Program/Source Code:

The source code to find the Union of two HashSets is given below. The given program is compiled and executed successfully.

// Rust program to find the 
// Union of two HashSets

use std::collections::HashSet;

fn main() {
    let set1: HashSet<_> = [10, 15, 30, 20,12].iter().cloned().collect();
    let set2: HashSet<_> = [10, 15, 20,40].iter().cloned().collect();

    println!("Union of set1 and set2:");
    for item in set1.union(&set2) {
        print!("{} ", item); 
    }
}

Output:

Union of set1 and set2:
15 12 10 30 20 40

Explanation:

Here we created two HashSets to store integer elements. Then we found the union of both sets using the union() method. After that, we printed the result.
