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.
Closes#10295

10538: fix: matching brace should prefer brace on cursor's right r=Veykril a=codgician
I observed a brace matching issue with the following Rust code:
```rust
let x = (1 + (2 + 3)) * 4;
```
In a situation like `<|>(1 + (2 + 3)) * 4`, the cursor will go to `(1 + (2 + 3)<|>) * 4`, and if user tries to match bracket again it will go like `(1 + <|>(2 + 3)) * 4` while logically the expected result should be `<|>(1 + (2 + 3)) * 4`. This behavior exists in both line cursor style and block cursor style.
This PR fixes this by letting `matching_brace` prefer the brace to cursor's right when the cursor lies between multiple consecutive braces. It **does NOT** fix#1942 but could be related. Please review.

10423: Internal: refactor for mdbook plugin r=Veykril a=HKalbasi
This PR is for upstreaming changes that I made for mdbook plugin. Changes are adding inlay hints to `StaticIndex` and changing some functions for working around privacy of crates.
Aside this, is it okay if I bring the plugin in tree? It is a simple binary crate. I feel it will better maintained here and become resistant to api changes.

This renames `descend_into_macros` to `descend_into_macros_single` and `descend_into_macros_many` into `descend_into_macros`.
However, this does not touch a function in `SemanticsImpl` of same name.

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

10403: feat: Add semantic token modifier for crate root r=Veykril a=lhvy
Resolves#9073
I managed to implement crate root highlighting for crates mentioned specifically by name (e.g. `serde` in `use serde::Serialize;`), but not for crates referred to with `crate` or `super`. How could I implement this?

`builtInCrates` could be an alternate name to `defaultLibrary`, which one is better?

10181: Begining of lsif r=HKalbasi a=HKalbasi
This PR adds a `lsif` command to cli, which can be used as `rust-analyzer lsif /path/to/project > dump.lsif`. It now generates a valid, but pretty useless lsif (only supports folding ranges). The propose of this PR is to discussing about the structure of lsif generator, before starting anything serious.

Consider these expples
{ 92 }
async { 92 }
'a: { 92 }
#[a] { 92 }
Previously the tree for them were
BLOCK_EXPR
{ ... }
EFFECT_EXPR
async
BLOCK_EXPR
{ ... }
EFFECT_EXPR
'a:
BLOCK_EXPR
{ ... }
BLOCK_EXPR
#[a]
{ ... }
As you see, it gets progressively worse :) The last two items are
especially odd. The last one even violates the balanced curleys
invariant we have (#10357) The new approach is to say that the stuff in
`{}` is stmt_list, and the block is stmt_list + optional modifiers
BLOCK_EXPR
STMT_LIST
{ ... }
BLOCK_EXPR
async
STMT_LIST
{ ... }
BLOCK_EXPR
'a:
STMT_LIST
{ ... }
BLOCK_EXPR
#[a]
STMT_LIST

10284: internal: definition based hover functions r=Veykril a=HKalbasi
This is part of #10181 but since it is blocked and `hover.rs` is moving quickly so will cause conflicts, I submitted this PR.
This PR extract some parts of `hover` to `find_definition` (maybe this need to be moved to some other file?) and `hover_for_definition`, with those functions I will be able to calculate definition of every token, and calculate hover (and probably other queries) for each definition only once.

9954: feat: Show try operator propogated types on ranged hover r=matklad a=Veykril
Basically this just shows the type of the inner expression of the `?` expression as well as the type of the expression that the `?` returns from:
Unless both of these types are `core::result::Result` in which case we show the error types only.
If both types are `core::option::Option` with different type params we do not show this special hover either as it would be pointless(instead fallback to default type hover)
Very much open to changes to the hover text here(I suppose we also want to show the actual type of the `?` expression, that is its output type?).
