improve the default constructor mode when filling fields
Instead of filling a boolean field with `bool::default()` it's not `false` and same for `Option` instead of using `Option::default()` it will be `None`
Collect obligations from RPITs (Return Position `impl Trait`) of a function which is being inferred.
This allows inferring {unknown}s from RPIT bounds.
fix: handle raw identifiers in move_module_to_file
Fixes#12045
Note that I special case'd mod named `r#mod` as commented in the code. Although it's very unlikely that one would use such name, I included it in this fix for the sake of completeness.
fix: Spawn a new thread with a larger stack for the LSP and proc-macro server
This runs the server and proc-macro process in dedicated threads with 8 MB of stack space to paper over OS differences and fix occasional stack overflows.
This hopefully resolves https://github.com/rust-lang/rust-analyzer/issues/11669
internal: Add a `NameContext` to `CompletionContext`, move out some ImmediateLocation variants
Continues the completion rewrite I started some time ago
(will merge tomorrow after stable since our completion tests still let a lot through)
fix: support `associated_const_equality` in parser
This pr fixes#11965. The parser now allows eq constraints on associated constants.
I've added tests for `HasCount<Count = {N}>` and `HasCount<Count = 0>`
feat: Add trailing `;` when typing `=` in assignment
This does have a false positive to keep in mind, it will add a trailing `;` in the following snippet too, which is probably not desired:
```rust
fn is_zero(i: i32) -> bool {
i $0 0
}
```
However, that function is unlikely to be written from the "inside out" like that, so it might be acceptable. Typically `=` is only inserted last when the author realizes that an existing expression should be assigned to some variable.
feat: allow customizing the command for running build scripts
I have tested this locally and it fixed#9201 with some small changes on the compiler side with suggestions from https://github.com/rust-analyzer/rust-analyzer/issues/9201#issuecomment-1019554086.
I have also added an environment variable `IS_RA_BUILDSCRIPT_CHECK` for crates to detect that it is a check for buildscripts, and allows defaulting to bogus values for expected environment variables.
11883: fix(ide): move moudle directory when rename r=rainy-me a=rainy-me
fix: #10992
Added `FileSystemEdit::MoveDir` variant for move dirs. Original implemented as recursively move child mod files but had many issues like
1. left empty dir after rename file
2. only affect rust file
3. not performant
so changed to current version

11964: internal: Show more project building errors to the user r=Veykril a=Veykril
Something very fishy is going on with the `rustc_workspace` handling, which caused this bug to only manifest in the `std` library but not other library crate... So there is either a bug there or just the fact that we seem to add duplicate dependencies (I think this is what we are doing with this right?) might be tripping something up somewhere.

Close#11944
Co-authored-by: iDawer <ilnur.iskhakov.oss@outlook.com>
- `T: ~const Drop` has a special meaning in Rust 1.61 that we don't implement.
(So ideally, we'd only ignore `~const Drop`, but this should be fine
for now.)
- `Destruct` impls are built-in in 1.62 (current nightlies as of 08-04-2022), so until
the builtin impls are supported by Chalk, we ignore them as well.
Since `Destruct` is implemented for everything in non-const contexts
IIUC, this should also work fine.
Fixes#11932.
11920: Consider types of const generics r=flodiebold a=HKalbasi
fix#11913
We should emit type_mismatch in const generics, probably after #7434. Currently they will lead to a misleading, time of use type error (like the added test).

While we don't support const args in type inference yet, we can at least
make use of the fallback path resolution to resolve paths in const args
in the IDE layer to enable some features for them.
11905: internal: Remove hir_expand macro recursion check r=jonas-schievink a=jonas-schievink
This check is insufficient to ensure finite macro nesting, and so all callers already have their own recursion limit, which makes this check redundant.

