Jump Consistent Hash algorithm
Jump Consistent Hashing is a fast, minimal memory, consistent hash algorithm. In comparison to the algorithm of Karger et al., jump consistent hash requires no storage, is faster, and does a better job of evenly dividing the key space among the buckets and of evenly dividing the workload when the number of buckets changes.
Usage
use std::collections::hash_map::DefaultHasher;
use std::hash::{Hash, Hasher};
use jumpch::JumpHasher;
fn main () {
let mut hasher: JumpHasher<DefaultHasher> = JumpHasher::new(1000);
"test".hash(&mut hasher);
assert_eq!(hasher.finish(), 677)
}
use jumpch::hash;
fn main () {
assert_eq!(hash(123456, 1000), 176)
}
