rustHow to pass a Rust slice as a function parameter?

Passing a Rust slice as a function parameter is done by using the &[T] syntax. This syntax indicates that the function takes a slice of type T. For example:

fn print_slice(slice: &[i32]) {
    for item in slice {
        println!("{}", item);
    }
}

let arr = [1, 2, 3];
print_slice(&arr);

Output example

1
2
3

• fn print_slice(slice: &[i32]): This declares a function called print_slice that takes a slice of type i32 as a parameter.
• let arr = [1, 2, 3]: This creates an array of type i32 with the values 1, 2, and 3.
• print_slice(&arr): This passes the array arr as a parameter to the function print_slice.
