I've noticed a bunch of "main loop too long" warnings in console when
typing in Cargo.toml. Profiling showed that the culprit is `rustc
--print cfg` call.
I moved it to the background project loading phase, where it belongs.
This highlighted a problem: we generally use single `cfg`, while it
really should be per crate.
7276: Remove map module from la-arena public API r=lnicola a=arzg
It’s unlikely that more items will be added to the module, so it’s simpler for users if `ArenaMap` is re-exported and the module made private.
This doesn’t compile for the same reason that #7275 doesn’t:
> This pull request doesn’t compile because dependencies on la-arena go through crates.io, so existing dependencies on the crate are referencing an old version. As such, this PR will only compile once a new la-arena version has been published.

7110: Deduplicate macros when offering completion r=matklad a=AdnoC
Closes https://github.com/rust-analyzer/rust-analyzer/issues/7081
When iterating over the names within the `hir_def::resolver::Scope` for a module, track what macros are in the `hir_def::item_scope::ItemScope::legacy_macros` collection for the module. When iterating over names from the prelude, do not proccess the name if it had been in the `legacy_macros` collection.
This is implemented with a `FxHashSet` in the `Scope::process_names` function that is populated when iterating over `legacy_macros` and checked when iterating over the prelude.
Alternative implementation could instead query the `legacy_macros` `FxHashMap` directly when processing names in the prelude.
Also, I'd like to add a test for this, but I'm not sure where it could be added.

7224: Remove unnecessary allocation when checking whether to hide argument name hint r=jhpratt a=jhpratt
The case-insensitive prefix/suffix check can be performed

to allocate a new string. As a side effect, it's also no longer
necessary to convert the entire string to lowercase, as it's done as
needed. As the only case equality we're handling is ASCII, this
operation can be further optimized by using byte equality, rather than
character equality.

7145: Proper handling $crate Take 2 [DO NOT MERGE] r=edwin0cheng a=edwin0cheng
Similar to previous PR (#7133) , but improved the following things :
1. Instead of storing the whole `ExpansionInfo`, we store a similar but stripped version `HygieneInfo`.
2. Instread of storing the `SyntaxNode` (because every token we are interested are IDENT), we store the `TextRange` only.
3. Because of 2, we now can put it in Salsa.
4. And most important improvement: Instead of computing the whole frames every single time, we compute it recursively through salsa: (Such that in the best scenario, we only need to compute the first layer of frame)
```rust
let def_site = db.hygiene_frame(info.def.file_id);
let call_site = db.hygiene_frame(info.arg.file_id);
HygieneFrame { expansion: Some(info), local_inner, krate, call_site, def_site }
```
The overall speed compared to previous PR is much faster (65s vs 45s) :

7140: Store trait associated items in fst r=matklad a=SomeoneToIgnore
Store imported traits' associated function/methods and constants into `ImportMap.fst` and pefrorm the imports search on them.
This is a first step towards trait autoimport during completion functionality, the way I see it, after this PR, only a few major things are left to be done:
* store all traits' assoc items into fst, not only the ones in scope, as we do now. Any code pointers on how to do this are welcome 😄
* adjust a few modules in completions crate (`dot.rs`, `qualified_path.rs` at least) to query the import map, reusing the `import_assets` logic heavily
==
With the current import and autoimport implementations, it looks like for a single query, we're either interested in either associated items lookup or in all other `fst` contents lookup, but never both simultaneously.
I would rather not split `fst` in two but add another `Query` parameter to separate those, but let me know if you have any ideas.

Depends on #6587
Until that is merged, the diff is https://github.com/MarijnS95/rust-analyzer/compare/stmt..replace-expr-with-stmt
---
Now that statements can be matched and replaced (#6587) some usecases require expressions to be replaced with statements as well. This happens when something that can ambiguously be an expression or statement like `if` and loop blocks appear in the last position of a block, as trailing expression. In this case a replacement pattern of the form `if foo(){$a();}==>>$a();` will only substitute `if` blocks in the list of statements but not if they (implicitly) end up in the trailing expression, where they are not wrapped by an EXPR_STMT (but the pattern and template are, as parsing only succeeds for the `stmt ==>> stmt` case).
Instead of adding two rules that match an expression - and emit duplicate matching errors - allow the template for expressions to be a statement if it fails to parse as an expression.
---
Another gross change that does not seem to break any tests currently, but perhaps a safeguard should be added to only allow this kind of replacement in blocks by "pushing" the replacement template to the statement list and clearing the trailing expression?

