4452f9ec48 internal: improve style
Group related stuff together, use only on path for parsing extern blocks
(they actually have modifiers).

Perhaps we should get rid of items_without_modifiers altogether? Better
to handle these kinds on diagnostics in validation layer...

Merge #9814
9814: Generate default impl when converting `#[derive(Debug)]` to manual impl r=yoshuawuyts a=yoshuawuyts

This patch makes it so when you convert `#[derive(Debug)]` to a manual impl, a default body is provided that's equivalent to the original output of `#[derive(Debug)]`. This should make it drastically easier to write custom `Debug` impls, especially when all you want to do is quickly omit a single field which is `!Debug`.

This is implemented for enums, record structs, tuple structs, empty structs - and it sets us up to implement variations on this in the future for other traits (like `PartialEq` and `Hash`).

Thanks!

## Codegen diff
This is the difference in codegen for record structs with this patch:
```diff
struct Foo {
    bar: String,
}

impl fmt::Debug for Foo {
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
-        todo!();
+        f.debug_struct("Foo").field("bar", &self.bar).finish()
    }
}
```

099b63e7c0 feature: massively improve performance for large files
This story begins in #8384, where we added a smart test for our syntax
highting, which run the algorithm on synthetic files of varying length
in order to guesstimate if the complexity is O(N^2) or O(N)-ish.

The test turned out to be pretty effective, and flagged #9031 as a
change that makes syntax highlighting accidentally quadratic. There was
much rejoicing, for the time being.

Then, lnicola asked an ominous question[1]: "Are we sure that the time
is linear right now?"

Of course it turned out that our sophisticated non-linearity detector
*was* broken, and that our syntax highlighting *was* quadratic.

Investigating that, many brave hearts dug deeper and deeper into the
guts of rust-analyzer, only to get lost in a maze of traits delegating
to traits delegating to macros.

Eventually, matklad managed to peel off all layers of abstraction one by
one, until almost nothing was left. In fact, the issue was discovered in
the very foundation of the rust-analyzer -- in the syntax trees.

Worse, it was not a new problem, but rather a well-know, well-understood
and event (almost) well-fixed (!) performance bug.

The problem lies within `SyntaxNodePtr` type -- a light-weight "address"
of a node in a syntax tree [3]. Such pointers are used by rust-analyzer all
other the place to record relationships between IR nodes and the
original syntax.

Internally, the pointer to a syntax node is represented by node's range.
To "dereference" the pointer, you traverse the syntax tree from the
root, looking for the node with the right range. The inner loop of this
search is finding a node's child whose range contains the specified
range. This inner loop was implemented by naive linear search over all
the children. For wide trees, dereferencing a single `SyntaxNodePtr` was
linear. The problem with wide trees though is that they contain a lot of
nodes! And dereferencing pointers to all the nodes is quadratic in the
size of the file!

The solution to this problem is to speed up the children search --
rather than doing a linear lookup, we can use binary search to locate
the child with the desired interval.

Doing this optimization was one of the motivations (or rather, side
effects) of #6857. That's why `rowan` grew the useful
`child_or_token_at_range` method which does exactly this binary search.

But looks like we've never actually switch to this method? Oups.

Lesson learned: do not leave broken windows in the fundamental infra.
Otherwise, you'll have to repeatedly re-investigate the issue, by
digging from the top of the Everest down to the foundation!

Merge #8813
8813: Get some more array lengths! r=lf- a=lf-

This is built on #8799 and thus contains its changes. I'll rebase it onto master when that one gets merged. It adds support for r-a understanding the length of:

* `let a: [u8; 2] = ...`
* `let a = b"aaa"`
* `let a = [0u8; 4]`

I have added support for getting the values of byte strings, which was not previously there. I am least confident in the correctness of this part and it probably needs some more tests, as we currently have only one test that exercised that part (!).

Fixes #2922.

4f3c0adc5a internal: introduce ast::make::ext module with common shortcuts
There's a tension between keeping a well-architectured minimal
orthogonal set of constructs, and providing convenience functions.
Relieve this pressure by introducing an dedicated module for
non-orthogonal shortcuts.

This is inspired by the django.shortcuts module which serves a similar
purpose architecturally.

8591: Remove SyntaxRewriter usage in insert_use in favor of mutable syntax trees r=matklad a=Veykril

Unfortunately changing `insert_use` to not use `SyntaxRewriter` creates a lot of changes since so much relies on that. But on the other hand this should be the biggest usage of `SyntaxRewriter` I believe.

