Need clarity on passing strings to functions

help
1

When I do this:

fn print_me(msg: &str) {
    println!("msg = {}", msg);
}

pub fn main() {
    print_me("Wow!");
}

All is well, but I'm passing a reference to a string literal, not a variable having a lifetime elsewhere. What happens to the reference after the function finishes? Does the lifetime of the string literal end after the function completes?

The string literal has type &'static str since it's a reference to the UTF-8 encoded text data packed with the program binary itself. This portion of memory will not be unloaded until the process be terminated, hence the 'static lifetime means.
