How to Remove Specific Element from an Array in Rust ?

Answer

To remove a specific element from an array in Rust, you can create a new array excluding the element to be removed.

✐ Examples

1 Remove Element by creating a new array

In this example,

We create an array named `numbers` with elements including the one to be removed.
We use iteration or a filter condition to copy elements except the specific element to a new array.
Finally, we get a new array without the specific element.

Rust Program

fn main() {
    let numbers = [1, 2, 3, 4, 5];
    let element_to_remove = 3;
    let mut new_numbers = vec![];
    for &num in &numbers {
        if num != element_to_remove {
            new_numbers.push(num);
        }
    }
    println!("Array after removing {}: {:?}", element_to_remove, new_numbers);
}

Output

Array after removing 3: [1, 2, 4, 5]
