How to add an Item to a Set in Rust ?

To add an item to a Set in Rust, you can use the standard library's HashSet data structure.

In this example,

use std::collections::HashSet;

fn main() {
    let mut my_set = HashSet::new();
    my_set.insert("item1");
    println!("{:?}", my_set);
}

{"item1"}

In this example,

use std::collections::HashSet;

fn main() {
    let mut number_set = HashSet::new();
    number_set.insert(123);
    println!("{:?}", number_set);
}

{123}
