rustHow to append to a Rust slice?

Appending to a Rust slice can be done using the push() method. This method takes a single argument and adds it to the end of the slice.

let mut my_slice = vec![1, 2, 3];
my_slice.push(4);
println!("{:?}", my_slice);

Output example

[1, 2, 3, 4]

The push() method takes a single argument and adds it to the end of the slice:

• my_slice: The slice to which the element should be appended.
• 4: The element to be appended to the slice.
