How to create a Set of size N in Rust - Step by Step Examples

How to create a Set of size N in Rust ?

Answer

In Rust, sets are typically represented using the standard library's HashSet or BTreeSet. To create a set of size N with different types of items using arrays, you can use arrays with unique elements.

✐ Examples

1 Create Set of Size N with Strings

In this example,

We create an array named string_set with initial string elements.
We ensure that the array contains unique elements to represent a set.
The number of elements in the array determines the size of the set.

Rust Program

fn main() {
    let string_set = ["apple", "banana", "cherry"];
    let size = string_set.len();

    println!("Size of string_set: {}", size);
}

Output

Size of string_set: N

2 Create Set of Size N with Integers

In this example,

We create an array named int_set with initial integer elements.
We ensure that the array contains unique elements to represent a set.
The number of elements in the array determines the size of the set.

Rust Program

fn main() {
    let int_set = [1, 2, 3];
    let size = int_set.len();

    println!("Size of int_set: {}", size);
}

Output

Size of int_set: N
