Suggest borrowing on fn argument that is `impl AsRef` When encountering a move conflict, on an expression that is `!Copy` passed as an argument to an `fn` that is `impl AsRef`, suggest borrowing the expression. ``` error[E0382]: use of moved value: `bar` --> f204.rs:14:15 | 12 | let bar = Bar; | --- move occurs because `bar` has type `Bar`, which does not implement the `Copy` trait 13 | foo(bar); | --- value moved here 14 | let baa = bar; | ^^^ value used here after move | help: borrow the value to avoid moving it | 13 | foo(&bar); | + ``` Fix #41708 |
