Struct Tab32Twisted

pub struct Tab32Twisted { /* private fields */ }

A universal hash function for 32-bit integers using twisted tabulation.

Usage:

use tab_hash::Tab32Twisted;

fn main() {
    let keys = vec![0, 8, 15, 47, 11];
    let twisted = Tab32Twisted::new();
    for k in keys {
        println!("{}", twisted.hash(k));
    }
}
