bors 879fb42596 Auto merge of #96431 - petrochenkov:parent, r=cjgillot ... rustc: Panic by default in `DefIdTree::parent` Only crate root def-ids don't have a parent, and in majority of cases the argument of `DefIdTree::parent` cannot be a crate root. So we now panic by default in `parent` and introduce a new non-panicing function `opt_parent` for cases where the argument can be a crate root. Same applies to `local_parent`/`opt_local_parent`.		2022-05-02 14:03:20 +00:00
