Struct tab_hash::Tab64Twisted

pub struct Tab64Twisted { /* fields omitted */ }

A universal hash function for 64-bit integers using twisted tabulation.

Usage:

use tab_hash::Tab64Twisted;

fn main() {
    let keys = vec![0, 8, 15, 47, 11];
    let twisted = Tab64Twisted::new();
    for k in keys {
        println!("{}", twisted.hash(k));
    }
}