Originally, this check was added in https://github.com/rust-analyzer/rust-analyzer/pull/3671

11891: Better error message on Flycheck Error message (from: unactionable error message if we are using `clippy` as the checker) r=Veykril a=flipbit03
I have commented on this [S-unactionable issue](https://github.com/rust-analyzer/rust-analyzer/issues/6589) that the Flycheck error message should maybe provide a hint about what tool it actually runs. Searching on some places on the Internet I've found multiple people, including myself, losing copious amounts of time on the same issue. So I've decided to make this very small PR :-)
From an user experience standpoint, the current error message is unhelpful to the end user, because the end user does not know exactly what it needs to check/fix (outdated, broken, or missing `cargo clippy`). In my own case, `cargo clippy` was actually missing altogether (developing off `rust:1.59.0-bullseye` official Docker image).
Thanks in advance!

11894: complete pattern args based on type name r=Veykril a=cameron1024
Addresses #11892
Changes function argument completion to cover a case like this:
```rust
struct Foo { bar: i32 }
fn qux(Foo { bar }: Foo) {
println!("{bar}");
}
```
When completing the function call for `qux`, instead of expanding to `qux(_)`, it will now expand to `qux(foo)` (based on the snake-cased version of the name of the ADT)
Non ADTs are unaffected

11865: Fix: Select correct insert position for disabled group import r=jonasbb a=jonasbb
The logic for importing with and without `group_imports` differed
significantly when no previous group existed. This lead to the problem
of using the wrong position when importing inside a module (#11585) or
when inner attributes are involved.
The existing code for grouped imports is better and takes these things
into account.
This PR changes the flow to use the pre-existing code for adding a new
import group even for the non-grouped import settings.
Some coverage markers are updated and the `group` is removed, since they
are now invoked in both cases (grouping and no grouping).
Tests are updated and two tests (empty module and inner attribute) are
added.

11699: feat: assist to remove unneeded `async`s r=Ethiraric a=Ethiraric
This should fix#11392
This PR adds a quickfix on functions marked with `async` that suggests, if and only if no `await` expression in find in the body of the function (it relies on `SyntaxNode::descendants()` to recursively traverse blocks), to remove the `async` keyword.
The lint is made so that it triggers only if the cursor is not in the body of the function, so that it does not pollute the quickfix list.
It does not trigger a diagnostic. I don't know if this repository is the place to implement those (`clippy`?). If it is, I would very much like pointers on where to start looking.
If there are test cases I haven't thought about, please do suggest.

10802: Allow clients to configure the global workspace search limit r=Veykril a=knutwalker
Playing around with [helix](https://helix-editor.com) I realized that the global worksapce symbol search works different compared to vs-code.
Helix requires all possible symbols in one query and does no subsequent refinement searched.
This PR adds a configuration option to override the default search limit with the default being the currently hardocded value.
Helix users can increment this limit for their instance with a config like
```toml
[[language]]
name = "rust"
language-server = { command = "rust-analyzer" }
[language.config]
workspace = { symbol = { search = { limit = 65536 }}}
```
Other editors are not affected by this change.

11866: fix: Prevent underflow in range conversion r=Veykril a=skyfmmf
Previously, when line numbers of Rust spans were converted to LSP ranges, they could underflow resulting in very large line numbers. As an underflow is always wrong, prevent it and use 0 instead.
This was noticed when opening an empty file in `src/bin/` of a library crate. In this case rustc produces a span with `"line_start": 0, "line_end": 0` resulting in the underflow.

11879: Suggest infered type in auto complete r=HKalbasi a=HKalbasi
fix#11855
It doesn't work for return types and consts (so their tests are failing) because I can't find their body node in the original file. (Are these original and fake file documented somewhere?)
Also it currently needs to type first character of the type (or manual ctrl+space) to open the auto complete panel, is it possible to open it automatically on typing `:` and `->`?

TIL that Chalk expects the arguments to a generic associated type to come *before* the ones for the parent trait, not *after* as we have been doing with all other nested generics. Fixing this requires a larger refactoring, so for now this just papers over the problem by completely ignoring parameters of associated types.
