[`unnecessary_to_owned`]: check that the adjusted type matches target

Fixes #10033.

Before this change, the lint would assume that removing the `.to_string()` in `f(&x.to_string())` would be ok if x is of some type that implements `Deref<Target = str>` and `f` takes a `&str`.
This turns out to not actually be ok if the `to_string` call is some method that exists on `x` directly, which happens if it implements `Display`/`ToString` itself.

Ignore more pointer types in `unnecessary_cast`

Spotted this because

e2c655b4c0/tests/ui/suspicious_to_owned.rs (L9-L10)

currently fails on `aarch64-unknown-linux-gnu` as `c_char` is `u8` there

The current implementation checks for `as alias`, `as _`. This adds things like
- `as *const alias`
- `as *const cfg_dependant`
- `as *const _`

[`redundant_closure`]: special case inclusive ranges

Fixes #10684.

`x..=y` ranges need a bit of special handling in this lint because it desugars to a call to the lang item `RangeInclusiveNew`, where the callee span would be the same as the range expression itself, so the suggestion looked a bit weird. It now correctly suggests `RangeInclusive::new`.

[`useless_vec`]: lint `vec!` invocations when a slice or an array would do

First off, sorry for that large diff in tests. *A lot* of tests seem to trigger the lint with this new change, so I decided to `#![allow()]` the lint in the affected tests to make reviewing this easier, and also split the commits up so that the first commit is the actual logic of the lint and the second commit contains all the test changes. The stuff that changed in the tests is mostly just line numbers now. So, as large as the diff looks, it's not actually that bad. 😅
I manually went through all of these to find out about edge cases and decided to put them in `tests/ui/vec.rs`.

For more context, I wrote about the idea of this PR here: https://github.com/rust-lang/rust-clippy/issues/2262#issuecomment-1579155257 (that explains the logic)

Basically, it now also considers the case where a `Vec` is put in a local variable and the user only ever does things with it that one could also do with a slice or an array. This should catch a lot more cases, and (at least from looking at the tests) it does.

`suspicious_else_formatting`: Don't warn if there is a comment between else and curly bracket

This PR fixes https://github.com/rust-lang/rust-clippy/issues/10273

The idea is that if the only thing after `else` and before `{` is a comment, we will not warn because, probably, the line break was "made" by rustfmt.

  fn deref(&self) -> &Self::Target { &() }
}

let _ = Some(()).as_ref().unwrap_or_else(|| &S); // autoderef `&S` -> `&()`

Add redundant type annotations lint

Hello, I'm trying to add the `redundat_type_annotations` lint.

It's still WIP but I'd like to start gathering some feedbacks to be sure that I'm not doing things 100% wrong :)

Right now it still misses lints like:

- [x] `let foo: u32 = 5_u32`,
- [x] `let foo: String = STest2::func()`
- [x] `let foo: String = self.func()` (`MethodCall`)
- [x] refs
- [ ] Generics