6587: SSR: Support statement matching and replacing r=davidlattimore a=MarijnS95
For #3186
Hi!
This is a smaller initial patchset that came up while working on support for statement lists (and my first time working on RA 😁). It has me stuck on trailing semicolons for which I hope to receive some feedback. Matching (and replacing) `let` bindings with a trailing semicolon works fine, but trying to omit these (to make patterns more ergonomic) turns out more complex than expected.
The "optional trailing semicolon solution" implemented in this PR is ugly because `Matcher::attempt_match_token` should only consume a trailing `;` when parsing `let` bindings to prevent other code from breaking. That at the same time has a nasty side-effect of `;` ending up in the matched code: any replacements on that should include the trailing semicolon as well even if it was not in the pattern. A better example is in the tests:
3ae1649c24/crates/ssr/src/tests.rs (L178-L184)
The end result to achieve is (I guess) allowing replacement of let bindings without trailing semicolon like `let x = $a ==>> let x = 1` (but including them on both sides is still fine), and should make replacement in a macro call (where `foo!(let a = 2;)` for a `$x:stmt` is invalid syntax) possible as well. That should allow to enable/fix these tests:
3ae1649c24/crates/ssr/src/tests.rs (L201-L214)
A possible MVP of this PR might be to drop this optional `;' handling entirely and only allow an SSR pattern/template with semicolons on either side.

7115: Migrate HasSource::source to return Option r=matklad a=nick96
I've made a start on fixing #6913 based on the provided work plan, migrating `HasSource::source` to return an `Option`. The simple cases are migrated but there are a few that I'm unsure exactly how they should be handled:
- Logging the processing of functions in `AnalysisStatsCmd::run`: In verbose mode it includes the path to the module containing the function and the syntax range. I've handled this with an if-let but would it be better to blow up here with `expect`? I'm not 100% on the code paths but if we're processing a function definition then the source should exist.
I've handled `source()` in all code paths as `None` being a valid return value but are there some cases where we should just blow up? Also, all I've done is bubble up the returned `None`s, there may be some places where we can recover and still provide something.

Co-authored-by: Jesse Bakker <github@jessebakker.com>
The `LifetimeParam` and `Local` variants use `source()` to find their
range. Now that `source()` returns an `Option` we need to handle the
`None` case.
In #6901 some special case handling for proc-macros was introduced to
prevent panicing as they have no AST. Now the new HasSource::source
method is used that returns an option.
Generally this was a pretty trivial change, the only thing of much
interest is that `hir::MacroDef` now implements `TryToNav` not `ToNav`
as this allows us to handle `HasSource::source` now returning an option.
Added the error message to the doc for the UnresolvedProcMacro
diagnostic, explaining that either enabling the procMacro setting
or disabling this diagnostic should make the warnings go away.

7071: Pass --all-targets to "cargo check" when discovering external resources r=matklad a=WasabiFan
There is a repro case and background in the linked issue.
In short, the goal of this MR is to allow rust-analyzer to discover proc-macros which come from your tests (including, most importantly, dev-dependencies).
By default, `cargo check` implies the equivalent of `--lib --bins`, meaning it'll check your libraries and binaries -- but not tests! This means proc-macros (or, I guess, build scripts as well) weren't discovered by rust-analyzer if they came from tests.
One solution would be to manually add `--lib --bins --tests` (i.e., just augment the effective options to include tests). However, in this MR, I threw in `--all-targets`, which [according to the docs](https://doc.rust-lang.org/cargo/commands/cargo-check.html#target-selection) implies `--benches --examples` too. I have absolutely no idea what repercussions that will have on rust-analyzer for other projects, nor do I know if it's a problem that build scripts will now be discovered for tests/examples/benches. But I am not aware of a reason you _wouldn't_ want to discover these things in your examples too.
I think the main drawback of this change is that it will likely slow down the `cargo check`. At a minimum, it'll now be checking your tests _and_ their dependencies. The `cargo check` docs also say that including `--tests` as I have here may cause your lib crate to be built _twice_, once for the normal target and again for unit tests. My reading of that caveat suggests that "building twice" means it's built once for the tests _inside_ your lib, with a test profile, and again for any consumers of your lib, now using a normal release profile or similar. This doesn't seem surprising.
Very minor caveat: `--tests` will not include tests within a binary if it has `test = false` set in `Cargo.toml`. (I discovered this manually by trial-and-error, but hey, it actually says that in the docs!) This is likely not an issue, but _does_ mean that if you are -- for whatever reason -- disabling tests like that and then manually specifying `cargo test --package <...> --bin <...>` to run them, rust-analyzer will remain unaware of proc-macros in your tests.
I have confirmed this fixes the original issue in my sandbox example linked in #7034 and in my own project in which I originally discovered this. I've left it configured as my default RA language server and will report back if I notice any unexpected side-effects.

A follow-up of https://github.com/rust-analyzer/rust-analyzer/pull/6918#issuecomment-748511151 and the PR itself.
Tweaks the `import_map` query api to be more flexible with the ways to match against the import path and now fuzzy imports search in names only.
This had improved the completion speed for me locally in ~5 times for `fuzzy_completion` span time, but please recheck me here.
IMO we're fast and presice enough now, so I've added the modules back to the fuzzy search output.
Also tweaks the the expect tests to display functions explicitly, to avoid confusing "duplicate" results.

Avoid mutation of snapshot's config -- that's spooky action at a
distance. Instead, copy it over to a local variable.
This points out a minor architecture problem, which we won't fix right
away.
Various `ide`-level config structs, like `AssistConfig`, are geared
towards one-shot use when calling a specific methods. On the other
hand, the large `Config` struct in `rust-analyzer` is a long-term
config store.
The fact that `Config` stores `AssistConfig` is accidental -- a better
design would probably be to just store `ConfigData` inside `Config`
and create various `Config`s on the fly out of it.

