Error

Fix the error by ensuring the data being borrowed outlives the reference, typically by moving the data creation before the reference is used or by returning the owned data instead of a reference.

fn main() {
    let data = String::from("hello");
    let reference = &data;
    println!("{}", reference);
}

In this example, data is created before reference is made, ensuring data lives long enough for reference to be valid. If you were returning a reference to a local variable, change the function to return the owned value (e.g., String) instead.

The "borrowed value does not live long enough" error means you are trying to use a piece of data after it has been deleted or is no longer available. Think of it like trying to read a book that has already been thrown away; the book must exist while you are reading it. To fix it, make sure the data is created before you try to use it and isn't destroyed until you are done.
