6350: Make IncorrectDiagnostic match rustc by copying rustc's code. r=popzxc a=ArifRoktim
This closes#6343 and closes#6345.
The old algorithm which used a `DetectedCase` enum, didn't match how rustc thinks of cases. Some inputs can be interpreted as more than 1 case depending on the situation. For example, to rustc:
- `ABCD`: Can be both camel case and upper snake case
- `X86_64`: Can be both camel case and upper snake case
I could've made `detect_case` return a collection of `DetectedCase` and then modified the other code as such, but I think using the same code rustc uses is simpler and a surefire way to achieve the same diagnostics as rustc.

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)
```

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).
The proper fix I think is:
* move rust-lang/rust library crates to a separate workspace
* when packaging rust-src component, vendor sources of external deps
This errro specifically:

6220: implement binary operator overloading type inference r=flodiebold a=ruabmbua
Extend type inference of *binary operator expression*, by adding support for operator overloads.
Before this merge request, the type inference of binary expressions could only resolve operations done on built-in primitive types. This merge requests adds a code path, which is executed in case the built-in inference could not get any results. It resolves the proper operator overload trait in *core::ops* via lang items, and then resolves the associated *Output* type.
```rust
struct V2([f32; 2]);
#[lang = "add"]
pub trait Add<Rhs = Self> {
/// The resulting type after applying the `+` operator.
type Output;
/// Performs the `+` operation.
#[must_use]
fn add(self, rhs: Rhs) -> Self::Output;
}
impl Add<V2> for V2 {
type Output = V2;
fn add(self, rhs: V2) -> V2 {
let x = self.0[0] + rhs.0[0];
let y = self.0[1] + rhs.0[1];
V2([x, y])
}
}
fn test() {
let va = V2([0.0, 1.0]);
let vb = V2([0.0, 1.0]);
let r = va + vb; // This infers to V2 now
}
```
There is a problem with operator overloads, which do not explicitly set the *Rhs* type parameter in the respective impl block.
**Example:**
```rust
impl Add for V2 {
type Output = V2;
fn add(self, rhs: V2) -> V2 {
let x = self.0[0] + rhs.0[0];
let y = self.0[1] + rhs.0[1];
V2([x, y])
}
}
```
In this case, the trait solver does not realize, that the *Rhs* type parameter is actually self in the context of the impl block. This stops type inference in its tracks, and it can not resolve the associated *Output* type.
I guess we can still merge this back, because it increases the amount of resolved types, and does not regress anything (in the tests).

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.

P.S. My eyes were bleeding when I had to write the code for the example...

6153: Improve prime_caches and display its progress r=matklad a=jonas-schievink
It now computes the `CrateDefMap` of all crates, which is generally a reasonable approximation for "IDE features ready". There is still some delay after this finishes, I suspect mostly due to impl collection, which takes a while, but this should be an improvement already.
For more accurate progress reports, this topologically sorts all crates before starting this operation. ~~Because that is also the ordering in which parallelization makes sense (which was previously attempted in https://github.com/rust-analyzer/rust-analyzer/pull/3529), I decided to throw that into the mix as well. It still doesn't provide *that* much of a performance boost, but it does scale beyond the current single-core architecture, and adding it was very easy.~~
~~Unfortunately, as written, this will not tell the user which crate is actually causing slowdowns, since the displayed crate is the last one that was *started*, not the one we are currently *blocked* on, but that seems fairly difficult to implement unless I'm missing something.~~
(I have removed rayon for now since it does not work correctly with cancellation.)

6158: Fix for negative literals in macros r=matklad a=cutsoy
_This pull request fixes #6028._
When writing `-42.0f32` in Rust, it is usually parsed as two different tokens (a minus operator and a float literal).
But a procedural macro can also generate new tokens, including negative [float literals](https://doc.rust-lang.org/stable/proc_macro/struct.Literal.html#method.f32_suffixed):
```rust
#[proc_macro]
fn example_verbose(input: TokenStream) -> TokenStream {
let literal = Literal::f32_suffixed(-42.0);
quote! { #literal }
}
```
or even shorter
```rust
#[proc_macro]
fn example(input: TokenStream) -> TokenStream {
let literal = -42.0f32;
quote! { #literal }
}
```
Unfortunately, these currently cause RA to crash:
```
thread '<unnamed>' panicked at 'Fail to convert given literal Literal {
text: "-42.0f32",
id: TokenId(
4294967295,
),
}', crates/mbe/src/subtree_source.rs:161:28
```
This pull request contains both a fix 8cf9362 and a unit test 27798ee. In addition, I installed the patched server with `cargo xtask install --server` and verified in VSCode that it no longer crashes when a procedural macro returns a negative number literal.