I'm not sure if this is totally correct, it looks like we create **two** `EagerCallLoc`s per macro invocation, one for the arguments (?), and one for the actual macro call. I gave both the same `AstId`, hopefully that's correct.

6964: Add full pattern completions for Struct and Variant patterns r=matklad a=Veykril
Just gonna call it full pattern completion as pattern completion is already implemented in a sense by showing idents in pattern position. What this does is basically complete struct and variant patterns where applicable(function params, let statements and refutable pattern locations).
This does not replace just completing the corresponding idents of the structs and variants, instead two completions are shown for these, a completion for the ident itself and a completion for the pattern(if the pattern make sense to be used that is). I figured in some cases one would rather type out the pattern manually if it has a lot of fields but you only care about one since this completion would cause one more work in the end since you would have to delete all the extra matched fields again.
These completions are tagged as `CompletionKind::Snippet`, not sure if that is the right one here.

Since we just tried running `rustup component add`, it doesn't make sense to me
to recommend trying that again. If we're reaching this case, it's probably more
likely that rustc was installed via package manager, in which case the source
should be installed the same way (e.g. if you install the rust-src package on
Ubuntu it will install a symlink in the right place to make our sysroot
detection work).

[`hir_ty::utils::Generics`](https://github.com/rust-analyzer/rust-analyzer/blob/master/crates/hir_ty/src/utils.rs#L153) currently only assumes type parameters but not lifetime parameters and therefor creates incorrect index and length calculations, this PR just makes the use sites ignore LifetimeGenerics for now.

6750: Remove documentation query, move doc handling to attributes r=matklad a=Veykril
Fixes#3182
Removes the documentation query in favor of `Attrs::docs`. Attrs already handlded doc comments partially but the alloc saving check was wrong so it only worked when other attributes existed as well. Unfortunately the `new` constructor has to do an intermediate allocation now because we need to keep the order of mixed doc attributes and doc comments.
I've also partially adjusted the `hover` module to have its tests check the changes, it still has some `HasSource` trait usage due to the `ShortLabel` trait usage, as that is only implemented on the Ast parts and not the Hir, should this ideally be implemented for the Hir types as well?(would be a follow up PR of course)

```rust

_ => (),

into the corresponding
```rust
if let pat = foo {
expr
}
```
which is the main reasoning behind this.
I put this into the same file as `replace_if_let_with_match` because the are complementing each other and I would probably rename the file to something like `replace_if_let_match` but I didn't do that for now because I was unsure whether git would still view this as a rename or not due to the amount of changes in the file so that the diff is still properly visible for now.

6645: Publish diagnostics for macro expansion errors r=matklad a=jonas-schievink
This adds 2 new diagnostics, emitted during name resolution:
* `unresolved-proc-macro`, a weak warning that is emitted when a proc macro is supposed to be expanded, but was not provided by the build system. This usually means that proc macro support is turned off, but may also indicate setup issues when using rust-project.json. Being a weak warning, this should help set expectations when users see it, while not being too obstructive. We do not yet emit this for attribute macros though, just custom derives and `!` macros.
* `macro-error`, which is emitted when any macro (procedural or `macro_rules!`) fails to expand due to some error. This is an error-level diagnostic, but currently still marked as experimental, because there might be spurious errors and this hasn't been tested too well.
This does not yet emit diagnostics when expansion in item bodies fails, just for module-level macros.
Known bug: The "proc macro not found" diagnostic points at the whole item for custom derives, it should just point at the macro's name in the `#[derive]` list, but I haven't found an easy way to do that.

6553: Auto imports in completion r=matklad a=SomeoneToIgnore
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.

6524: Add support for loading rustc private crates r=matklad a=xldenis
This PR presents a solution to the problem of making`rustc_private` crates visible to `rust-analyzer`.
Currently developers add dependencies to those crates behind a `cfg(NOT_A_TARGET)` target to prevent `cargo` from building them.
This solution is unsatisfactory since it requires modifying `Cargo.toml` and causes problems for collaboration or CI.
The proposed solution suggested by @matklad is to allow users to give RA a path where the `rustc` sources could be found and then load that like a normal workspace.
This PR implements this solution by adding a `rustcSource` configuration item and adding the cargo metadata to the crate graph if it is provided.
------
I have no idea how this should be tested, or if this code is generally tested at all. I've locally run the extension with these changes and it correctly loads the relevant crates on a `rustc_private` project of mine.

Adds static semantic token modifier to associated functions, resolves#6194
## Info
- Associated functions are more-or-less equivalent to static methods in other languages. This PR checks, for each function, whether that function has a self_param, and whether it's enclosed in a trait/impl.
## Changes
- Added method ```is_associated``` to code_model::Function. This basically gets the source from the ast, and checks whether the enclosing scope is an impl or trait.
- Added `static` to HighlightModifiers
- Added unit test
## Tests
- Ran ```cargo test```
