Why can't you store a value and a reference to it in the same struct in Rust?

Hi everyone! I started learning Rust and encountered a problem that really puzzled me. I'm trying to write a struct that stores some data and at the same time a reference to that data inside itself. For example, I want to create a struct that contains a string and its first character — a reference to that string. Here's what I'm trying to do: ```rust struct MyStruct { data: String, first_char: &str, // reference to data } fn main() { let text = String::from("Hello"); let first = &text[..1]; let s = MyStruct { data: text, first_char: first }; println!("{}", s.first_char); } ``` The compiler gives an error: `error[E0382]: borrow of moved value: 'text'`. I understand that when I move `text` into the struct, I can no longer use `first` because it references
