resolve: Pre-compute non-reexport module children

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.

Make redundant_async_block a more complete late pass

This lets us detect more complex situations: `async { x.await }` is simplified into `x` if:

- `x` is an expression without side-effect
- or `x` is an `async` block itself

In both cases, no part of the `async` expression can be part of a macro expansion.

Fixes #10509.

Mini-fix `double_must_use` for async functions

From Rust 1.67 onwards, the `#[must_use]` attribute also applies to the `Future::Output` (rust-lang/rust#100633). So the lint `double_must_use` was linting all async functions. This PR changes the `double_must_use` lint so it ignores `async` functions.

Add suggestions to `extra_unused_type_parameters`

Change the `extra_unused_type_parameters` lint to provide machine applicable suggestions rather than just help messages. Exception to this are cases when any unused type parameters appear bounded in where clauses - for now I've deemed these cases unfixable and separated them out. Future work might be able to provide suggestions in these cases.

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).

Really dogfood clippy

The dogfood success condition was inverted in `tests/dogfood.rs`:

```rust
  assert!(!failed_packages.is_empty(), …);
```

while instead the `failed_packages` collection must be empty:

```rust
  assert!(failed_packages.is_empty(), …);

And indeed, several clippy lint source files were not clean and had to be fixed in the process.

rustc has proper heuristics for actually checking whether a type allows
being left uninitialized (by asking CTFE). We can now use this for our

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`

Closes #49733

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.

`@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.

[significant_drop_tightening] Ignore inexpensive statements

Not all statements that follow the last use of a lock guard are expensive and can therefore be ignored by the lint.

```rust
pub fn foo() -> i32 {
    let mutex = Mutex::new(1);
    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.

[needless_return]: Remove all semicolons on suggestion

Closes #10182

Multiple semicolons currently breaks autofix for `needless_return` suggestions. Any semicolons left after removing return means that the return type will always be `()`, and thus fail to compile.

This PR allows `needless_return` to remove multiple semicolons.

The change won't cover the case where there is multiple line yet.

i.e.

```rust
fn needless_return() -> bool {
    return true;
;;
}
```

It's a bit easier to read like this, especially ones that are appending new generics onto an existing list, like ": `, T`" which render somewhat poorly inline.

Add cargo-clippy sysroot test
Whne SYSROOT is defined, clippy-driver will insert a --sysroot argument
when calling rustc. However, when a sysroot argument is already defined,
e.g. through RUSTFLAGS=--sysroot=... the `cargo clippy` call would
error. This tests that the sysroot argument is only passed once and that
SYSROOT is ignored in this case.

Joshua Nelson

Don't pass --sysroot twice if SYSROOT is set
This is useful for rust-lang/rust to allow setting a sysroot that's
*only* for build scripts, different from the regular sysroot passed in
RUSTFLAGS (since cargo doesn't apply RUSTFLAGS to build scripts or
proc-macros).

That said, the exact motivation is not particularly important: this
fixes a regression from
5907e9155e (r1060215684).

Note that only RUSTFLAGS is tested in the new integration test; passing
--sysroot through `clippy-driver` never worked as far as I can tell, and
no one is using it, so I didn't fix it here.

[`drop_ref`]: don't lint idiomatic in match arm

fixes #10122

As established in issue #9482, it is idiomatic to use a single `drop()` expression in a match arm to achieve a side-effect of a function while discarding its output. This should also apply to cases where the function returns a reference.

The change to the lint's code was less than 1 line, because all the heavy lifting was done in PR #9491.

There was an error when trying to negate an expression like `x - 1.0`. We used to format it as `-x - 1.0` whereas a proper negation would be `-(x - 1.0)`.

Therefore, we add parentheses around the expression when it is `ExprKind::Binary`.

We also add parentheses around multiply and divide expressions, even though this is not strictly necessary.

Add size_of_ref lint

This addresses #9995, which is likely raising a valid point about `std::mem::size_of_val()`: It's [very easy to use double-references as the argument](https://github.com/apache/arrow-datafusion/pull/4371#discussion_r1032385224), which the function will happily accept and give back the size of _the reference_, not the size of the value _behind_ the reference. In the worst case, if the value matches the programmer's expectation, this seems to work, while in fact, everything will go horribly wrong e.g. on a different platform.

