I don’t know the dbus crate, so I’m not trying to say anything about that crate’s usage, I’m simply saying that referencing after dereferencing is idiomatic Rust.

For example, the standard library `String` type dereferences to `str` which you can then re-reference to `&str`.

Sorry, I should have been clearer in my question, I wanted to know about A deref to B re-ref to &B.

ameliaquining awnsered my question and you modulated my opinion, that pattern is can be idiomatic when the principle of minimal surprises is respected.
