Can someone explain where the second part of the suggestion (}) went?

I thought that it'd show multiple parts :(

I think this is a bug in the rendering code. Your suggestion is still MachineApplicable so it will apply just fine, it's just the rendered code will be cut off.
I don't know if there's much you can do to fix it in this PR specifically, but maybe you could file a bug, or look into fixing the rendering code to omit lines in the middle?

It's not a "bug", but rather a non-implementation of the logic for multiple "windows" into the code, like span labels have.

This looks basically read to go. Can you fix a few more nits? Thanks!

Can you actually use ? here, move the body of the closure to below, and remove the ? on line 1614?

All other if branches also return Results, so I don't think it makes sense to do that

Oh, oops, I thought there was only two if branches. I should've clicked the button to reveal the lines above 😓

…that_are_quite_far_away_from_each_other, r=estebank Hide irrelevant lines in suggestions to allow for suggestions that are far from each other to be shown This is an attempt to fix suggestions one part of which is 6 lines or more far from the first. I've noticed "the problem" (of not showing some parts of the suggestion) here: rust-lang#97759 (comment). I'm not sure about the implementation (this big closure is just bad and makes already complicated code even more so), but I want to at least discuss the result. Here is an example of how this changes the output: Before: ```text help: consider enclosing expression in a block | 3 ~ 'l: { match () { () => break 'l, 4 | 5 | 6 | 7 | 8 | ... ``` After: ```text help: consider enclosing expression in a block | 3 ~ 'l: { match () { () => break 'l, 4 | ... 31| 32~ } }; | ``` r? `@estebank` `@rustbot` label +A-diagnostics +A-suggestion-diagnostics
