11686: feat: Enum variant field completion, enum variant / struct consistency r=Veykril a=m0rg-dev
This addresses several related inconsistencies:
- tuple structs use tab stops instead of placeholders
- tuple structs display in the completion menu as `Struct {…}` instead of `Struct(…)`
- enum variants don't receive field completions at all
- enum variants display differently from structs in the completion menu
Also, structs now display their type in the completion detail rather than the raw snippet text to be inserted.
As far as what's user-visible, that looks like this:
| | Menu | Completion | Detail |
|-|-|-|-|
| Record struct (old) | `Struct {…}` | `Struct { x: ${1:()}, y: ${2:()} }$0` | `Struct { x: ${1:()}, y: ${2:()} }$0` |
| Record struct (new) | `Struct {…}` | `Struct { x: ${1:()}, y: ${2:()} }$0` | `Struct { x: i32, y: i32 }` |
| Tuple struct (old) | `Struct {…}` | `Struct($1, $2)$0` | `Struct($1, $2)` |
| Tuple struct (new) | `Struct(…)` | `Struct(${1:()}, ${2:()})$0` | `Struct(i32, i32)` |
| Unit variant (old) | `Variant` | `Variant` | `()` |
| Unit variant (new) | `Variant` | `Variant$0` | `Variant` |
| Record variant (old) | `Variant` | `Variant` | `{x: i32, y: i32}` |
| Record variant (new) | `Variant {…}` | `Variant { x: ${1:()}, y: ${2:()} }$0` | `Variant { x: i32, y: i32 }` |
| Tuple variant (old) | `Variant(…)` | `Variant($0)` | `(i32, i32)` |
| Tuple variant (new) | `Variant(…)` | `Variant(${1:()}, ${2:()})$0` | `Variant(i32, i32)` |
Additionally, tuple variants no longer set `triggers_call_info` because it conflicts with placeholder generation, and tuple variants that require a qualified path should now use the qualified path.
Internally, this also lets us break the general "format an item with fields on it" code out into a shared module, so that means it'll be a lot easier to implement features like #11568.

In particular:
- unit variants now display in the menu as "Variant", complete to "Variant", and display a detail of "Variant" (was "()")
- tuple variants now display in the menu as "Variant(…)", complete to "Variant(${1:()})$0" (was "Variant($0)"), and display a detail of "Variant(type)" (was "(type)")
- record variants now display in the menu as "Variant {…}", complete to "Variant { x: ${1:()} }$0" (was "Variant"), and display a detail of "Variant { x: type }" (was "{x: type}")
This behavior is identical to that of struct completions. In addition, tuple variants no longer set triggers_call_info, as to my understanding it's unnecessary now that we're emitting placeholders.
Tests have been updated to match, and the render::enum_variant::tests::inserts_parens_for_tuple_enums test has been removed entirely as it's covered by other tests (render::enum_detail_includes_{record, tuple}_fields, render::enum_detail_just_name_for_unit, render::pattern::enum_qualified).
- Add support for placeholder completions in tuple structs
- Denote tuple struct completions with `(…)` instead of ` {…}`
- Show struct completions as their type (`Struct { field: Type }`) in the completion menu instead of raw snippet text (`Struct { field: ${1:()} }$0`)
It wasn't testing the `const_arg` code path, it was actually hitting
const_param's default value code path, so move it to the right place
and rename it.

11662: fix: extract_module selection inside impl r=Veykril a=feniljain
Should close: #11508
From issue:
Concern 1: Seems to be fixed in latest `rust-analyzer` build
Concern 2 and 3: Should be fixed by this PR
Concern 4: Got fixed in #11472
Points to note:
- Here I have seperated use items and other items, this is becuase the new `impl` block which we will be creating cannot contain use items as immediate children. As they are the only one item that can be generated by our assist, so seperating them helps in handling their inclusion in new `impl` block inside new `module`
- There's also a new method added which helps in removing remaning left over indentation after removing `impl` or other `item`

11663: Internal: Add hir_def::MacroId, add Macro{Id} to ModuleDef{Id} r=Veykril a=Veykril
With this we can now handle macros like we handle ModuleDefs making them work more like other definitions and allowing us to remove a bunch of special cases. This also enables us to track the modules these macros are defined in, instead of only recording the crate they come from.
Introduces a new class of `MacroId`s (for each of the 3 macro kinds) into `hir_def`. We can't reuse `MacroDefId` as that is defined in `hir_expand` which doesn't know of modules, so now we have two different macro ids, this unfortunately requires some back and forth mapping between the two via database accesses which I hope won't be too expensive.