The size of a `&T` is independent of what `T` is, and people might want to use `std::mem::size_of_val()` to actually get the size of _any_ reference (e.g. via `&&()`). I would rather suggest that this is always bad behavior, though ([instead](https://doc.rust-lang.org/reference/type-layout.html#pointers-and-references-layout), [and](https://doc.rust-lang.org/stable/std/primitive.usize.html#associatedconstant.BITS)). I, therefore, put this lint into `correctness`.

Since the problem is usually easily fixed by removing extra `&`, I went light on suggesting code.

Improve `possible_borrower`

This PR makes several improvements to `clippy_uitls::mir::possible_borrower`. These changes benefit both `needless_borrow` and `redundant clone`.

1. **Use the compiler's `MaybeStorageLive` analysis**

I could spot not functional differences between the one in the compiler and the one in Clippy's repository. So, I removed the latter in favor of the the former.

2. **Make `PossibleBorrower` a dataflow analysis instead of a visitor**

The main benefit of this change is that allows `possible_borrower` to take advantage of statements' relative locations, which is easier to do in an analysis than in a visitor.

This is easier to illustrate with an example, so consider this one:
```rust
    fn foo(cx: &LateContext<'_>, lint: &'static Lint) {
        cx.struct_span_lint(lint, rustc_span::Span::default(), "", |diag| diag.note(&String::new()));
        //                                                                          ^
    }
```
We would like to flag the `&` pointed to by the `^` for removal. `foo`'s MIR begins like this:
```rust
fn span_lint::foo::{closure#0}(_1: [closure@$DIR/needless_borrow.rs:396:68: 396:74], _2: &mut rustc_errors::diagnostic_builder::DiagnosticBuilder<'_, ()>) -> &mut rustc_errors::diagnostic_builder::DiagnosticBuilder<'_, ()> {
    debug diag => _2;                    // in scope 0 at $DIR/needless_borrow.rs:396:69: 396:73
    let mut _0: &mut rustc_errors::diagnostic_builder::DiagnosticBuilder<'_, ()>; // return place in scope 0 at $DIR/needless_borrow.rs:396:75: 396:75
    let mut _3: &mut rustc_errors::diagnostic_builder::DiagnosticBuilder<'_, ()>; // in scope 0 at $DIR/needless_borrow.rs:396:75: 396:100

    let mut _5: &std::string::String;    // in scope 0 at $DIR/needless_borrow.rs:396:85: 396:99
    let _6: std::string::String;         // in scope 0 at $DIR/needless_borrow.rs:396:86: 396:99

    bb0: {
        StorageLive(_3);                 // scope 0 at $DIR/needless_borrow.rs:396:75: 396:100
        StorageLive(_4);                 // scope 0 at $DIR/needless_borrow.rs:396:75: 396:100
        _4 = &mut (*_2);                 // scope 0 at $DIR/needless_borrow.rs:396:75: 396:100
        StorageLive(_5);                 // scope 0 at $DIR/needless_borrow.rs:396:85: 396:99
        StorageLive(_6);                 // scope 0 at $DIR/needless_borrow.rs:396:86: 396:99
        _6 = std::string::String::new() -> bb1; // scope 0 at $DIR/needless_borrow.rs:396:86: 396:99
                                         // mir::Constant
                                         // + span: $DIR/needless_borrow.rs:396:86: 396:97
                                         // + literal: Const { ty: fn() -> std::string::String {std::string::String::new}, val: Value(<ZST>) }
    }

    bb1: {
        _5 = &_6;                        // scope 0 at $DIR/needless_borrow.rs:396:85: 396:99
        _3 = rustc_errors::diagnostic_builder::DiagnosticBuilder::<'_, ()>::note::<&std::string::String>(move _4, move _5) -> [return: bb2, unwind: bb4]; // scope 0 at $DIR/needless_borrow.rs:396:75: 396:100
                                         // mir::Constant
                                         // + span: $DIR/needless_borrow.rs:396:80: 396:84
                                         // + literal: Const { ty: for<'a> fn(&'a mut rustc_errors::diagnostic_builder::DiagnosticBuilder<'_, ()>, &std::string::String) -> &'a mut rustc_errors::diagnostic_builder::DiagnosticBuilder<'_, ()> {rustc_errors::diagnostic_builder::DiagnosticBuilder::<'_, ()>::note::<&std::string::String>}, val: Value(<ZST>) }
    }
```
The call to `diag.note` appears in `bb1` on the line beginning with `_3 =`. The `String` is owned by `_6`. So, in the call to `diag.note`, we would like to know whether there are any references to `_6` besides `_5`.

