11545: add `is_slice` method to `hir::Type` r=flodiebold a=nerdypepper
would like to have this on `hir::Type` for a small project i am working on, unless there is another way to check if `hir::Type` is a slice primitive?

11461: Extract struct from enum variant filters generics r=jo-goro a=jo-goro
Fixes#11452.
This PR updates extract_struct_from_enum_variant. Extracting a struct `A` form an enum like
```rust
enum X<'a, 'b> {
A { a: &'a () },
B { b: &'b () },
}
```
will now be correctly generated as
```rust
struct A<'a> { a: &'a () }
enum X<'a, 'b> {
A(A<'a>),
B { b: &'b () },
}
```
instead of the previous
```rust
struct A<'a, 'b>{ a: &'a () } // <- should not have 'b
enum X<'a, 'b> {
A(A<'a, 'b>),
B { b: &'b () },
}
```
This also works for generic type parameters and const generics.
Bounds are also copied, however I have not yet implemented a filter for unneeded bounds. Extracting `B` from the following enum
```rust
enum X<'a, 'b: 'a> {
A { a: &'a () },
B { b: &'b () },
}
```
will be generated as
```rust
struct B<'b: 'a> { b: &'b () } // <- should be `struct B<'b> { b: &'b () }`
enum X<'a, 'b: 'a> {
A { a: &'a () },
B(B<'b>),
}
```
Extracting bounds with where clauses is also still not implemented.

11513: internal: Expand the derive attribute into a pseudo expansion r=Veykril a=Veykril
Quoting my comment:
> We generate a very specific expansion here, as we do not actually expand the `#[derive]` attribute
> itself in name res, but we do want to expand it to something for the IDE layer, so that the input
> derive attributes can be downmapped, and resolved as proper paths.
> This is basically a hack, that simplifies the hacks we need in a lot of ide layer places to
> somewhat inconsistently resolve derive attributes.
>
> As such, we expand `#[derive(Foo, bar::Bar)]` into
> ```
> #[Foo]
> #[bar::Bar]
> ();
> ```
> which allows fallback path resolution in hir::Semantics to properly identify our derives.
> Since we do not expand the attribute in nameres though, we keep the original item.
>
> The ideal expansion here would be for the `#[derive]` to re-emit the annotated item and somehow
> use the input paths in its output as well.
> But that would bring two problems with it, for one every derive would duplicate the item token tree
> wasting a lot of memory, and it would also require some way to use a path in a way that makes it
> always resolve as a derive without nameres recollecting them.
> So this hacky approach is a lot more friendly for us, though it does require a bit of support in
> [`hir::Semantics`] to make this work.

installation section as opposed to the Troubleshooting section.

11490: Correctly fix formatting doc tests with generics r=Veykril a=KarlWithK
Before the doc_test would be outputted like this:
```zsh
"Foo<T, U>::t"
```
However, this would cause problems with shell redirection. I've changed it
so when generics are involved we simply wrap the expression under quotes as so:
```zsh
"\"Foo<T, U>::t\""
```
Note:
At the cost of adding this, I had to allocate a new string via
`format!{}`. However, I argue this is alright as this for just for
outputting the name of the doc test.
The following tests have been changed:
```
runnables::tests::doc_test_type_params
runnables::tests::test_doc_runnables_impl_mod
runnables::tests::test_runnables_doc_test_in_impl
```

11481: Display parameter names when hovering over a function pointer r=Veykril a=Vannevelj
Implements #11474
The idea is pretty straightforward: previously we constructed the hover based on just the parameter types, now we pass in the parameter names as well. I went for a quick-hit approach here but I expect someone will be able to point me to a better way of resolving the identifier.
I haven't figured out yet how to actually run my rust-analyzer locally so I can see it in action but the unit test indicates it should work.
