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));
    }
}

Methods

impl Tab64Twisted

pub fn new() -> Self

Create a new twisted tabulation hash function with a random table.

pub fn with_table(table: [[u128; 256]; 8]) -> Self

Create a new twisted tabulation hash function with a given table.

pub fn get_table(&self) -> [[u128; 256]; 8]

Get the table used by this hash function.

pub fn hash(&self, x: u64) -> u64

Compute twisted tabulation hash value for a 64bit integer number.
