fix: Resolve included files to their calling modules in IDE layer
Fixes https://github.com/rust-lang/rust-analyzer/issues/17390 at the expense of reporting duplicate diagnostics for modules that have includes in them when both the calling and called file are included.
internal: Reply to requests with defaults when vfs is still loading
There is no reason for us to hit the database with queries when we certainly haven't reached a stable state yet. Instead we just reply with default request results until we are in a state where we can do meaningful work. This should save us from wasting resources while starting up at worst, and at best save us from creating query and interning entries that are non-meaningful which ultimately just end up wasting memory.
internal: Optimize the usage of channel senders
Used `Sender` directly instead of a boxed closure. There is no need to use the boxed closure. This also allows the caller to decide to do something other than `unwrap` (not a fan of it BTW).
Reuse recursion limit as expansion limit
A configurable recursion limit was introduced by looking at the recursion_limit crate attribute. Instead of relying on a global constant we will reuse this value for expansion limit as well.

feat: Implement TAIT and fix ATPIT a bit
Closes#16296 (Commented on the issue)
In #16852, I implemented ATPIT, but as I didn't discern ATPIT and other non-assoc TAIT, I guess that it has been working for some TAITs.
As the definining usage of TAIT requires it should be appear in the Def body's type(const blocks' type annotations or functions' signatures), this can be done in simlilar way with ATPIT
And this PR also corrects some defining-usage resolution for ATPIT

Include vendored crates in StaticIndex
`StaticIndex::compute` filters out modules from libraries. This makes an exceptions for vendored libraries, ie libraries actually defined inside the workspace being indexed.
This aims to solve https://bugzilla.mozilla.org/show_bug.cgi?id=1846041 In general StaticIndex is meant for code browsers, which likely want to index all visible source files.
fix: tyck for non-ADT types when searching refs for `Self` kw
See e0276dc5dd (r1389848845)
For ADTs, to handle `{error}` in generic args, we should to convert them to ADT for comparisons; for others, we can directly compare the types.

With the lack of a README on the individually published library crates and the somewhat cryptic `ra_ap_` prefix it is hard to figure out where those crates belong to, so mentioning "rust-analyzer" feels like auseful hint there.
internal: Load VFS config changes in parallel
Simple attempt to make some progress f or https://github.com/rust-lang/rust-analyzer/issues/17373
No clue if those atomic orderings are right, though I don't think they are really too relevant either.
A more complete fix would probably need to replace our `ProjectFolders` handling a bit.
fix: remove AbsPath requirement from linkedProjects
Should (fingers crossed!) fix https://github.com/rust-lang/rust-analyzer/issues/17664. I opened the `rustc` workspace with the [suggested configuration](e552c168c7/src/etc/rust_analyzer_settings.json) and I was able to successfully open some rustc crates (`rustc_incremental`) and have IDE functionality.
`@Veykril:` can you try these changes and let me know if it fixed rustc?
feat: Introduce workspace `rust-analyzer.toml`s
In order to globally configure a project it was, prior to this PR, possible to have a `ratoml` at the root path of a project. This is not the case anymore. Instead we now let ratoml files that are placed at the root of any workspace have a new scope called `workspace`. Although there is not a difference between a `workspace` scope and and a `global` scope, future PRs will change that.
feat: Use spans for builtin and declarative macro expansion errors
This should generally improve some error reporting for macro expansion errors. Especially for `compile_error!` within proc-macros
feat(ide-completion): explictly show `async` keyword on `impl trait` methods

