Remove an element from a vector in Rust

To remove an element from vec in rust you can simply use method remove(index_of_element) with index of item as parameter, once removed the indexes will be shifting toward the beginning (index 0).

See below example to remove an element from vec in Rust:

fn main() {

    let mut num = vec![10, 20, 30, 40, 50];

    // remove [2] (30)
    num.remove(2);

    println!("num[0]: {}", num[0]);
    println!("num[1]: {}", num[1]);
    println!("num[2]: {}", num[2]);
    println!("num[3]: {}", num[3]);

}

Output

num[0]: 10
num[1]: 20
num[2]: 40
num[3]: 50
