11107: Fix generic type substitution in impl trait with assoc type r=pnevyk a=pnevyk
Fixes#11045
The path transform now detects if a type parameter that is being substituted has an associated type. In that case it is necessary (or safe in general case) to fully qualify the substitution with a trait which the associated type belongs to.
This PR also fixes the previous wrong behavior of the substitution that could create an invalid tree `PATH_TYPE -> PATH_TYPE -> ...`.

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!(),
};
}
```

This has to re-introduce the `sink` pattern, because doing this purely
with iterators is awkward :( Maaaybe the event vector was a false start?
But, anyway, I like the current factoring more -- it sort-of obvious
that we do want to keep ws-attachment business in the parser, and that
we also don't want that to depend on the particular tree structure. I
think `shortcuts` module achieves that.
The general theme of this is to make parser a better independent
library.
The specific thing we do here is replacing callback based TreeSink with
a data structure. That is, rather than calling user-provided tree
construction methods, the parser now spits out a very bare-bones tree,
effectively a log of a DFS traversal.
This makes the parser usable without any *specifc* tree sink, and allows
us to, eg, move tests into this crate.
Now, it's also true that this is a distinction without a difference, as
the old and the new interface are equivalent in expressiveness. Still,
this new thing seems somewhat simpler. But yeah, I admit I don't have a
suuper strong motivation here, just a hunch that this is better.
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').
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...

10546: feat: Implement promote_local_to_const assist r=Veykril a=Veykril
Fixes#7692, that is now one can invoke the `extract_variable` assist on something and then follow that up with this assist to turn it into a const.

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
