"{N} Implementations" hint is repeated

[landaire]

When examining a struct generated with ouroboros, the hint specifying the number of implementations is repeated as shown in this screenshot:

To reproduce, clone ouroboros:

$ git clone https://github.com/joshua-maros/ouroboros

Then view one of the examples in examples/src/lib.rs.

I think this probably surfaces as a side effect of the crate's code generation, but clicking any of the repeated "implementations" hints shows exactly the same data.

In the attached screenshot, is it repeated 8 times (once per implementation)?

It seems to be repeated infinitely based on editor width. In my own project where I first noticed it, there are 9 implementations but I counted at least 9. There are also at least 9 in the screenshot I attached. This video shows it a bit better

seems not infinitely repeated for all case

Cause is most likely that the struct name's span is being reused for a bunch of other ADT defs / trait definitions. A bit weird that such an impl here affects all of them though nevermind I know why that is. We should probably only check for the same identifier mapping here.

@Veykril thanks for taking a look and for the the quick fix!
