What about a more permanent solution in the diagnostics infra? |

Yes, I think that's sound advice. It can help us eliminate duplicate suggestions. |

It's worth noting that for this case, there's a duplicate label generated by placeholder_types. As we did previously, the method to eliminate the duplication is to add placeholder_types.dedup().

Should we dedup after sorting? In case we have [(first span, first stuff), (second span, second stuff), (first span, first stuff)].

Great tips! Before this, I always assumed that Vec::dedup was equivalent to Vec::from(HashSet::from(vector)).

Please do not sort suggestions twice. They are already sorted by span a few lines below.

…mpiler-errors Fix the dedup error because of spans from suggestion Fixes rust-lang#116502 I believe this kind of issue is supposed resolved by rust-lang#118057, but the `==` in `span` respect syntax context, here we should only care that they point to the same bytes of source text, so should use `source_equal`.
