Seems like these can be safely fixed. With one, I was particularly
surprised -- `Some(pats) => &**pats,` in body.rs?
```
cargo clippy --fix -- -A clippy::all -D clippy::explicit_auto_deref
```
I am not certain if this will improve performance,
but it seems having a .clone() without any need should be removed.
This was done with clippy, and manually reviewed:
```
cargo clippy --fix -- -A clippy::all -D clippy::redundant_clone
```
feat: Add an option to hide adjustment hints outside of `unsafe` blocks and functions
As the title suggests: this PR adds an option (namely `rust-analyzer.inlayHints.expressionAdjustmentHints.hideOutsideUnsafe`) that allows to hide adjustment hints outside of `unsafe` blocks and functions:
Requested by `@BoxyUwU` <3
Don't show runnable code lenses in libraries outside of the workspace
Addresses #13664. For now I'm just disabling runnable code lenses since the ones that display the number of references and implementations do work correctly with external code.
Also made a tiny TypeScript change to use the typed `sendNotification` overload.
Mega-sync from `rust-lang/rust`
This essentially implements `@oli-obk's` suggestion here https://github.com/rust-lang/rust-analyzer/pull/13459#issuecomment-1297285607, with `@eddyb's` help.
This PR is equivalent to 14 syncs (back and forth) between `rust-lang/rust` and `rust-lang/rust-analyzer`.
Working from this list (from bottom to top):
```
(x) a2a1d9954⬆️ rust-analyzer
(x) 79923c382⬆️ rust-analyzer
(x) c60b1f641⬆️ rust-analyzer
(x) 8807fc4cc⬆️ rust-analyzer
(x) a99a48e78⬆️ rust-analyzer
(x) 4f55ebbd4⬆️ rust-analyzer
(x) f5fde4df4⬆️ rust-analyzer
(x) 459bbb422⬆️ rust-analyzer

(x) 8231fee46⬆️ rust-analyzer
(x) 22c8c9c40⬆️ rust-analyzer
(x) 9d2cb42a4⬆️ rust-analyzer
```
(This listed was assembled by doing a `git subtree push`, which made a branch, and looking at the new commits in that branch, picking only those that were `⬆️ rust-analyzer` commits)
We used the following commands to simulate merges in both directions:
```shell
TO_MERGE=22c8c9c40 # taken from the list above, bottom to top
git merge --no-edit --no-ff $TO_MERGE
git merge --no-edit --no-ff $(git -C ../rust log --pretty=format:'%cN | %s | %ad => %P' | rg -m1 -F "$(git show --no-patch --pretty=format:%ad $TO_MERGE)" | tee /dev/stderr | rg '.* => \S+ (\S+)$' --replace '$1')
```
We encountered no merge conflicts that Git wasn't able to solve by doing it this way.
Here's what the commit graph looks like (as shown in the Git Lens VSCode extension):

This PR closes#13459
## Does this unbreak `rust->ra` syncs?
Yes, here's how we tried:
In `rust-analyzer`:
* check out `subtree-fix` (this PR's branch)
* make a new branch off of it: `git checkout -b subtree-fix-merge-test`
* simulate this PR getting merged with `git merge master`
In `rust`:
* pull latest master
* make a new branch: `git checkout -b test-change`
* mess with rust-analyzer (I added a comment to `src/tools/rust-analyzer/Cargo.toml`)
* commit
* run `git subtree push -P src/tools/rust-analyzer ra-local final-sync` (this follows the [Clippy sync guide](https://doc.rust-lang.org/nightly/clippy/development/infrastructure/sync.html))
This created a `final-sync` branch in `rust-analyzer`.
In `rust-analyzer`:
* `git merge --no-ff final-sync` (this follows the [Clippy sync guide](https://doc.rust-lang.org/nightly/clippy/development/infrastructure/sync.html))
Now `git log` in `rust-analyzer` shows this:
```

## Does this unbreak `ra->rust` syncs?
Yes, here's how we tried.
From `rust`:
* `git checkout -b sync-from-ra`
* `git subtree pull -P src/tools/rust-analyzer ra-local subtree-fix-merge-test` (this is adapted from the [Clippy sync guide](https://doc.rust-lang.org/nightly/clippy/development/infrastructure/sync.html#performing-the-sync-from-clippy-to-rust-langrust), you would normally use `ra-upstream master` but we're simulating things here)
A commit editor pops up, there was no merge conflicts.
## How do we prevent this from happening again?
Like `@bjorn3` said in https://github.com/rust-lang/rust-analyzer/pull/13459#issuecomment-1293587848
> Whenever syncing from rust-analyzer -> rust you have to immediately sync the merge commit from rust -> rust-analyzer to prevent merge conflicts in the future.
But if we get it wrong again, at least now we have a not-so-painful way to fix it.
Fix: Handle empty `checkOnSave/target` values
This fixes a regression introduced by #13290, in which failing to set `checkOnSave/target` (or `checkOnSave/targets`) would lead to an invalid config.
[Fixes#13660]
Support multiple targets for checkOnSave (in conjunction with cargo 1.64.0+)
This PR adds support for the ability to pass multiple `--target` flags when using
`cargo` 1.64.0+.
## Questions
I needed to change the type of two configurations options, but I did not plurialize the names to
avoid too much churn, should I ?

$ cd !$
$ mkdir .cargo
$ echo '

target = [
"aarch64-apple-darwin",

$ echo '

{
let a = std::fs::read_to_string("/tmp/test-read");