I've some problems regarding the second example above, in the `init` part of the `Local` I have:

```rust

And I'm not sure how to get the return type of the function `STest2::func()` since the resolved path `DefId` points to the struct itself and not the function. Do you have any idea on how I could get this information in this case?

Thanks!

[`unnecessary_lazy_eval`]: don't lint on types with deref impl

Fixes #10437.
This PR changes clippy's util module `eager_or_lazy` to also consider deref expressions whose type has a non-builtin deref impl and not suggest replacing it as that might have observable side effects.
A prominent example might be the `lazy_static` macro, which creates a newtype with a `Deref` impl that you need to go through to get access to the inner value. Going from lazy to eager can make a difference there.

I use `lint_reasons` and `clap`, which is a bit overzealous when it comes to preventing warnings in its macros; it uses a ton of allow attributes on everything to, as ironic as it is, silence warnings. These two now ignore anything from procedural macros.

PS, I think `allow_attributes.rs` should be merged with `attrs.rs` in the future.

Ignore fix for `from_over_into` if the target type contains a `Self` reference

Fixes https://github.com/rust-lang/rust-clippy/issues/10838.

This is my first time contributing here, and the fix is kind of ugly.
I've worked a bit with `quote` and was trying to figure out a way to replace the type in a better way than just a raw string-replace but couldn't quite figure out how to.

The only thing really required to fix this, is to replace all `Self` references with the type stated in the `from` variable, this isn't entirely simple to do with raw strings without creating a mess though.

We need to find and replace all `Self`'s in a variable with `from` but there could be an arbitrary amount, in a lot of different positions. As well as some type that contains the name self, like `SelfVarSelf` which shouldn't be replaced.

The strategy is essentially, if `"Self"` is surrounded on both sides by something that isn't alphanumeric, then we're golden, then trying to make that reasonably efficient.

I would not be offended if the solution is too messy to accept!

new lint: `explicit_into_iter_fn_arg`

Closes #10743.
This adds a lint that looks for `.into_iter()` calls in a call expression to a function that already expects an `IntoIterator`. In those cases, explicitly calling `.into_iter()` is unnecessary.
There were a few instances of this in clippy itself so I fixed those as well in this PR.

manual_let_else: support struct patterns

This adds upon the improvements of #10797 and:

* Only prints `()` around `Or` patterns at the top level (fixing a regression of #10797)
* Supports multi-binding patterns: `let (u, v) = if let (Some(u_i), Ok(v_i)) = ex { (u_i, v_i) } else ...`
* Traverses through tuple patterns: `let v = if let (Some(v), None) = ex { v } else ...`
* Supports struct patterns: `let v = if let S { v, w, } = ex { (v, w) } else ...`

I've found that there is no indication when `#[cfg(features = "...")]` is used incorrectly, which can easily make mistakes hard to spot. When I searched for this code on github, I also found many misuse cases([link](https://github.com/search?q=%23%5Bcfg%28features+language%3ARust&type=code)).

* Address a formatting issue pointed out in https://github.com/rust-lang/rust-clippy/pull/10175/files#r1137091002
* Replace variables inside | patterns in the if let: `let v = if let V::A(v) | V::B(v) = v { v } else ...`
* Support nested patterns: `let v = if let Ok(Ok(Ok(v))) = v { v } else ...`
* Support tuple structs with more than one arg: `let v = V::W(v, _) = v { v } else ...`; note that more than one *capture* is still not supported, so it bails for `let (v, w) = if let E::F(vi, wi) = x { (vi, wi)}`
* Correctly handle .. in tuple struct patterns: `let v = V::X(v, ..) = v { v } else ...`

[`default_constructed_unit_structs`]: do not lint on type alias paths

Type aliases cannot be used as a constructor, so this lint should not trigger in those cases.
I also changed `clippy_utils::is_ty_alias` to also consider associated types since [they kinda are type aliases too](48ec50ae39/compiler/rustc_resolve/src/late/diagnostics.rs (L1520)).

[`unused_async`]: do not consider `await` in nested `async` blocks as used

Fixes #10800.
This PR makes sure that `await` expressions inside of inner `async` blocks don't prevent the lint from triggering.
For example
```rs
async fn foo() {
  async {
    std::future::ready(()).await;
  }
}
```
Even though there *is* a `.await` expression in this function, it's contained in an async block, which means that the enclosing function doesn't need to be `async` too.

Fix missing block for unsafe code

If a block is declared as unsafe, it needs an extra layer of curly braces around it.

Fixes #10808

This code adds handling for `UnsafeSource::UserProvided` block, i.e. `unsafe { ... }`. Note that we do not handle the `UnsafeSource::CompilerGenerated` as it seems to not be possible to generate that with the user code (?), or at least doesn't seem to be needed to be handled explicitly.

There is an issue with this code: it does not add an extra indentation for the unsafe blocks. I think this is a relatively minor concern for such an edge case, and should probably be done by a separate PR (fixing compile bug is more important than getting styling perfect especially when `rustfmt` will fix it anyway)

