How to Join Arrays in Rust ?

Answer

To join arrays in Rust, you can use the append method for vectors or the extend method.

✐ Examples

1 Joining Arrays using append Method

In this example,

We create two vectors, vec1 and vec2.
We then use the append method of vec1 to append elements of vec2 to the end of vec1.
The result is a new vector result containing elements from both vec1 and vec2.

Rust Program

fn main() {
    let mut vec1 = vec![1, 2, 3];
    let vec2 = vec![4, 5, 6];
    vec1.append(&amp;mut vec2);
    println!("Joined Vector: {:?}", vec1);
}

Output

Joined Vector: [1, 2, 3, 4, 5, 6]

2 Joining Arrays using extend Method

In this example,

We create two vectors, vec1 and vec2.
We then use the extend method of vec1 to extend it with elements of vec2.
The result is a new vector result containing elements from both vec1 and vec2.

Rust Program

fn main() {
    let mut vec1 = vec![1, 2, 3];
    let vec2 = vec![4, 5, 6];
    vec1.extend(vec2);
    println!("Joined Vector: {:?}", vec1);
}

Output

Joined Vector: [1, 2, 3, 4, 5, 6]
