How to check if Two Arrays are Equal in Rust

How to check if Two Arrays are Equal in Rust ?

Answer

To check if two arrays are equal in Rust, you can use the == operator for arrays with the same elements and manually compare elements for arrays with different elements.

✐ Examples

1 Arrays with Same Elements

In this example,

We create two arrays named arr1 and arr2 with the same elements.
We then use the == operator to check if the arrays are equal and store the result in the variable equal1.
The == operator checks if two arrays have the same elements in the same order.
Finally, we print the value of equal1 to the console.

Rust Program

fn main() {
    let arr1 = [1, 2, 3];
    let arr2 = [1, 2, 3];
    let equal1 = arr1 == arr2;
    println!("Arrays are equal: {:?}", equal1);
}

Output

Arrays are equal: true

2 Arrays with Different Elements

In this example,

We create two arrays named arr3 and arr4 with different elements.
We then manually compare each element of both arrays and store the result in the variable equal2.
If all elements are equal, equal2 is set to true; otherwise, it's set to false.
Finally, we print the value of equal2 to the console.

Rust Program

fn main() {
    let arr3 = [1, 2, 3];
    let arr4 = [3, 2, 1];
    let mut equal2 = true;
    for (a, b) in arr3.iter().zip(arr4.iter()) {
        if a != b {
            equal2 = false;
            break;
        }
    }
    println!("Arrays are equal: {:?}", equal2);
}

Output

Arrays are equal: false
