Rust program to iterate HashSet items using the 'for' loop

Rust | HashSet Example: Write a program to iterate HashSet items using the 'for' loop.
Submitted by Nidhi, on October 24, 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 "for" loop.

Program/Source Code:

The source code to iterate HashSet items using the "for" loop is given below. The given program is compiled and executed successfully.

// Rust program to iterate HashSet items 
// using "for" loop

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
    {
        print!("{} ",item);   
    }
}

Output:

HashSet: 
40 50 10 20 30

Explanation:

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