How to Rotate Items in a Vector in Rust - Step by Step Examples

How to Rotate Items in a Vector in Rust ?

Answer

To rotate items in a vector in Rust, you can use the `rotate_left` and `rotate_right` methods provided by the standard library.

✐ Examples

1 Rotate Items in Vector to the Left

fn main() {
    // Define a vector containing elements
    let mut vector = vec![1, 2, 3, 4, 5];

    // Specify the number of positions to rotate the items to the left
    let rotate_by = 2;

    // Rotate the items to the left by the specified number of positions
    vector.rotate_left(rotate_by);

    // Print the rotated vector
    println!("{:?}", vector);
}

[3, 4, 5, 1, 2]

2 Rotate Items in Vector to the Right

fn main() {
    // Define a vector containing elements
    let mut vector = vec![1, 2, 3, 4, 5];

    // Specify the number of positions to rotate the items to the right
    let rotate_by = 2;

    // Rotate the items to the right by the specified number of positions
    vector.rotate_right(rotate_by);

    // Print the rotated vector
    println!("{:?}", vector);
}
