Make ItemKind::ExternCrate looks like hir::ItemKind::ExternCrate to make transition over hir::ItemKind simpler #80845

GuillaumeGomez · 2021-01-09T17:30:36Z

It was surprisingly difficult to make this change, mostly because of two issues:

We now store the ExternCrate name in the parent struct (clean::Item), which forced me to modify the json conversion code a bit more than expected.
The second problem was that, since we now have a Some(name), it was trying to render it, ending up in a panic because we ended up in a unreachable statement. The solution was simply to add !item.is_extern_crate() in formats::renderer before calling cx.item(item, &cache)?;.

I'll continue to replace all the clean::ItemKind variants one by one until it looks exactly like hir::ItemKind. Then we'll simply discard the rustdoc type. Once this done, we'll be able to discard clean::Item too to use hir::Item.

…ields, r=ollie27 Remove some function fields Same kind as rust-lang#80845. This PR removes the `all_types` and `ret_types` from the `clean::Function` type. Another change that I had to do was implementing the `From` trait to be able to convert `hir::def::DefKind` into `clean::TypeKind` without requiring `DocContext` (and so I updated the `clean` method so that it's taken into account). The last two commits improve a bit the `get_real_types` function and the `Type::generics` method. r? `@jyn514`

I like the idea but the implementation needs some work.

I'll go forward with this then! If you want the test back, don't hesitate to ask (either before after it's merged).

@bors r-

You didn't fix the panic:

This will panic if you pass a StrippedItem(ExternCrateItem).

GuillaumeGomez · 2021-02-26T14:50:42Z

Good catch, thanks!

GuillaumeGomez · 2021-02-26T21:59:25Z

@jyn514: I went for what you suggested: I now pass the name argument to the function so we can now handle ExternCrateItem into it directly.

Yup, this is what I was expecting, thanks :)
