In the current documentation about the `Copy` marker trait, there is a section with examples of structs that can implement `Copy`. Currently there is no example for showing that shared references (`&T`) are also `Copy`. It is worth to have a dedicated example for `&T` being `Copy`, because shared references are an integral part of the language and it being `Copy` is not as intuitive as other types that share this behaviour like `i32` or `bool`. The example picks up on the previous non-`Copy` struct and shows that structs can be `Copy`, even when they hold a shared reference to a non-`Copy` type. |
