rustHow to insert into a slice in Rust?

Inserting into a slice in Rust is done using the insert() method. This method takes two arguments, the index at which to insert the element and the element to be inserted.

Example

let mut my_slice = [1, 2, 3];
my_slice.insert(1, 4);

Output example

[1, 4, 2, 3]

Code explanation

• let mut my_slice = [1, 2, 3];: This declares a mutable slice called my_slice with elements 1, 2, and 3.
• my_slice.insert(1, 4);: This calls the insert() method on my_slice, inserting the element 4 at index 1.
