Crate fasthash [−] [src]

A suite of non-cryptographic hash functions for Rust.

Example

use std::hash::{Hash, Hasher};

use fasthash::{metro, MetroHasher};

fn hash<T: Hash>(t: &T) -> u64 {
    let mut s = MetroHasher::new();
    t.hash(&mut s);
    s.finish()
}

let h = metro::hash64(b"hello world\xff");

assert_eq!(h, hash(&"hello world"));Run
