rust-hash-ring
Consistent Hashing library for Rust
Usage
extern crate hash_ring;
use hash_ring::HashRing;
use hash_ring::NodeInfo;
fn main() {
let mut nodes: Vec<NodeInfo> = 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!(
"Key: '{}', Node: {}",
"hello",
hash_ring.get_node(("hello").to_string()).unwrap()
);
println!(
"Key: '{}', Node: {}",
"dude",
hash_ring.get_node(("dude").to_string()).unwrap()
);
println!(
"Key: '{}', Node: {}",
"martian",
hash_ring.get_node(("martian").to_string()).unwrap()
);
println!(
"Key: '{}', Node: {}",
"tardis",
hash_ring.get_node(("tardis").to_string()).unwrap()
);
hash_ring.remove_node(&NodeInfo {
host: "localhost",
port: 15329,
});
println!(
"Key: '{}', Node: {}",
"hello",
hash_ring.get_node(("hello").to_string()).unwrap()
);
hash_ring.add_node(&NodeInfo {
host: "localhost",
port: 15329,
});
println!(
"Key: '{}', Node: {}",
"hello",
hash_ring.get_node(("hello").to_string()).unwrap()
);
}
