In https://youtu.be/qvIZZf5dmTE, we've noticed that AstIdMap does a
linear lookup when going from SyntaxNode to Id. This leads to
accidentally quadratic overall performance. Replace linear lookup with a
O(1) hashmap lookup.
Future work: don't duplicate `SyntaxNodePtr` in `AstIdMap` and switch to
"call site dependency injection" style storage (eg, store a
`HashSet<ErasedFileAstId>`).

10902: Handle multiple cargo check quick fix spans r=Veykril a=brandondong
Resolves https://github.com/rust-analyzer/rust-analyzer/issues/10705.
**Cause:**
- For a cargo check diagnostic with multiple spans, only a single quick fix action would be created at the location of `spans[0]`. Additionally, the hover window details would only show the location of `spans[0]` next to the message.
**Fix:**
- Allow cargo check quick fix actions to be triggerable from multiple selection ranges. Specifically, if the selection intersects with any of the replacement spans, the quick fix action is shown.
- No change in behavior for the hover window details. It's pretty minor and I think showing multiple locations next to the message may be more confusing anyways.

10891: fix: emit trait names in moniker identifier r=Veykril a=tjdevries
Hi,
Not sure if this is the best fix for the problem, but I noticed that functions that part of a trait are not namespaced with the trait name, so this could lead to problems if you had a function and a trait-function both defined in the same module.
Thanks!

10872: ide_db: build symbol index from crate def map r=Veykril a=jhgg
fixes#4842, #10764
Is this looking correct? 👀
- [x] build the symbol index based upon the CrateDefMap for the given crate in `crate_symbols`
- [x] make it multi threaded again, and figure out how to cache each moduleid's symbol index in salsa.
- [x] NavigationTarget for names in macros is wrong, need to figure out how to compute a text range in the original file id?
- [x] cleanup some duped code
- [x] collect macros from `ItemScope.declared_macros()` into symbol index.
- [x] store declared macros in `ItemScope` so we can figure out where macros were defined for the index.
- [x] do something about `SymbolIndex::for_files` - ideally it should use the new module symbol index stuff.
- [x] delete `source_file_to_file_symbols` & co...
- [x] figure out what to do about `library_symbols`
- [x] maybe... speed up the new `library_symbols` - the new impl is probably much slower, and definitely much less parallel. **deciding to do nothing here, we can optimize later if necerssary.**
- [x] fix failing test: `navigation_target::tests::test_nav_for_symbol` - notably the crate def map doesn't seem to find declarations inside function.
- [x] now a bunch of other tests are failing around auto_import & qualify_path handlers. :(
- [x] need to assoc items in traits and impls

10824: project_model: print full cargo command if cargo metadata fails to run r=Veykril a=jhgg
well, `Command` implements a sensible `Debug` which *roughly* does what we want to do. Unfortunately it's got a bit of a quote situation,
So it'd output something like `"cargo" "metadata" "--format-version" "1" "--features" "foo,bar,baz"`.
Which although is a bit verbose with the quotes, it's at the very least, not entirely incorrect/misleading.

10809: fix: don't discard formatting of `use` lines r=Veykril a=iDawer
Use mutable syntax trees in `merge_imports`, `split_imports`. This tries to resolve#9013. But I haven't much managed to simplify code of merging.
Also resolve#9361. It reuses a use tree under the cursor so that comments+indentation are preserved. Merged trees are just appended to the end.
This touches bunch of tests. I removed the sorting of use trees as it needs a proper implementation that takes into account comments and line wrapping. I think it is rustfmt's job or at least until we get a close implementation.

10810: feat: Add toggle to disable cache priming r=jonas-schievink a=lnicola
Even if it doesn't prevent the rest of the features from working, cache priming tends to be quite CPU-intensive and can make people think that the load times are worse than they actually are.
It's also less useful in Code and `rust-tools` because the inlay hints and semantic highlighting trigger quite a bit of computation assuming you have a file open in the editor.

10798: ide: show go to for function hover return type r=Veykril a=jhgg
I've found myself wanting this... adds to the hover quick go-to for a function's return type:
This is particularly useful when you are hovering over a function in a long chain, like:
```rust
foo.bar().b$0az().some_trait_fn();
```
where `baz`'s return type is not immediately obvious, but the chain is not long enough to trigger chain inlay hints...
i guess I could just select `foo.bar().baz()` too to get the types too...

