"temporary value dropped while borrowed"

[matthew-a-thomas]

use ansi_rgb::{ Background, Foreground, red, green };

fn main() {
    let foo = "Hello, world!".fg(green()).bg(red());
    println!("{}", foo);
}

Output:

error[E0716]: temporary value dropped while borrowed
 --> src\main.rs:4:15
  |
4 |     let foo = "Hello, world!".fg(green()).bg(red());
  |               ^^^^^^^^^^^^^^^^^^^^^^^^^^^          - temporary value is freed at the end of this statement
  |               |
  |               creates a temporary which is freed while still in use
5 |     println!("{}", foo);
  |                    --- borrow later used here
  |
  = note: consider using a `let` binding to create a longer lived value

Maybe implement Foreground and Background for T instead of &T. I think it will most often be used on &str which is Copy already, so it doesnt get moved.
