Today, rust-analyzer (and rustc, and bat, and IntelliJ) fail badly on
some kinds of maliciously constructed code, like a deep sequence of
nested parenthesis.
"Who writes 100k nested parenthesis" you'd ask?
Well, in a language with macros, a run-away macro expansion might do
that (see the added tests)! Such expansion can be broad, rather than
deep, so it bypasses recursion check at the macro-expansion layer, but
triggers deep recursion in parser.
In the ideal world, the parser would just handle deeply nested structs
gracefully. We'll get there some day, but at the moment, let's try to be
simple, and just avoid expanding macros with unbalanced parenthesis in
the first place.

9808: fix: Look for enum variants and trait assoc functions when looking for lang items r=matklad a=Veykril
Examples for lang enum variants are the `Option` variants.
Assoc trait functions aren't being seen since they aren't declared in the direct module scope.

Fix ide_completion tests.
Move 'complete_record_literal' call to the main completion function.
Fix a rendering bug when snippet not available.
Checks if an expression is expected before adding completion for struct literal.
Move 'completion struct literal with private field' test to 'expressions.rs' test file.
Update 'expect' tests with new check in 'complete record literal'.
9764: fix: Don't use the module as the candidate node in fuzzy path flyimport r=Veykril a=Veykril
The problem was that the candidate node is whats being used for the scope, so using an inline module will yield the surrounding scope of the module instead of the scope of the module itself.
Also seems to fix the problem in this comment https://github.com/rust-analyzer/rust-analyzer/issues/9760#issuecomment-891125674, though I could not recreate that in a test for some reason.

9453: Add first-class limits. r=matklad,lnicola a=rbartlensky
Partially fixes#9286.
This introduces a new `Limits` structure which is passed as an input
to `SourceDatabase`. This makes limits accessible almost everywhere in
the code, since most places have a database in scope.
One downside of this approach is that whenever you query limits, you
essentially do an `Arc::clone` which is less than ideal.
Let me know if I missed anything, or would like me to take a different approach!

9568: feat: add 'for' postfix completion r=lnicola a=mahdi-frms

Note that, while we don't currently have a fuzzy-matching score, it
makes sense to special-case postfix templates -- it's very annoying when
`.not()` gets sorted before `.not`. We might want to move this infra to
fuzzy matching, once we have that!
Before this PR, SourceChange used a bool and CompletionItem used an enum
to signify if edit is a snippet. It makes sense to use the same pattern
in both cases. `bool` feels simpler, as there's only one consumer of
this API, and all producers are encapsulated anyway (we check the
capability at the production site).
* Keep codegen adjacent to the relevant crates.
* Remove codgen deps from xtask, speeding-up from-source installation.
This regresses the release process a bit, as it now needs to run the
tests (and, by extension, compile the code).
The completion of cfg will look at the enabled cfg keys when
performing completion.
It will also look crate features when completing a feature cfg
option. A fixed list of known values for some cfg options are
provided.
For unknown keys it will look at the enabled values for that cfg key,
which means that completion will only show enabled options for those.

9027: feat: Attribute completion is context aware r=Veykril a=Veykril
This splits off the `lint` and `derive` completions into their own submodules of `attribute`.
The idea is to create a lazy global hashmap that maps `SyntaxKind` to attribute names(`&[&str]`) in which we index with the syntax kind of the "thing" we are attributing giving us the attributes back that are valid for this kind. Then we use this name to do a binary search on the attribute list to fetch and build the corresponding completion item.

Add tab stops for all the keywords that I judged fit. I also introduced some line breaks and spaces, following the pattern I saw in the `postfix` module.
Co-authored-by: Eduardo Canellas <eduardocanellas98@gmail.com>
The problem was the skipping of binders in
`resolve_method_call_as_callable`; this still doesn't use the _correct_
substitution, but at least it doesn't return a type with free variables
in it.
Fixes#8931.
8794: Give MergeBehaviour variants better names r=Veykril a=Veykril
I never really liked the variant names I gave this enum from the beginning and then I found out about rustfmt's `imports_granularity` config:
> imports_granularity
>
> How imports should be grouped into use statements. Imports will be merged or split to the configured level of granularity.
>
> Default value: Preserve
> Possible values: Preserve, Crate, Module, Item
> Stable: No
I personally prefer using `crate` over `full` and `module` over last, they seem more descriptive. Keeping these similar between tooling also seems like a good plus point to me.
We might even wanna take over the entire enum at some point if we have a `format/cleanup imports` assists in the future which would probably want to also have the `preserve` and `item` options.

8267: Adding gifs and screenshots for features in manual r=matklad a=MozarellaMan
For #6539
This includes most of gif or screenshot examples of most items in the "Features" header. With the exceptions of:
- **On Typing Assists** - couldn't get it to work for a demo, I'm probably missing something?
- **Structural search and replace** - looked to be already a visual example of the feature
- **Workspace symbol** - wasn't sure how best to show this, all of the examples maybe? Also wasn't sure of the best code example to show it off
- **Semantic Syntax Highlighting** - seemed obvious enough to not need a screenshot, but I could easily add this
All the gifs/pngs are hosted in this [comment](https://github.com/rust-analyzer/rust-analyzer/issues/6539#issuecomment-809574840). Please let me know if any of them aren't suitable (and why) and I'll improve it! Or if you don't like the theme/font

8132: Add `'` to trigger_characters, allowing more direct lifetime completions r=Veykril a=Veykril
Fixes having to type a character after `'` to complete lifetimes and labels
Co-authored-by: Lukas Wirth <lukastw97@gmail.com>
8124: Add basic lifetime completion r=Veykril a=Veykril
This adds basic lifetime completion, basic in the sense that the completions for lifetimes are only shown when the user enters `'` followed by a char. Showing them when nothing is entered is kind of a pain, as we would want them to only show up where they are useful which in turn requires a lot of tree traversal and cursor position checking to verify whether the position is valid for a lifetime. This in itself doesn't seem too bad as usually when you know you want to write a lifetime putting `'` to ask for lifetime completions seems fine.
~~I'll take a look at whether its possible to lift the restriction of having to put a char after `'`.~~ This actually already works so I guess this is the clients responsibility, in which case VSCode doesn't like it.

7900: show function params in completion detail r=matklad a=JoshMcguigan
This resolves#7842 by updating the detail for function completions from `-> T` to `fn(T, U) -> V`. I added an expicit unit test for this, `ide_completion::render::fn_detail_includes_args_and_return_type`, which passes.
Lots of other unit tests fail (~60 of them) due to this change, although I believe the failures are purely cosmetic (they were testing the exact format of this output). I'm happy to go update those tests, but before I do that I'd like to make sure this is in fact the format we want for the detail?
edit - I realized `UPDATE_EXPECT=1 cargo test` automatically updates `expect!` tests. Big 👍 to whoever worked on that! So I'll go ahead and update all these tests soon. But I still would like to confirm `fn(T, U) -> V` is the desired content in the `detail` field.

7873: Consider unresolved qualifiers during flyimport r=matklad a=SomeoneToIgnore
Closes https://github.com/rust-analyzer/rust-analyzer/issues/7679
Takes unresolved qualifiers into account, providing better completions (or none, if the path is resolved or do not match).
Does not handle cases when both path qualifier and some trait has to be imported: there are many extra issues with those (such as overlapping imports, for instance) that will require large diffs to address.
Also does not do a fuzzy search on qualifier, that requires some adjustments in `import_map` for better queries and changes to the default replace range which also seems relatively big to include here.