11445: Upstream inlay hints r=lnicola a=lnicola
Closes https://github.com/rust-analyzer/rust-analyzer/issues/2797
Closes https://github.com/rust-analyzer/rust-analyzer/issues/3394 (since now resolve the hints for the range given only, not for the whole document. We don't actually resolve anything due to [hard requirement](https://github.com/rust-analyzer/rust-analyzer/pull/11445#issuecomment-1035227434) on label being immutable. Any further heavy actions could go to the `resolve` method that's now available via the official Code API for hints)
Based on `@SomeoneToIgnore's` branch, with a couple of updates:
- I squashed, more or less successfully, the commits on that branch
- downloading the `.d.ts` no longer works, but you can get it manually from https://raw.githubusercontent.com/microsoft/vscode/release/1.64/src/vscode-dts/vscode.proposed.inlayHints.d.ts
- you might need to pass `--enable-proposed-api matklad.rust-analyzer`
- if I'm reading the definition right, `InlayHintKind` needs to be serialized as a number, not string
- this doesn't work anyway -- the client-side gets the hints, but they don't display

11598: feat: Parse destructuring assignment r=Veykril a=ChayimFriedman2
Part of #11532.
Lowering is not as easy and may not even be feasible right now as it requires generating identifiers: `(a, b) = (b, a)` is desugared into
```rust
{
let (<gensym_a>, <gensym_b>) = (b, a);
a = <gensym_a>;
b = <gensym_b>;
}
```
rustc uses hygiene to implement that, but we don't support hygiene yet.
However, I think parsing was the main problem as lowering will just affect type inference, and while `{unknown}` is not nice it's much better than a syntax error.
I'm still looking for the best way to do lowering, though.
Fixes#11454.

11623: fix: Add type variable table to InferenceTableSnapshot r=flodiebold a=tysg
Fixes#11601.
I observed that removing the `rollback` line in 6fc3d3aa4c fixes the issue.
Looking at the stacktrace, I believe not restoring `type_variable_table` causes `type_variable_table` and `var_unification_table` to go out of sync, then when `hir_ty::infer::unify::InferenceTable::new_var` tries to extend `type_variable_table` to be the same length as `var_unification_table`, problems will arise.
However, I cannot pinpoint exactly how or where the vector capacity overflow happens, so my understanding might not be correct after all.

11550: Refactor autoderef/method resolution r=flodiebold a=flodiebold
- don't return the receiver type from method resolution; instead just
return the autorefs/autoderefs that happened and repeat them. This
ensures all the effects like trait obligations and whatever we learned
about type variables from derefing them are actually applied. Also, it
allows us to get rid of `decanonicalize_ty`, which was just wrong in
principle.
- Autoderef itself now directly works with an inference table. Sadly
this has the effect of making it harder to use as an iterator, often
requiring manual `while let` loops. (rustc works around this by using
inner mutability in the inference context, so that things like unifying
types don't require a unique reference.)
- We now record the adjustments (autoref/deref) for method receivers
and index expressions, which we didn't before.
- Removed the redundant crate parameter from method resolution, since
the trait_env contains the crate as well.
- in the HIR API, the methods now take a scope to determine the trait env.
`Type` carries a trait env, but I think that's probably a bad decision
because it's easy to create it with the wrong env, e.g. by using
`Adt::ty`. This mostly didn't matter so far because
`iterate_method_candidates` took a crate parameter and ignored
`self.krate`, but the trait env would still have been wrong in those
cases, which I think would give some wrong results in some edge cases.
Fixes#10058.

This keeps track of the relevant attributes and adds in a wildcard pat at the end of the match when necessary.
I decided to do them in the same PR since they both needed the ability to add a wildcard arm, and so their changes would overlap if done separately, but I'll split them up if that seems better.
This is my first PR to rust-analyzer, so all feedback is greatly appreciated!

Fixes https://github.com/rust-analyzer/rust-analyzer/issues/10253#issuecomment-920962927
(the same issue probably exists for method calls, but I think fixing that might be trickier)
Visibility checks were introduced in https://github.com/rust-analyzer/rust-analyzer/issues/7841 for autoderef to work properly, so now we just record the first field we find unconditionally, and then overwrite it if autoderef manages to find another field in a later cycle.

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.

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:
```

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.
