How to get Sub Array in Rust ?

Answer

To get a sub-array in Rust, you can use slicing on arrays or vectors.

✐ Examples

1 Sub-array of Integer Array

In this example,

We create an integer array named numbers with some values.
We then use slicing to get a sub-array from index 2 to index 4 (inclusive).
Finally, we print the sub-array.

Rust Program

fn main() {
    let numbers = [1, 2, 3, 4, 5];
    let sub_array = &numbers[2..=4];
    println!("Sub-array: {:?}", sub_array);
}

Output

Sub-array: [3, 4, 5]

2 Sub-array of Character Array

In this example,

We create a character array named characters with some values.
We then use slicing to get a sub-array from index 1 to index 3 (inclusive).
Finally, we print the sub-array.

Rust Program

fn main() {
    let characters = ['a', 'b', 'c', 'd', 'e'];
    let sub_array = &characters[1..=3];
    println!("Sub-array: {:?}", sub_array);
}

Output

Sub-array: ['b', 'c', 'd']
