| - ^ ---------- &str

| | `+` cannot be used to concatenate two `&str` strings
| &str
help: `to_owned()` can be used to create an owned `String` from a string reference. String concatenation appends the string on the right to the string on the left and may require reallocation. This requires ownership of the string on the left