The old, visitor approach did not consider the relative locations of statements. So all borrows were treated the same, *even if they occurred after the location of interest*.

For example, before the `_3 = ...` call, the possible borrowers of `_6` would be just `_5`. But after the call, the possible borrowers would include `_2`, `_3`, and `_4`.

So, in a sense, the call from which we are try to remove the needless borrow is trying to prevent us from removing the needless borrow(!).

With an analysis, things do not get so muddled. We can determine the set of possible borrowers at any specific location, e.g., using a `ResultsCursor`.

3. **Change `only_borrowers` to `at_most_borrowers`**

`possible_borrowers` exposed a function `only_borrowers` that determined whether the borrowers of some local were *exactly* some set `S`. But, from what I can tell, this was overkill. For the lints that currently use `possible_borrower` (`needless_borrow` and `redundant_clone`), all we really want to know is whether there are borrowers *other than* those in `S`. (Put another way, we only care about the subset relation in one direction.) The new function `at_most_borrowers` takes this more tailored approach.

4. **Compute relations "on the fly" rather than using `transitive_relation`**

The visitor would compute and store the transitive closure of the possible borrower relation for an entire MIR body.

But with an analysis, there is effectively a different possible borrower relation at each location in the body. Computing and storing a transitive closure at each location would not be practical.

So the new approach is to compute the transitive closure on the fly, as needed. But the new approach might actually be more efficient, as I now explain.

In all current uses of `at_most_borrowers` (previously `only_borrowers`), the size of the set of borrowers `S` is at most 2. So you need only check at most three borrowers to determine whether the subset relation holds. That is, once you have found a third borrower, you can stop, since you know the relation cannot hold.

Note that `transitive_relation` is still used by `clippy_uitls::mir::possible_origin` (a kind of "subroutine" of `possible_borrower`).

af39a8a4a8 Identify more cases of useless into_iter() calls
If the type of the result of a call to `IntoIterator::into_iter()`
and the type of the receiver are the same, then the receiver
implements `Iterator` and `into_iter()` is the identity function.

The call to `into_iter()` may be removed in all but two cases:

- If the receiver implements `Copy`, `into_iter()` will produce
  a copy of the receiver and cannot be removed. For example,
  `x.into_iter().next()` will not advance `x` while `x.next()` will.
- If the receiver is an immutable local variable and the call to
  `into_iter()` appears in a larger expression, removing the call to
  `into_iter()` might cause mutability issues. For example, if `x`
  is an immutable local variable, `x.into_iter().next()` will
  compile while `x.next()` will not as `next()` receives
  `&mut self`.

97c12e0460 fix logic in IncrementVisitor
There used to be a logical bug where IncrementVisitor would
completely stop checking an expression/block after seeing a continue
statement. This led to issue #10058 where a variable incremented
(or otherwise modified) after any continue statement would still be
considered incremented only once.

The solution is to continue scanning the expression after seeing a
`continue` statement, but increment self.depth so that the Visitor
thinks that the rest of the loop is within a conditional.

add `suppress_restriction_lint_in_const` config

According to #9808 , add a new lint `suppress_lint_in_const` to report even in const context. BTW, i am not good at naming either, if anyone have a better idea, i am happy to change it.

This PR is still in progress, so i keep it draft.

- \[x] 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`

Fix 10021

This PR proposes a fix for #10021.

The problem is similar to the one that `@mikerite` described in #9505. The compiler is generating an empty substitution for a call, even though the type of `Self` seems to be needed for a predicate. In `@mikerite's` case, the call was to [`IntoFuture::into_future`](https://doc.rust-lang.org/std/future/trait.IntoFuture.html#tymethod.into_future). In this case, the call is to [`Try::branch`](https://doc.rust-lang.org/std/ops/trait.Try.html#tymethod.branch).

The proposed fix is to verify that the parameter whose type is changing has an index within the substitution. The strikes me as a reasonable approach, since if the check were to fail, the following code would be a no-op:

4c123a06ba/clippy_lints/src/methods/unnecessary_to_owned.rs (L420-L428)

Like `@mikerite's` original solution, this solution turns ICEs into false negatives.

Move `unnecessary_unsafety_doc` to `pedantic`

This lint was added in #9822. I like the idea, but also agree with #9986 as well. I think it should at least not be warn-by-default. This is one of these cases, where I'd like a group between pedantic and restriction. But I believe that users using `#![warn(clippy::pedantic)]` will know how to enable the lint if they disagree with it.

