【Rust】DefaultHasherで文字列から数値型へ

何度やっても同じ値になります。使い勝手は良さそう。

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

fn siphash13(s: String) {
    let mut siphash = DefaultHasher::new();
    s.hash(&mut siphash);
    println!("{:?}", siphash.finish());
    println!("{:?}", siphash);
}

fn main(){
    let mut t = "hello wolrd".to_string();
    siphash13(t);
}
