[Rust] Iterating a map with its values.

use std::collections::HashMap;

fn main() {
    let mut hash = HashMap::new();

    hash.insert("one", "eins");
    hash.insert("two", "zwei");
    hash.insert("three", "drei");

    // Iterate the hash by value
    for v in hash.values() {
        println!("{}", *v);
    }
}