This is an preparation for https://github.com/rust-lang/rust-analyzer/issues/17719.
```rust
use std::future::Future;
trait DesugaredAsyncTrait {
fn foo(&self) -> impl Future<Output = usize> + Send;
fn bar(&self) -> impl Future<Output = usize> + Send;
}
struct Foo;
impl DesugaredAsyncTrait for Foo {
fn foo(&self) -> impl Future<Output = usize> + Send {
async { 1 }
}
//
async fn bar(&self) -> usize {
1
}
}
fn main() {
let fut = Foo.bar();
fn _assert_send<T: Send>(_: T) {}
_assert_send(fut);
}
```
If we don't distinguish `async` or not. It would be confusing to generate sugared version `async fn foo ....` and original form `fn foo` for `async fn in trait` that is defined in desugar form.
fix: let glob imports override other globs' visibility
Follow up to #14930Fixes#11858Fixes#14902Fixes#17704
I haven't reworked the code here at all - I don't feel confident in the codebase to do so - just rebased it onto the current main branch and fixed conflicts.
I'm not _entirely_ sure I understand the structure of the `check` function in `crates/hir-def/src/nameres` tests. I think the change to the test expectation from #14930 is correct, marking the `crate::reexport::inner` imports with `i`, and I understand it to mean there's a specific token in the import that we can match it to (in this case, `Trait`, `function` and `makro` of `pub use crate::defs::{Trait, function, makro};` respectively), but I had some trouble understanding the meaning of the different parts of `PerNs` to be sure.
Does this make sense?
I tested building and using RA locally with `cargo xtask install` and after this change the documentation for `arrow_array::ArrowPrimitiveType` seems to be picked up correctly!
And that is due to a case where we have two ratomls in a source root, one of which
is a `workspace_ratoml` and the other one is simple old ratoml. Since we are not checking to see if
the source root is already populated with workspace ratoml, this test fails. Due to principles of clear
code I believe it is reasonable to not have two HashMaps that are almost for the exact same thing.
So next commit should remove `workspace_ratoml` and merge it with `krate_ratoml`s.
The issue occurs because in some configurations of traits where one of them has Deref as a supertrait, RA's type inference algorithm fails to resolve the Deref::Target type, and instead uses a TyKind::BoundVar (i.e. an unknown type). This "autoderefed" type then incorrectly acts as if it implements all traits in scope.
The fix is to re-apply the same sanity-check that is done in iterate_method_candidates_with_autoref(), that is: don't try to resolve methods on unknown types. This same sanity-check is now done on each autoderefed type for which trait methods are about to be checked. If the autoderefed type is unknown, then the iterating of the trait methods for that type is skipped.
Includes a unit test that only passes after applying the fixes in this commit.
Includes a change to the assertion count in test syntax_highlighting::tests::benchmark_syntax_highlighting_parser as suggested by Lukas Wirth during review.
Includes a change to the sanity-check code as suggested by Florian Diebold during review.
feat: add preliminary support for `+ use<..>` `precise_capturing` syntax
## Summary
This PR adds basic support for the following syntax.
```rs
fn captures<'a: 'a, 'b: 'b, T>() -> impl Sized + use<'b, T> {}
// ~~~~~~~~~~~~~~~~~~~~~~~
// This opaque type does not capture `'a`.
fn outlives<'o, T: 'o>(_: T) {}
fn caller<'o, 'a, 'b: 'o, T: 'o>() {
// ~~
// ^ Note that we don't need `'a: 'o`.
outlives::<'o>(captures::<'a, 'b, T>());
}
```

internal: add more output to the status command
Bit of a lazy change, but this is was pretty handy. I think I should clean up the configuration into something a bit more legible (maybe serialize as JSON?), but I think this is a good enough starting point that we might as well start asking people for it in issue reports.
Add method `Impl::all_in_module(…)` for allowing more localized querying
This PR is motivated by an [outside use](https://github.com/regexident/cargo-modules) of the `ra_ap_hir` crate that would benefit from being able to more efficiently query for all impls of a given module (instead of having to query for its parent crate's impls and then filtering on `impl_hir.module(db) == module_hir`).
I have the suspicion that the code as is won't quite work for file-level modules, since those don't have a block, afaict, but with all the crate-rename and version shenanigans around the `ra_ap_` release process I haven't yet been able to figure out how to patch a `ra_ap_` dependency from a third-party crate (let alone how to test this from inside of `rust-analyzer`), so haven't been able to actually run and test this. 😔
Any hints on how to make this (i.e. the code itself, as well as the testing) work are more than welcome!
