Program/Source Code:

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

// Rust program to find the difference 
// between 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].iter().cloned().collect();

    println!("Difference (set1-set2):");
    for diff in set1.difference(&set2) {
        print!("{} ", diff); 
    }
}

Output:

Difference (set1-set2):
30 12

Explanation:

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