How to Iterate Over a Set in Rust ?

Answer

To iterate over a set in Rust, you can use the `iter` method or a for loop.

✐ Examples

1 Iterate Over Set Using iter Method

In this example,

We define a set named `my_set` containing elements of a specific type.
We use the `iter` method to obtain an iterator over the set.
We then use a for loop to iterate over the iterator and access each element.
Finally, we execute the loop and process each item in the set.

Rust Program

fn main() {
    // Define set
    let my_set = [1, 2, 3, 4, 5].iter().collect::<std::collections::HashSet<_>>();

    // Iterate over set using iter method
    for item in my_set.iter() {
        println!("{:?}", item);
    }
}

Output

2 Iterate Over Set Using for Loop

In this example,

We define a set named `my_set` containing elements of a specific type.
We use a for loop to iterate over the set directly.
Finally, we execute the loop and process each item in the set.

Rust Program

fn main() {
    // Define set
    let my_set = [1, 2, 3, 4, 5].iter().collect::<std::collections::HashSet<_>>();

    // Iterate over set using for loop
    for item in &my_set {
        println!("{:?}", item);
    }
}
