Rust program to get the capacity of HashSet

Program/Source Code:

The source code to get the capacity of HashSet is given below. The given program is compiled and executed successfully.

// Rust program to get the capacity of HashSet

use std::collections::HashSet;
fn main() {
    let mut set: HashSet<_> = [10, 20, 30,40,50].iter().cloned().collect();
    
    println!("HashSet: {:?}", set);
    println!("Capacity of HashSet: {}",set.capacity());
}

Output:

HashSet: {30, 20, 40, 50, 10}
Capacity of HashSet: 7

Explanation:

Here we created a HashSet to store integer elements. Then we got the capacity of HashSet using the capacity() function and printed the result.
