Converts `::<_>` to an explicit type assignment.
```
let args = args.collect::<Vec<String>>();
```
->
```
let args: Vec<String> = args.collect();
```
Closes#10285
The general problem we are dealing with here is this:
```
macro_rules! thrice {
($e:expr) => { $e * 3}
}
fn main() {
let x = thrice!(1 + 2);
}
```
we really want this to print 9 rather than 7.
The way rustc solves this is rather ad-hoc. In rustc, token trees are
allowed to include whole AST fragments, so 1+2 is passed through macro
expansion as a single unit. This is a significant violation of token
tree model.
In rust-analyzer, we intended to handle this in a more elegant way,
using token trees with "invisible" delimiters. The idea was is that we
introduce a new kind of parenthesis, "left $"/"right $", and let the
parser intelligently handle this.
The idea was inspired by the relevant comment in the proc_macro crate:
https://doc.rust-lang.org/stable/proc_macro/enum.Delimiter.html#variant.None
> An implicit delimiter, that may, for example, appear around tokens
> coming from a “macro variable” $var. It is important to preserve
> operator priorities in cases like $var * 3 where $var is 1 + 2.
> Implicit delimiters might not survive roundtrip of a token stream
> through a string.
Now that we are older and wiser, we conclude that the idea doesn't work.
_First_, the comment in the proc-macro crate is wishful thinking. Rustc
currently completely ignores none delimiters. It solves the (1 + 2) * 3
problem by having magical token trees which can't be duplicated:
* https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Frust-analyzer/topic/TIL.20that.20token.20streams.20are.20magic
* https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Handling.20of.20Delimiter.3A.3ANone.20by.20the.20parser
_Second_, it's not like our implementation in rust-analyzer works. We
special-case expressions (as opposed to treating all kinds of $var
captures the same) and we don't know how parser error recovery should
work with these dollar-parenthesis.
So, in this PR we simplify the whole thing away by not pretending that
we are doing something proper and instead just explicitly special-casing
expressions by wrapping them into real `()`.
In the future, to maintain bug-parity with `rustc` what we are going to
do is probably adding an explicit `CAPTURED_EXPR` *token* which we can
explicitly account for in the parser.
If/when rustc starts handling delimiter=none properly, we'll port that
logic as well, in addition to special handling.

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.

10387: Move `IdxRange` into la-arena r=Veykril a=arzg
Currently, `IdxRange` (named `IdRange`) is located in `hir_def::item_tree`, when really it isn’t specific to `hir_def` and could become part of la-arena. The rename from `IdRange` to `IdxRange` is to maintain consistency with the naming convention used throughout la-arena (`Idx` instead of `Id`, `RawIdx` instead of `RawId`). This PR also adds a few new APIs to la-arena on top of `IdxRange` for convenience, namely:
- indexing into an `Arena` by an `IdxRange` and getting a slice of values back
- creating an `IdxRange` from an inclusive range
Currently this PR also exposes a new `Arena::next_idx` method to make constructing inclusive`IdxRange`s using `IdxRange::new` easier; however, it would in my opinion be better to remove this as it allows for easy creation of out-of-bounds `Idx`s, when `IdxRange::new_inclusive` mostly covers the same use-case while being less error-prone.
I decided to bump the la-arena version to 0.3.0 from 0.2.0 because adding a new `Index` impl for `Arena` turned out to be a breaking change: I had to add a type hint in `crates/hir_def/src/body/scope.rs` when one wasn’t necessary before, since rustc couldn’t work out the type of a closure parameter now that there are multiple `Index` impls. I’m not sure whether this is the right decision, though.

10491: Support nested type on replace if let with match r=k-nasa a=k-nasa
## Why
close: https://github.com/rust-analyzer/rust-analyzer/issues/8690
Now, Replacing if-let with match cant't output exhaustive patterns code.
This was because the `else` conversion used specific types (ex. Option, Result) instead of wildcards.
I thought it was more of a problem to generate non-exhaustive patterns than the benefits of using the concrete one.
How about using wildcards in `else`?
Is this change policy acceptable?
## What
- using wildcards on `make_else_arm`
- Change test cases

10539: Add "generate delegate methods" assist r=Veykril a=yoshuawuyts
_Co-authored with `@rylev_.`
This patch adds a new assist: "generate delegate method" which creates a method that calls to a method defined on an inner field. Delegation is common when authoring newtypes, and having IDE support for this is the best way we can make this easier to author in Rust, bar adding language-level support for it. Thanks!
Closes#5944.
## Example
__before__
```rust
struct Age(u8);
impl Age {
fn age(&self) -> u8 {
self.0
}
}
struct Person {
ag$0e: Age,
}
```
__after__
```rust
struct Age(u8);
impl Age {
fn age(&self) -> u8 {
self.0
}
}
struct Person {
age: Age,
}
impl Person {
$0fn age(&self) -> u8 {
self.age.age()
}
}
```

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.

10503: Only include targets of packages that are workspace members r=Veykril a=bcully
CargoWorkspace's package list includes packages that are path
dependencies, even if those packages aren't actually members of the
cargo workspace. As a result, rust-analyzer's runnable finder, which
returns the target from the first workspace that has a matching package,
may select the wrong working directory, causing runnables to fail, e.g.,
```
error: package `root` cannot be tested because it requires dev-dependencies and is not a member of the workspace
```
To fix this, we filter out packages that aren't members of the workspace
when searching for targets.

10529: Generate `PartialOrd` implementations r=Veykril a=yoshuawuyts

This closes#5946 (which should've been closed already, lol). This PR makes it so we generate `PartialOrd` code implementations where possible. This is the last of Rust's built-in traits that was missing codegen.
After this has been merged we should look at moving the tests to a better spot, and maybe cleaning up the implementation somewhat (it's rather copy-pasty at the moment).
Either way, this finishes up the functionality. Thanks heaps!
