How to get Sub Vector in Rust - Step by Step Examples

How to get Sub Vector in Rust ?

To get a sub-vector in Rust, you can use slicing.

In this example,

We have a vector named vec containing elements.
We specify the range of indices of the elements we want to extract using slicing syntax [start_index..end_index].
We assign the extracted sub-vector to a new variable named sub_vec.
Finally, we print the sub-vector sub_vec to standard output.

fn main() {
    let vec = vec![1, 2, 3, 4, 5];
    let sub_vec = &vec[1..3];
    println!("{:?}", sub_vec);
}