8524: Fix extract function with partial block selection r=matklad a=brandondong

**Reproduction:**
```rust
fn foo() {
    let n = 1;
    let mut v = $0n * n;$0
    v += 1;
}
```
1. Select the snippet ($0) and use the "Extract into function" assist.
2. Extracted function is incorrect and does not compile:
```rust
fn foo() {
    let n = 1;
    let mut v = fun_name(n);
    v += 1;
}

fn fun_name(n: i32) {}
```
3. Omitting the ending semicolon from the selection fixes the extracted function:
```rust
fn fun_name(n: i32) -> i32 {
    n * n
}
```

**Cause:**
- When `extraction_target` uses a block extraction (semicolon case) instead of an expression extraction (no semicolon case), the user selection is directly used as the TextRange.
- However, the existing function extraction logic for blocks requires that the TextRange spans from start to end of complete statements to work correctly.
- For example:
```rust
fn foo() {
    let m = 2;
    let n = 1;
    let mut v = m $0* n;
    let mut w = 3;$0
    v += 1;
    w += 1;
}
```
produces
```rust
fn foo() {
    let m = 2;
    let n = 1;
    let mut v = m let mut w = fun_name(n);
    v += 1;
    w += 1;
}

fn fun_name(n: i32) -> i32 {
    let mut w = 3;
    w
}
```
- The user selected TextRange is directly replaced by the function call which is now in the middle of another statement. The extracted function body only contains statements that were fully covered by the TextRange and so the `* n` code is deleted. The logic for calculating variable usage and outlived variables for the function parameters and return type respectively search within the TextRange and so do not include `m` or `v`.

**Fix:**
- Only extract full statements when using block extraction. If a user selected part of a statement, extract that full statement.

This PR resolves #7821.
Adds an assist to that converts an `Iterator::for_each` into a for loop: 

```rust
fn main() {
    let vec = vec![(1, 2), (2, 3), (3, 4)];
    x.iter().for_each(|(x, y)| {
        println!("x: {}, y: {}", x, y);
    })
}
```
becomes
```rust
fn main() {
    let vec = vec![(1, 2), (2, 3), (3, 4)];
    for (x, y) in x.iter() {
        println!("x: {}, y: {}", x, y);
    });
}
```

7873: Consider unresolved qualifiers during flyimport r=matklad a=SomeoneToIgnore

Closes https://github.com/rust-analyzer/rust-analyzer/issues/7679

Takes unresolved qualifiers into account, providing better completions (or none, if the path is resolved or do not match).

Does not handle cases when both path qualifier and some trait has to be imported: there are many extra issues with those (such as overlapping imports, for instance) that will require large diffs to address.

Also does not do a fuzzy search on qualifier, that requires some adjustments in `import_map` for better queries and changes to the default replace range which also seems relatively big to include here.

# Features

Supported variants
- break and function does not return => uses `bool` and plain if
- break and function does return => uses `Option<T>` and matches on it
- break with value and function does not return => uses `Option<T>` and if let
- break with value and function does return => uses `Result<T, U>` and matches on t
- same for `return` and `continue`(but we can't continue with value)

Assist does handle nested loops and nested items(like functions, modules, impls)

Try `expr?` operator is allowed together with `return Err(_)` and `return None`.
`return expr` is not allowed.

# Not supported
## Mixing `return` with `break` or `continue`
If we have e.g. a `return` and a `break` in the selected code, it is unclear what the produced code should look like.
We can try `Result<T, Option<U>>` or something like that, but it isn't idiomatic, nor it is established. Otherwise, implementation
is relatively simple.

## `break` with label
Not sure how to handle different labels for multiple `break`s.

[edit] implemented try `expr?`

7535: Extract function assist r=cpud36 a=cpud36

This PR adds `extract function/method` assist. closes #5409.

# Supported features
Assist should support extracting from expressions(`1`, `2 + 2`, `loop { }`) and from a series of statements, e.g.:
```rust
foo();
$0bar();
baz();$0
quix();
```
Assist also supports extracting parameters, like:
```rust
fn foo() -> i32 {
  let n = 1;
  $0n + 1$0
}

// -
fn foo() -> i32 {
  let n = 1;
  fun_name(n)
}

fn fun_name(n: i32) -> i32 {
  n + 1
}
```

Extracting methods also generally works.

