where T: Clone + ToString + Debug
