Submitted by Nidhi, on October 26, 2021

Problem Solution:

In this program, we will create a HashSet to store integer items and then we will insert items using the insert () method and iterate HashSet items using the iter() method.

Program/Source Code:

The source code to iterate HashSet items using the iter() method is given below. The given program is compiled and executed successfully.

// Rust program to iterate HashSet items 
// using iter() method

use std::collections::HashSet;

fn main() {
    let mut set:HashSet<i32> = HashSet::new();
    
    set.insert(10);
    set.insert(20);
    set.insert(30);
    set.insert(40);
    set.insert(50);
 
    println!("HashSet: ");
    for item in set.iter()
    {
        print!("{} ",item);   
    }
}

Output:

HashSet: 
30 10 20 40 50

Explanation:

Here, we created a HashSet to store integer elements. Then we added items using the insert() method. After that, we iterate HashSet elements using the iter() method and printed them.