5954: Add flexible configuration for runnables r=popzxc a=popzxc
This PR introduces two new configuration options for runnables: `overrideCargo` and `cargoExtraArgs`.
These options are applied to all the "run" tasks of rust analyzer, such as binaries and tests.
Overall motivation is that rust-analyzer provides similar options, for example, for `rustfmt`, but not for runnables.
## `overrideCargo`
This option allows user to replace `cargo` command with something else (well, something that is compatible with the cargo arguments).
Motivation is that some projects may have wrappers around cargo (or even whole alternatives to cargo), which do something related to the project, and only then run `cargo`. With this feature, such users will be able to use lens and run tests directly from the IDE rather than from terminal.
## `cargoExtraArgs`
This option allows user to add any additional arguments for `cargo`, such as `--release`.
It may be useful, for example, if project has big integration tests which take too long in debug mode, or if any other `cargo` flag has to be passed.

6033: Make name resolution resolve proc macros instead of relying purely on the build system r=matklad a=jonas-schievink
This makes name resolution look at proc-macro declaration attributes like `#[proc_macro_derive]` and defines the right proc macro in the macro namespace, fixing unresolved custom derives like `thiserror::Error` (which can cause false positives, now that we emit diagnostics for unresolved imports).
This works even when proc-macro support is turned off, in which case we fall back to a dummy expander that always returns an error. IMO this is the right way to handle at least the name resolution part of proc. macros, while the *expansion* itself should rely on the build system to build and provide the macro DLL. It does mean that they may go out of sync, but we can provide diagnostics if that happens (something like "could not find macro X in crate Y – ensure that all files of crate Y are saved").
I think it is valuable to be able to reason about proc macros even when we can't expand them, since proc macro expansion can break between Rust releases or users might not want to turn it on for performance reasons. It allows us to provide better diagnostics on any proc macro invocation we're not expanding (like a weak warning that informs the user that proc macro support is turned off, or that it has been disabled because the server crashed).

6073: Dont unnecessarily unnest imports r=matklad a=Veykril
Fixes#6071
This has the side effect that paths that refer to items inside of the current module get prefixed with `self`. Changing this behavior is unfortunately not straightforward should it be unwanted, though I don't see a problem with this as prefixing imports like this with `self` is what I do personally anyways 😅. You can see what I mean with this in one of the tests which had to be changed in `crates/ssr/src/tests.rs`.
There is one test that i still have to look at though, ~~which I by accident pushed with `#[ignore]` on it~~, which is `different_crate_renamed`, for some reason this now doesn't use the crate alias. This also makes me believe that aliases in general will break with this. So maybe this is not as straight forwards as I'd hoped for, but I don't really know how aliases work here.
Edit: The failing test should work now

When completing a function call, if there is an argument taken as a ref or mut ref which matches the name and type of a variable in scope, we will insert a `&` or `&mut` when filling in the function arguments. This addresses https://github.com/rust-analyzer/rust-analyzer/issues/5449.
E.g.
```rust
fn foo(x: &i32) {}
fn main() {
let x = 5;
foo # completing foo here generates `foo(&x)` now instead of `foo(x)`
}
```

6043: Allow missing trait members assist without needing braces r=matklad a=M-J-Hooper
Assist to complete missing items when implementing a trait does not appear without impl def braces (see #5144 ).
The reason behind this was that this assist is based on `ast::AssocItemList` which only appears in the AST after the braces are added to the impl def.
Instead of relying on and replacing the item list, we now instead replace the entire `ast::Impl` and add the item list if its missing.

6018: Correct project_root path for ProjectJson. r=jonas-schievink a=woody77
It was already the folder containing the rust-project.json file, not the file itself. This also removes the Option-ness of it, since it's now an infallible operation to set the member value.

6017: Don't return any TextEdit if formatting is unchanged r=jonas-schievink a=cuviper
I found that `textDocument/formatting` was always returning a full
`TextEdit` replacement, even when there are no changes, which caused Vim
(w/ vim-lsp) to always indicate a modified buffer after formatting. We
can easily compare whether there were changes and return `null` if not,
so the client knows there's nothing to do.

6016: Emit diagnostics for unresolved imports and extern crates r=jonas-schievink a=jonas-schievink
AFAIK, we don't have any major bugs in name resolution that would cause a lot of false positives here (except procedural attribute macro support and some rare issues around `#[path]` on module files), so these are *not* marked as experimental diagnostics right now.
I noticed that diagnostics in a file sometimes don't get displayed after opening, but require some edit to be performed. This seems like a preexisting issue though.
