# Objective Fix unsound lifetimes in `Query::join` and `Query::join_filtered`. The joined query allowed access from either input query, but it only took the `'world` lifetime from `self`, not from `other`. This meant that after the borrow of `other` ended, the joined query would unsoundly alias `other`. ## Solution Change the lifetimes on `join` and `join_filtered` to require mutable borrows of the *same* lifetime for the input queries. This ensures both input queries are borrowed for the full lifetime of the joined query. Change `join_inner` to take `other` by value instead of reference so that the returned query is still usable without needing to borrow from a local variable. ## Testing Added a compile-fail test. |
