Sorry for being nitpicky, but can you add some spaces next to the braces? It bugs me a little. |
No problem - it's done. |

this could be an if let or if ... == StructKind::Unit

Just changed it. Out of curiosity - what makes if let preferable? Just that it's more concise? I would think it a lot of situations match without a default is better because you'll get a compiler error if a new variant is added which forces you to explicitly decide how to handle the new variant. Of course, that doesn't really apply here because StructKind isn't likely to change.

I think in this case, as you said, StructKind isn't likely to change, and we just want to handle the unit case as a special case here.

3169: Show record field names in Enum completion r=flodiebold a=adamrk Adresses #2947. Previously the details shown when autocompleting an Enum variant would look like the variant was a tuple even if it was a record:  This change will show the names of the fields for a record and use curly braces instead of parentheses:  This required exposing the type `adt::StructKind` from `ra_hir` and adding a function ``` kind(self, db: &impl HirDatabase) -> StructKind ``` in the `impl` of `EnumVariant`. There was also a previously existing function `is_unit(self, db: &impl HirDatabase) -> bool` for `EnumVariant` which I removed because it seemed redundant after adding `kind`.
