Word choice: I think "exists" feels less stilted than "resolves" here.

Is it possible to move the "no baz in zed" message into the main error message and have the help end up in the position that it was previously? Not sure if our emitters will do that though.

Do you mean an error message like:
-> $DIR/import.rs:2:5
|
LL | use zed::baz; //~ ERROR unresolved import: no `baz` in `zed` [E0432]
| --- help: a similar name exists in the module: `bar`

oh yea, that's even better than what I had in mind.

Well, my idea won't work with the multi-import case, though.

That message still has the no bay in zed messages, if we eliminate them entirely, at least one of the help messages should show up in the correct space

Right, that's the output of my code as it stands. I think that removing the label entirely would regress the error message if there's no suggestion. I'm not sure that making them mutually exclusive would be better, either. @estebank, what do you think?

I think that for the last case shown here it is best to be conservative (and verbose). An option you have @euclio is to use span_suggestion_hidden (#58296) to display only the message without the code snippet, but you would have to explicitly write the found identifier in the message to be usable from the cli output (as opposed to VSCode):
error[E0432]: unresolved imports `zed::baz`, `zed::bay`
--> src/test/ui/import.rs:7:11
|
7 | use zed::{baz, bay};
| ^^^ ^^^ no `bay` in `zed`
| |
| no `baz` in `zed`
= help: `bar`, which is similar to `baz`, exists in `zed`
= help: `bar`, which is similar to `bay`, exists in `zed`
It'd be also neat to collect the suggestions to avoid suggesting the same name multiple times, but that's gold plating.

Feel free not to do this, I think that the output as is is already pretty good (modulo Zack's wording comments).

@estebank I've fixed the wording suggestions. I think I'll leave the label improvements to a future PR. |
