Jump Consistent Hash
An implementation of the jump consistent hash algorithim as described in [A Fast, Minimal Memory, Consistent Hash Algorithim] (https://arxiv.org/pdf/1406.2294v1.pdf).
Example
extern crate jmphash;
use jmphash::jump_hash;
fn really_complicated_hash_function() -> u64 {
42
}
fn main() {
let num_buckets = 100;
// first use a hash function of your choice to create a u64 key
let key = really_complicated_hash_function();
// then one can use `jump_hash` to map the key to a bucket
let bucket = jump_hash(key, num_buckets);
}
