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...

10785: ide: show const value in hover r=jhgg a=jhgg
fixes#10783
I think my original attempt was incorrect, because it looks like `HirDisplay` is used in more places than just the hover.
So, I've attempted it again in 312eafe, this time specifically just rendering the value in `hover::render`
pictoral:

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?

Fixes#8999, fixes#2155
`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
{ ... }

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.
