Create a string from a byte array, but the result isnāt a string, itās a cow š®, so you need another to_string() to convert your āstringā into a string.

I still have a lot to learn.
(into_owned() instead of to_string() also works and makes more sense to me, itās just that the compiler suggested to_string() first, which led to this funny example.)