```rust
// original code
unsafe {
  ...
}

// code that is now generated by this PR
{ unsafe {
  ...
} }

// what we would ideally like to get
{
  unsafe {
    ...
  }
}
```

don't remove `dbg!` in arbitrary expressions

Fixes #9914

The `dbg_macro` lint replaces empty `dbg!` invocations with the empty string in its suggestion, which is not always valid code in certain contexts (e.g. `let _ = dbg!();` becomes `let _ = ;`). This PR changes it to `()`, which should always be valid where `dbg!()` is valid (`dbg!()` with no arguments evaluates to `()`).

It also special-cases "standalone" `dbg!();` expression statements, where it will suggest removing the whole statement entirely like it did before.

I am in doubt if just looking for `pat.span.from_expansion()` would be sufficient instead of looking for both `pat.span.desugaring_kind().is_some()` or `pat.span.from_expansion()`. The tests (including the new one) passes if I leave the only `if pat.span.from_expansion()`. Any feedbacks?

Also, this is my first PR here, sorry for anything and thanks for the patience!

use `is_inside_const_context` for `in_constant` util fn

Fixes #10452.

This PR improves the `in_constant` util function to detect more cases of const contexts. Previously this function would not detect cases like expressions in array length position or expression in an inline const block `const { .. }`.

Add size-parameter to unecessary_box_returns

Fixes #10641

This adds a configuration-knob to the `unecessary_box_returns`-lint which allows _not_ linting a `fn() -> Box<T>` if `T` is "large". The default byte size above which we no longer lint is 128 bytes (due to https://github.com/rust-lang/rust-clippy/issues/4652#issue-505670554, also used in #9373). The overall rational is given in #10641.

Instead of repeating the same logic by walking HIR during metadata encoding.

The only difference is that we are no longer encoding `macro_rules` items, but we never currently need them as a part of this list. They can be encoded separately if this need ever arises.

`module_reexports` is also un-querified, because I don't see any reasons to make it a query, only overhead.

Also, added a test case for the `avoid_breaking_exported_api` config option.

In uninit checking, add fallback for polymorphic types

After #10520, we always assumed that polymorphic types do not allow to be left uninitialized. But we can do better, by peeking into polymorphic types and adding a few special cases for going through tuples, arrays (because the length may be polymorphic) and blanket allowing all unions (like MaybeUninit).

fixes #10551

ff23e48c30 Auto merge of #108471 - clubby789:unbox-the-syntax, r=Nilstrieb,est31
Remove `box_syntax`

r? `@Nilstrieb`

This removes the feature `box_syntax`, which allows the use of `box <expr>` to create a Box, and finalises removing use of the feature from the compiler. `box_patterns` (allowing the use of `box <pat>` in a pattern) is unaffected.
It also removes `ast::ExprKind::Box` - the only way to create a 'box' expression now is with the rustc-internal `#[rustc_box]` attribute.
As a temporary measure to help users move away, `box <expr>` now parses the inner expression, and emits a `MachineApplicable` lint to replace it with `Box::new`

Strengthen state tracking in const-prop

Some/many of the changes are replicated between both the const-prop lint and the const-prop optimization.

Behaviour changes:
- const-prop opt does not give a span to propagated values. This was useless as that span's primary purpose is to diagnose evaluation failure in codegen.
- we remove the `OnlyPropagateInto` mode. It was only used for function arguments, which are better modeled by a write before entry.
- the tracking of assignments and discriminants make clearer that we do nothing in `NoPropagation` mode or on indirect places.

e65ad6f5d0 Auto merge of #10453 - Jarcho:test_utils, r=dswij
Add utility macros to help with writing tests.

Adds two utility macros to help with testing:
* `external` expands to it's argument tokens, but makes them appear to come from an external macro. Helps make tests for `in_external_macro` much more readable.
* `inline_macros` is an attribute macro which allows the use of a pseudo `inline!` macro which expands to it's argument tokens, but makes them appear to be from a crate-local macro expansion. This removes the need to write `macro_rules` boilerplate when testing how lints interact with macros.

---

`external`'s usage is simple. `external!(struct Foo { x: u32});` will make the struct appear as though it came from an external macro. Individual tokens can be escaped if needed. `external!($x + 0 / 10)` will make everything except `x` appear as though it came from an external macro. Can also use `$literal` and `$(tokens...)` as well.

---

`inline_macros` is more complicated due to compiler constraints. Given:
```rust
#[inline_macros]
fn foo() {
    inline!(5 + 5 / 10);
}
```
`inline!(5 + 5 / 10)` will be replace with a call to a generated macro which expands to the contained tokens.

Tokens can be escaped by prefixing them with `$`:
```rust
#[inline_macros]
fn foo() {
    let x = 5;
    inline!($x + 5 / $10);
}
```
This will pass `x` as an `ident` argument and `10` as a `literal` argument.

Token sequences can also be passed with `$(...)`:
```rust
#[inline_macros]
fn foo() {
    let mut x = 5;
    inline!(if $(x >= 5) {
        $x = 5;
    });
}
```
This will pass `x >= 5` as `tt` arguments, and `x` as an `ident` argument.

---

Not 100% sure `inline_macros` is actually worth having. It does make the tests a little easier to read once you're used to it and it becomes more useful once there are multiple macro tests. The verbosity of declaring single use macros starts to hurt at that point.

41fa24cef8 Auto merge of #10415 - schubart:collection_is_never_read, r=llogiq
Add `collection_is_never_read`

Fixes #9267

`@flip1995` and `@llogiq,` I talked with you about this one at Rust Nation in London last week. :-)

This is my first contribution to Clippy, so lots of feedback would be greatly appreciated.

- \[ ] Followed [lint naming conventions][lint_naming]
- \[x] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[x] Added lint documentation
- \[x] Run `cargo dev fmt`

`dogfood` found one true positive (see #9509) and no false positives.

`lintcheck` found no (true or false) positives, even when running on an extended set of crates.

    let lock = mutex.lock().unwrap();
    let rslt = *lock;
    let another = rslt;

manual_let_else: do not suggest semantically different replacements

The problem is that this lint does not consider the possibility that the divergent branch can come first and that the patterns may overlap. This led to incorrect suggestions, previously registered as correct in the tests themselves:

```rust
let v = match build_enum() {
    _ => continue,
    Variant::Bar(v) | Variant::Baz(v) => v,
};
```

had a `let Variant::Bar(v) | Variant::Baz(v) = v else { continue; }` suggestion, which is obviously wrong as the original code `continue`s in any case. Issue #10241 gives another example.

The code now checks that the divergent branch comes second. It could be extended later (I've added a TODO) to check for non-overlapping patterns.

Fixes #10241.

Fixes #6842

This adds a new pedantic `let_underscore_untyped` lint which checks for `let _ = <expr>`, and suggests to either provide a type annotation, or to remove the `let` keyword. That way the author is forced to specify the type they intended to ignore, and thus get forced to re-visit the decision should the type of `<expr>` change. Alternatively, they can drop the `let` keyword to truly just ignore the value no matter what.

to augment the error based on local scope data before returning.
