Struct Tab32Simple

pub struct Tab32Simple { /* private fields */ }

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

Usage:

use tab_hash::Tab32Simple;

fn main() {
    let keys = vec![0, 8, 15, 47, 11];
    let simple = Tab32Simple::new();
    for k in keys {
        println!("{}", simple.hash(k));
    }
}
