How to create a Set of integers in Rust ?

Answer

To create a set of integers in Rust, you can use the HashSet collection from the std::collections module.

✐ Examples

1 Create a Set of Integers using HashSet

In this example,

We import the HashSet struct from the std::collections module.
We create a HashSet object named int_set to store integers.
We use the insert() method to add integers to the set.

Rust Program

use std::collections::HashSet;

fn main() {
    let mut int_set = HashSet::new();
    int_set.insert(1);
    int_set.insert(2);
    int_set.insert(3);
    int_set.insert(4);
    int_set.insert(5);
    println!("Set of integers: {:?}", int_set);
}

Output

Set of integers: {1, 2, 3, 4, 5}
