``` error[E0499]: cannot borrow `foo` as mutable more than once at a time --> $DIR/suggest-split-at-mut.rs:13:18 | LL | let a = &mut foo[..2]; | --- first mutable borrow occurs here LL | let b = &mut foo[2..]; | ^^^ second mutable borrow occurs here LL | a[0] = 5; | ---- first borrow later used here | = help: use `.split_at_mut(position)` or similar method to obtain two mutable non-overlapping sub-slices ``` Address most of #58792. For follow up work, we should emit a structured suggestion for cases where we can identify the exact `let (a, b) = foo.split_at_mut(2);` call that is needed. |