Assist allows referencing outer variables, both mutably and immutably, and handles handles access to variables local to extracted function:
```rust
fn foo() {
  let mut n = 1;
  let mut m = 2;
  let mut moved_v = Vec::new();
  let mut ref_mut_v = Vec::new();
  $0
  n += 1;
  let k = 1;
  moved_v.push(n);
  let r = &mut m;
  ref_mut_v.push(*r);
  let h = 3;
  $0
  n = ref_mut_v.len() + k;
  n -= h + m;
}

// -
fn foo() {
  let mut n = 1;
  let mut m = 2;
  let mut moved_v = Vec::new();
  let mut ref_mut_v = Vec::new();
 
  let (k, h) =  fun_name(&mut n, moved_v, &mut m, &mut ref_mut_v);

  n = ref_mut_v.len() + k;
  n -= h + m;
}

fn fun_name(n: &mut i32, mut moved_v: Vec<i32>, m: &mut i32, ref_mut_v: &mut Vec<i32>) -> (i32, i32) {
  *n += 1;
  let k = 1;
  moved_v.push(*n);
  let r = m;
  ref_mut_v.push(*r);
  let h = 3;
  (k, h)
}
```

So we handle both input and output paramters

# Working with non-`Copy` types

Consider the following example:
```rust
fn foo() {
  let v = Vec::new();
  $0
  let n = v.len();
  $0
  let is_empty = v.is_empty();
}
```
`v` must be a parameter to extracted function. 
The question is, what type should it have.
It could be `v: Vec<i32>`, or `v: &Vec<i32>`. 
The former is incorrect for `Vec<i32>`, but the later is silly for `i32`.

To resolve this we need to know if the type implements `Copy` trait.

I didn't find any api available from assists to query this. 
`hir_ty::method_resolution::implements` seems relevant, but is isn't publicly re-exported from `hir`.

# Star(`*`) token and pointer dereference

If I understand correctly, in order to create expression like `*p`, one should use `ast::make::expr_prefix(T![*], ...)`, which
in turn calls `token(T![*])`.

`token` does not have star in `tokens::SOURCE_FILE`, so this panics.
I had to add `*` to `SOURCE_FILE` to make it work.

Correct me if this is not intended way to do this.

# Lowering access `value -> mut ref -> shared ref`

Consider the following example:
```rust
fn foo() {
  let v = Vec::new();
  $0 let n = v.len(); $0
}
```
`v` is not used after extracted function body, so both `v: &Vec<i32>` and `v: Vec<i32>` would work.
Currently the later would be chosen.

We can however check the body of extracted function and conclude that `v: &Vec<i32>` is sufficient.
Using `v: &Vec<i32>`(that is a minimal required access level) might be a better default.
I am unsure.

# Cleanup
The assist seems to be reasonably handling most of common cases.
If there are no concerns with code it produces(i.e. with test cases), I will start cleaning up

[edit]
added showcase

6587: SSR: Support statement matching and replacing r=davidlattimore a=MarijnS95


For #3186

Hi!

This is a smaller initial patchset that came up while working on support for statement lists (and my first time working on RA 😁). It has me stuck on trailing semicolons for which I hope to receive some feedback. Matching (and replacing) `let` bindings with a trailing semicolon works fine, but trying to omit these (to make patterns more ergonomic) turns out more complex than expected.

The "optional trailing semicolon solution" implemented in this PR is ugly because `Matcher::attempt_match_token` should only consume a trailing `;` when parsing `let` bindings to prevent other code from breaking. That at the same time has a nasty side-effect of `;` ending up in the matched code: any replacements on that should include the trailing semicolon as well even if it was not in the pattern. A better example is in the tests:

3ae1649c24/crates/ssr/src/tests.rs (L178-L184)

The end result to achieve is (I guess) allowing replacement of let bindings without trailing semicolon like `let x = $a ==>> let x = 1` (but including them on both sides is still fine), and should make replacement in a macro call (where `foo!(let a = 2;)` for a `$x:stmt` is invalid syntax) possible as well. That should allow to enable/fix these tests:

3ae1649c24/crates/ssr/src/tests.rs (L201-L214)

A possible MVP of this PR might be to drop this optional `;' handling entirely and only allow an SSR pattern/template with semicolons on either side.

Merge #6649
6649: Accept more than just the standard rust literal suffixes in *Number::suffix r=matklad a=Veykril