1ebdcca8b9 Avoid GenFuture shim when compiling async constructs
Previously, async constructs would be lowered to "normal" generators,
with an additional `from_generator` / `GenFuture` shim in between to
convert from `Generator` to `Future`.

The compiler will now special-case these generators internally so that
async constructs will *directly* implement `Future` without the need
to go through the `from_generator` / `GenFuture` shim.

The primary motivation for this change was hiding this implementation
detail in stack traces and debuginfo, but it can in theory also help
the optimizer as there is less abstractions to see through.

fix for https://github.com/rust-lang/rust-clippy/issues/9427#issuecomment-1295742590

However current implementation gives too many false positive, rending the lint almost useless.

I don't know what's the best way to check if a type has a "significant" drop (in the common meaning, not the internal rustc one, for example Option<(u8, u8)> should not be considered significant)

In that issue's example(s), the lint tried to add a `&` to a value, which implicitly changed the type of a field to a reference. The fix is to add the reference to `receiver_ty` (the type of the receiver of the `to_owned`-like method), before passing `receiver_ty` to `can_change_type`. `can_change_type` properly rejects the modified `receiver_ty`.

cc: `@mikerite` just because I think he was the author of `can_change_type`.

Fix `redundant_closure_for_method_calls` suggestion

Fixes #7746. The issue turns out to be more general than raw pointers. The `redundant_closure_for_method_calls` lint produces incorrect suggestions when the method is associated with a type that must be enclosed in angle brackets or must be written with generic arguments substituted. For example:

```rust
fn main() {
    // Clippy's suggestion: [T; N]::as_slice
    // Correct suggestion:  <[u8; 3]>::as_slice
    let array_opt: Option<&[u8; 3]> = Some(&[4, 8, 7]);
    array_opt.map(|a| a.as_slice());

    // Clippy's suggestion: [T]::len
    // Correct suggestion:  <[u8]>::len
    let slice_opt: Option<&[u8]> = Some(b"slice");
    slice_opt.map(|s| s.len());

    // Clippy's suggestion: *const T::is_null
    // Correct suggestion:  <*const usize>::is_null
    let ptr_opt: Option<*const usize> = Some(&487);
    ptr_opt.map(|p| p.is_null());

    // Clippy's suggestion: dyn TestTrait::method_on_dyn
    // Correct suggestion:  <dyn TestTrait>::method_on_dyn
    let test_struct = TestStruct {};
    let dyn_opt: Option<&dyn TestTrait> = Some(&test_struct);
    dyn_opt.map(|d| d.method_on_dyn());
}

// For the trait object example:
trait TestTrait {}
struct TestStruct {}
impl TestTrait for TestStruct {}

impl dyn TestTrait + '_ {
    fn method_on_dyn(&self) -> bool {
        false
    }
}
```

The issue also affects references and tuples, though I had to patch the standard library with non-trait methods for those types to test that. Just in case, I also included handling for `!`, since it appeared to be possible to call methods on it with angle brackets. I just couldn't verify the resulting suggestion, since dead-code analysis eliminates the code first.

This is my first exposure to Rust compiler internals, so please let me know if I'm taking the wrong approach here!

Closes #9769

The current lint matches all methods with a body of just one expression under the form `(&mut?)? <expr>.field` where field doesn't match the name of the method but there is a field of the same type in `<expr>` that matches the name. This allows matching nested structs, for example for newtype wrappers. This may cast the net a bit too wide and cause false positives. I'll run [clippy_lint_tester](https://github.com/mikerite/clippy_lint_tester) on the top crates to see how frequently false positives happen.

There also may be room for improvement by checking that the replacement field would work taking into account implementations of `Deref` and `DerefMut` even if the types don't exactly match but I don't know yet how this could be done.

