How to Join Vectors in Rust ?

Answer

In Rust, you can join vectors using the `extend()` method or the `append()` method.

✐ Examples

1 Join Vectors using extend() method

In this example,

We define two vectors, vec1 and vec2, with different elements.
We use the extend() method to concatenate the elements of vec2 into vec1.

Rust Program

fn main() {
    let mut vec1 = vec![1, 2, 3];
    let vec2 = vec![4, 5, 6];

    // Join vectors using extend() method
    vec1.extend(vec2);

    // Print the combined vector
    println!("{:?}", vec1);
}

Output

[1, 2, 3, 4, 5, 6]

2 Join Vectors using append() method

In this example,

We define two vectors, vec1 and vec2, with different elements.
We use the append() method to append elements of vec2 to vec1.

Rust Program

fn main() {
    let mut vec1 = vec![1, 2, 3];
    let vec2 = vec![4, 5, 6];

    // Join vectors using append() method
    vec1.append(&mut vec2.clone());

    // Print the combined vector
    println!("{:?}", vec1);
}

Output

[1, 2, 3, 4, 5, 6]