10769: Add proc macro ABI for rustc 1.58 r=lnicola a=alexjg
This fixes#10766.
I do have some concerns here. The proc macro server API has added three methods to `TokenStream` which I don't really know how to implement in `RustcServer`. Namely `expand_expr`, `before`, and `after`. You'll see that these are currently `unimplemented!` in `crates/proc_macro_server/src/abis/abi_1_58/rustc_server.rs`. I don't have the expertise to fill in the blanks here, it may be necessary to pull in someone who knows a bit more about the proc macro crate.
I think this will only be a problem when actually attempting to expand a macro, so this is probably strictly better than not including the updated ABI at all.

Revert "Fix `impl_trait` function to emit correct ast"
This reverts commit 55a4813151.
Fix `impl_def_from_trait`
It now generates the correct `ast::Impl` using
`generate_trait_impl_text` and parses it to form the right node (copied
from the private fn 'make::ast_from_text').
Cargo will always output something on success:
```
$ cargo check --message-format=json
{"reason":"compiler-artifact", ... snipped ... }
{"reason":"build-finished","success":true}
```
However, rustc does not output anything on success:
```
$ rustc --error-format=json main.rs
$ echo $?
0
```
Restore the behaviour prior to #10517, where an exit code of 0 is
considered good even if nothing is written to stdout.
This enables custom overrideCommand values that use rustc rather than
cargo.
10689: Handle pub tuple fields in tuple structs r=Veykril a=adamrk
The current implementation will throw a parser error for tuple structs
that contain a pub tuple field. For example,
```rust
struct Foo(pub (u32, u32));
```
is valid Rust, but rust-analyzer will throw a parser error. This is
because the parens after `pub` is treated as a visibility context.
Allowing a tuple type to follow `pub` in the special case when we are
defining fields in a tuple struct can fix the issue.
I guess this is a really minor case because there's not much reason
for having a tuple type within a struct tuple, but it is valid rust syntax...

10623: internal: replace L_DOLLAR/R_DOLLAR with parenthesis hack r=matklad a=matklad
The general problem we are dealing with here is this:
```
macro_rules! thrice {
($e:expr) => { $e * 3}
}
fn main() {
let x = thrice!(1 + 2);
}
```
we really want this to print 9 rather than 7.
The way rustc solves this is rather ad-hoc. In rustc, token trees are
allowed to include whole AST fragments, so 1+2 is passed through macro
expansion as a single unit. This is a significant violation of token
tree model.
In rust-analyzer, we intended to handle this in a more elegant way,
using token trees with "invisible" delimiters. The idea was is that we
introduce a new kind of parenthesis, "left $"/"right $", and let the
parser intelligently handle this.
The idea was inspired by the relevant comment in the proc_macro crate:
https://doc.rust-lang.org/stable/proc_macro/enum.Delimiter.html#variant.None
> An implicit delimiter, that may, for example, appear around tokens
> coming from a “macro variable” $var. It is important to preserve
> operator priorities in cases like $var * 3 where $var is 1 + 2.
> Implicit delimiters might not survive roundtrip of a token stream
> through a string.
Now that we are older and wiser, we conclude that the idea doesn't work.
_First_, the comment in the proc-macro crate is wishful thinking. Rustc
currently completely ignores none delimiters. It solves the (1 + 2) * 3
problem by having magical token trees which can't be duplicated:
* https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Frust-analyzer/topic/TIL.20that.20token.20streams.20are.20magic
* https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Handling.20of.20Delimiter.3A.3ANone.20by.20the.20parser
_Second_, it's not like our implementation in rust-analyzer works. We
special-case expressions (as opposed to treating all kinds of $var
captures the same) and we don't know how parser error recovery should
work with these dollar-parenthesis.
So, in this PR we simplify the whole thing away by not pretending that
we are doing something proper and instead just explicitly special-casing
expressions by wrapping them into real `()`.
In the future, to maintain bug-parity with `rustc` what we are going to
do is probably adding an explicit `CAPTURED_EXPR` *token* which we can
explicitly account for in the parser.
If/when rustc starts handling delimiter=none properly, we'll port that
logic as well, in addition to special handling.
