Add 'static lifetime suggestion when GAT implied 'static requirement from HRTB Fix for issue #105507 The problem: When generic associated types (GATs) are from higher-ranked trait bounds (HRTB), they are implied 'static requirement (see [Implied 'static requirement from higher-ranked trait bounds](https://blog.rust-lang.org/2022/10/28/gats-stabilization.html#implied-static-requirement-from-higher-ranked-trait-bounds) for more details). If the user did not explicitly specify the `'static` lifetime when using the GAT, the current error message will only point out the type `does not live long enough` where the type is used, but not where the GAT is specified and how to fix the problem. The solution: Add notes at the span where the problematic GATs are specified and suggestions of how to fix the problem by adding `'static` lifetime at the right spans. |
