6586: Don't call a closure a function in the infer_function_return_type assist label r=lnicola a=Veykril
`Add this function's return type` becomes `Add this closure's return type` for closures. This makes it more obvious that we are indeed planning on modifying the closure and not its containing function.

6553: Auto imports in completion r=matklad a=SomeoneToIgnore
![completion](https://user-images.githubusercontent.com/2690773/99155339-ae4fb380-26bf-11eb-805a-655b1706ce70.gif)
Closes https://github.com/rust-analyzer/rust-analyzer/issues/1062 but does not handle the completion order, since it's a separate task for https://github.com/rust-analyzer/rust-analyzer/issues/4922 , https://github.com/rust-analyzer/rust-analyzer/issues/4922 and maybe something else.
2 quirks in the current implementation:
* traits are not auto imported during method completion
If I understand the current situation right, we cannot search for traits by a **part** of a method name, we need a full name with correct case to get a trait for it.
* VSCode (?) autocompletion is not as rigid as in Intellij Rust as you can notice on the animation.
Intellij is able to refresh the completions on every new symbol added, yet VS Code does not query the completions on every symbol for me.
With a few debug prints placed in RA, I've observed the following behaviour: after the first set of completion suggestions is received, next symbol input does not trigger a server request, if the completions contain this symbol.
When more symbols added, the existing completion suggestions are filtered out until none are left and only then, on the next symbol it queries for completions.
It seems like the only alternative to get an updated set of results is to manually retrigger it with Esc and Ctrl + Space.
Despite the eerie latter bullet, the completion seems to work pretty fine and fast nontheless, but if you have any ideas on how to make it more smooth, I'll gladly try it out.

6477: Add infer_function_return_type assist r=matklad a=Veykril
This adds an assist to insert a functions return type if it hasn't been specified yet by inferring it from the functions tail expression. This assist only becomes active if the cursor is on the tail expression. See https://github.com/rust-analyzer/rust-analyzer/issues/6303#issuecomment-714657326

This also prevents the assist from being disabled if a definition in the value namespace exists with the same name as our new struct since that won't cause a collision

6458: Qualify trait impl created by add_custom_impl assist r=matklad a=Veykril
When we find at least one trait with the same name as the derive accessible from the current module we now generate a qualified path to that trait in the generated impl.
If we don't find any we just do what was done before and emit the trait name in the generated impl.

This also seizes the opportunity to move integer literal parsing to
the syntax crate, were it logically belongs.
Note though that this is still done in an ad hoc manner -- we probably
should split kitchen sink ast::Literal into a separate APIs for
strings, ints, etc
6393: Remove repetitive inlay hints (take 2) r=matklad a=lnicola
6399: Keep generic annotations when qualifying things r=matklad a=Veykril
The `qualify_path` assists currently eats up already annotated generics in all but one cases which can be annoying if one already pre-fills generics of a type before it's been qualified.

6331: correct hover text for items with doc attribute with raw strings r=matklad a=JoshMcguigan
Fixes#6300 by improving the handling of raw string literals in attribute style doc comments.
This still has a bug where it could consume too many `"` at the start or end of the comment text, just as the original code had. Not sure if we want to fix that as part of this PR or not? If so, I think I'd prefer to add a unit test for either the `as_simple_key_value` function (I'm not exactly sure where this would belong / how to set this up) or create a `fn(&SmolStr) -> &SmolStr` to unit test by factoring out the `trim` operations from `as_simple_key_value`. Thoughts on this?
6342: Shorter dependency chain r=matklad a=popzxc
Continuing implementing suggestions from the `Completion refactoring` zulip thread.
This PR does the following:
- Removes dependency of `completions` on `assists` by moving required functionality into `ide_db`.
- Moves completely `call_info` crate into `ide_db` as it looks like it fits perfect there.
- Adds a bunch of new tests and docs.
- Adds the re-export of `base_db` to the `ide_db` and removes direct dependency on `base_db` from other crates.
The last point is controversial, I guess, but I noticed that in places where `ide_db` is used, `base_db` is also *always* used. Thus I think the dependency on the `base_db` is implied by the fact of `ide_db` interfaces, and thus it makes sense to just provide `base_db` out of the box.

