fix: doc url link type
fix: #12033
I did some debugging and found the cause looks like to be some doc links' `LinkType` are kept as `Shortcut` which don't make sense for url links.
This PR should resolve both problems in the origin issue, but aside this PR, more work are needed for doc_links.

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.

- don't return the receiver type from method resolution; instead just
return the autorefs/autoderefs that happened and repeat them. This
ensures all the effects like trait obligations and whatever we learned
about type variables from derefing them are actually applied. Also, it
allows us to get rid of `decanonicalize_ty`, which was just wrong in
principle.
- Autoderef itself now directly works with an inference table. Sadly
this has the effect of making it harder to use as an iterator, often
requiring manual `while let` loops. (rustc works around this by using
inner mutability in the inference context, so that things like unifying
types don't require a unique reference.)
- We now record the adjustments (autoref/deref) for method receivers
and index expressions, which we didn't before.
- Removed the redundant crate parameter from method resolution, since
the trait_env contains the crate as well.
- in the HIR API, the methods now take a scope to determine the trait env.
`Type` carries a trait env, but I think that's probably a bad decision
because it's easy to create it with the wrong env, e.g. by using
`Adt::ty`. This mostly didn't matter so far because
`iterate_method_candidates` took a crate parameter and ignored
`self.krate`, but the trait env would still have been wrong in those
cases, which I think would give some wrong results in some edge cases.
Fixes#10058.
In code like this:
```rust
impl<T> Option<T> {
fn as_deref(&self) -> T::Target where T: Deref {}
}
```
when trying to resolve the associated type `T::Target`, we were only
looking at the bounds on the impl (where the type parameter is defined),
but the method can add additional bounds that can also be used to refer
to associated types. Hence, when resolving such an associated type, it's
not enough to just know the type parameter T, we also need to know
exactly where we are currently.
This fixes#11364 (beta apparently switched some bounds around).
11145: feat: add config to use reasonable default expression instead of todo! when filling missing fields r=Veykril a=bnjjj
Use `Default::default()` in struct fields when we ask to fill it instead of putting `todo!()` for every fields
before:
```rust
pub enum Other {
One,
Two,
}
pub struct Test {
text: String,
num: usize,
other: Other,
}
fn t_test() {
let test = Test {<|>};
}
```
after:
```rust
pub enum Other {
One,
Two,
}
pub struct Test {
text: String,
num: usize,
other: Other,
}
fn t_test() {
let test = Test {
text: String::new(),
num: 0,
other: todo!(),
};
}
```

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

10795: Remove unwrap in doc path resolution r=Veykril a=udoprog
I keep hitting this constantly in my project, and I haven't dug very deep into the root cause. But seeing as the project otherwise compiles it appears to be something unsupported is being incorrectly parsed in rust-analyzer which for other cases is handled by returning `None`.

There is no need to descend everything if all we are interested in is the first mapping.
This bring `descend_into_macros` timing in highlighting in `rust-analyzer/src/config.rs` from `154ms - descend_into_macros (2190 calls)` to `24ms - descend_into_macros (2190 calls)` since we use the single variant there(will regress once we want to highlight multiple namespaces again though).

Turns out when highlighting we currently populate the Dynmaps of pretty much every item in a file, who would've known that would be so costly...
Shaves off 250 ms for the integrated benchmark on `rust-analyzer/src/config.rs`.
We are still looking at a heft `154ms - descend_into_macros (2190 calls)` but I feel like this is slowly nearing towards just call overhead.

10563: feat: Make "Generate getter" assist use semantic info r=agluszak a=agluszak
This PR makes "Generate getter" assist use semantic info instead of dealing with types encoded as strings.
Getters for types which are:
- `Copy` no longer return references
- `AsRef<str>` (i.e. `String`) return `&str` (instead of `&String`)
- `AsRef<[T]>` (i.e. `Vec<T>`) return `&[T]` (instead of `&Vec<T>`)
- `AsRef<T>` (i.e. `Box<T>`) return `&T` (instead of `&Box<T>`)
- `Option<T>` return `Option<&T>` (instead of `&Option<T>`)
- `Result<T, E>` return `Result<&T, &E>` (instead of `&Result<T, E>`)
String, Vec, Box and Option were previously handled as special cases.

10440: Fix Clippy warnings and replace some `if let`s with `match` r=Veykril a=arzg
I decided to try fixing a bunch of Clippy warnings. I am aware of this project’s opinion of Clippy (I have read both [rust-lang/clippy#5537](https://github.com/rust-lang/rust-clippy/issues/5537) and [rust-analyzer/rowan#57 (comment)](https://github.com/rust-analyzer/rowan/pull/57#discussion_r415676159)), so I totally understand if part of or the entirety of this PR is rejected. In particular, I can see how the semicolons and `if let` vs `match` commits provide comparatively little benefit when compared to the ensuing churn.
I tried to separate each kind of change into its own commit to make it easier to discard certain changes. I also only applied Clippy suggestions where I thought they provided a definite improvement to the code (apart from semicolons, which is IMO more of a formatting/consistency question than a linting question). In the end I accumulated a list of 28 Clippy lints I ignored entirely.
Sidenote: I should really have asked about this on Zulip before going through all 1,555 `if let`s in the codebase to decide which ones definitely look better as `match` :P