6172: Add qualify path assist r=matklad a=Veykril
This implements a `qualify_path` assist which works quite similar to the `auto_import` assist but instead of adding imports to the file it well, qualifies the path. This PR also moves out the `AutoImportAssets` struct and functions from `auto_import` into a utils submodule as most of this is now shared between `auto_import` and `qualify_path`.
Changes made to `AutoImportAssets` are solely in its `search_for_imports` function which now takes a prefixed parameter to discern between using `find_use_path_prefixed` and `find_use_path` as the former is the required behavior by `auto_import` and the latter by this assist.
For missing imported traits instead of importing this will qualify the path with a trait cast as in:
```rust
test_mod::TestStruct::TEST_CONST<|>
```
becomes
```rust
<test_mod::TestStruct as test_mod::TestTrait>::TEST_CONST
```
and for trait methods ideally it would do the following:
```rust
let test_struct = test_mod::TestStruct {};
test_struct.test_meth<|>od()
```
becomes
```rust
let test_struct = test_mod::TestStruct {};
test_mod::TestTrait::test_method(&test_struct)
```
Fixes#4124.

Declaration names sounds like a name of declaration -- something you
can use for analysis. It empathically isn't, and is just a label
displayed in various UI. It's important not to confuse the two, least
we accidentally mix semantics with UI (I believe, there's already a
case of this in the FamousDefs at least).
6207: Extract ImportAssets out of auto_import r=matklad a=Veykril
See https://github.com/rust-analyzer/rust-analyzer/pull/6172#issuecomment-707182140
I couldn't fully pull out `AssistContext` as `find_node_at_offset_with_descend`: 81fa00c5b5/crates/assists/src/assist_context.rs (L90-L92) requires the `SourceFile` which is private in it and I don't think making it public just for this is the right call?

6130: Items case quick fix (snake_case / UPPER_SNAKE_CASE / CamelCase) r=matklad a=popzxc
Resolves#4598.
After a third try, it finally works. Boy, it appeared tougher than it seemed.
Initially I thought like "Ha, `rustc` already tells us where idents are named incorrectly. It shouldn't be that hard, should it?".
Well, the problems with the information provided by `rustc` appeared shortly:
- `rustc` warnings are `flycheck` warnings, which are slightly aside from our diagnostics with fixes.
When we map flycheck diagnostic to LSP, we can convert it into a fix, but only if it's marked as `Applicability::MachineApplicable`.
Name case fix is marked `Applicability::MaybeIncorrect`, and for a reason: it only suggest to rename symbol under cursor, without tracking any references.
- Warning spawned by `rustc` are identified by string labels rather than enum. It means that if one day the diagnostic will be renamed in `rustc`, `rust-analyzer` code will still compile, but won't find the required diagnostic by name anymore. If by chance this will happen when some unlucky guy will decide to create their first pull request, they'll be confused by suddenly failing tests (likely) not related to their changes.
- Even if we'll try to build fixes atop of `rustc` warnings, we'll have to do it in the `rust_analyzer::diagnostics::to_proto` module, which is far less
convenient for that matter than `ide` crate.
That's why I decided that it's worth a separate `rust-analyzer` diagnostic, which will implement `DiagnosticWithFix` trait.
After that, I discovered that currently `hir_ty::diagnostics` only check `DefWithBody` types, like function bodies. I had to add support for diagnostics
which look at any `ModuleDef`.
And of course, since I'd added a lot of new functionality, it required extensive testing.
That explains why the diff is so big for a (looking) relatively small feature.
I hope that this PR doesn't only add a small feature, but also creates a base for building another features.
## Example:

P.S. My eyes were bleeding when I had to write the code for the example...
6135: when generating new function, focus on return type instead of body r=matklad a=bnjjj
I made a little change when we use the assist to generate a new function, instead of focusing on the function body, it will focus on return type

Previously, "find all references" on a variant field wouldn't find any
references outside the defining module. This is because variant fields
were incorrectly assumed to be private, like struct fields without
explicit visibility, but they actually inherit the enum's visibility.
6139: Make find_path_prefixed configurable r=matklad a=Veykril
This makes `find_path_prefixed` more configurable allowing one to choose whether it always returns absolute paths, self-prefixed paths or to ignore local imports when building the path.
The config names are just thrown in here, taking better names if they exist :)
This should fix#6131 as well?

5989: Rewrite import merging r=jonas-schievink a=Veykril
Rewrites how import merging is being handled. It is now a recursive function to properly handle merging of intermediate levels in the import trees. With this ordering the imports is also now possible tho it doesn't quite order it the same way as `rustfmt` does yet, namely it orders lowercase identifiers after uppercase identifiers as that is the standard character order that rust uses. This also fixes a few weird behaviors that were visible in some of the `replace_qualified_name_with_use.rs` tests.
This really took longer than I was hoping for, fighting with import trees is quite the exhausting task 😅