Keep original literal notation in suggestion

While I did some investigation of https://github.com/rust-lang/rust-clippy/issues/9866 (I couldn't reproduce it though) I found that `unused_rounding` formats as follows:

```rust
3.0_f64.round() // => 3.0f64
```

This PR makes them preserve as the original notation.

```rust
3.0_f64.round() // => 3.0_f64
```

Return multiple resolutions from `def_path_res`

Changes `def_path_res` to return all the resolutions matching the path rather than the first one (with a namespace hint that covered some cases).  This would fix any issues that come up with multiple versions of the same crate being present as they all have the same crate name

It also adds resolution of `impl _ {}` items for local items, and removes struct field resolution as it didn't seem to be used anywhere

I tested it on a local crate and it worked for the multiple crate issue, but I couldn't come up with a test that worked well with `// aux-build`, maybe `// aux-crate` after https://github.com/rust-lang/rust/pull/103266 could work but I'm not sure on that either

82afb16179 Add variant_name function to LangItem
Clippy has an internal lint that checks for the usage of hardcoded def
paths and suggests to replace them with a lang or diagnostic item, if
possible. This was implemented with a hack, by getting all the variants
of the `LangItem` enum and then index into it with the position of the
`LangItem` in the `items` list. This is no longer possible, because the
`items` list can't be accessed anymore.

feat: lint unchecked subtraction of a 'Duration' from an 'Instant'

Hello all, I tried to tackle the open issue #9371 and this is what I came up with.

I have a difficulty currently - some tests are failing:

```
failures:
    [ui] ui/manual_instant_elapsed.rs
```

The `manual_instant_elapsed` is failing because of `Instant::now() - duration` test, this now gets also picked by `unchecked_duration_subtraction` lint.
What is the correct way to proceed in this case? Simply update the `.stderr` file for `manual_instant_elapsed` lint?

This PR adds new lint `manual_is_ascii_check`, which detects comparison with ascii ranges using `matches!` macros.

As I mentioned as following in the Issue;
> Yes, that's true. we'll start small and then grow it.
> So I'll try to handle matches! macro with single range as suggested above.

However during writing first version, I was thinking that the changes to support alphabetic and digits will be small patch, so I made a single PR in hope review cost can be reduced.

*Please write a short comment explaining your change (or "none" for internal only changes)*

changelog: [`needless_collect`]: Move `needless_collect` to nursery (Now allow-by-default)

After chatting with a few folks, it seems like `needless_collect` is giving false positives pretty regularly (https://github.com/rust-lang/rust-clippy/issues?q=is%3Aissue+is%3Aopen+needless_collect). We're big supporters of clippy in Nushell, and it's one of the passes we require for CI, but we've had to disable this particular lint. Perhaps it should be moved to the nursery until it's improved?

(apologies if this isn't the right approach to disabling a lint by default. I tried to follow the idea I saw other PRs doing in the past)

This implements the `-Ztrack-diagnostics` flag, which uses `#[track_caller]` to track where diagnostics are created. It is meant as a debugging tool much like `-Ztreat-err-as-bug`.

For example, the following code...

```rust
struct A;
struct B;

fn main(){
    let _: A = B;
}
```
...now emits the following error message:

Improve `needless_lifetimes`

This PR makes the following improvements to `needless_lifetimes`.

* It fixes the following false negative, where `foo` is flagged but `bar` is not:
  ```rust
    fn foo<'a>(x: &'a u8, y: &'_ u8) {}

    fn bar<'a>(x: &'a u8, y: &'_ u8, z: &'_ u8) {}
  ```
* It flags more cases, generally. Previously, `needless_borrow` required *all* lifetimes to be used only once. With the changes, individual lifetimes are flagged for being used only once, even if not all lifetimes are.
* Finally, it tries to produce more clear error messages.

changelog: fix `needless_lifetimes` false negative involving functions with multiple unnamed lifetimes
changelog: in `needless_lifetimes`, flag individual lifetimes used only once, rather than require all lifetimes to be used only once

329dc4715b Fix redundant_closure_for_method_calls suggestion
Certain types must be enclosed in angle brackets and must have generic
arguments substituted to create a working suggestion. For example, if
`s` has type `&[u8]`, then `|s| s.len()` may be replaced with
`<[u8]>::len`. Previously, Clippy erroneously suggested `[T]::len`.

AFAICT the only time this would be a valid suggestion is the rather esoteric

```rust
let _ = if let Err(e) = x {
    return Err(e);
} else {
    // no side effects
    x.unwrap()
}

which doesn't seem worth checking to me. Please correct me if I'm missing something.

make ignored internally mutable types for `mutable-key` configurable

We had some false positives where people would create their own types that had interior mutability unrelated to hash/eq. This addition lets you configure this as e.g. `arc-like-types=["bytes::Bytes"]`

This fixes #5325 by allowing users to specify the types whose innards like `Arc` should be ignored (the generic types are still checked) for the sake of detecting inner mutability.

fix: support `map_or` for `or_fun_call` lint

fixes https://github.com/rust-lang/rust-clippy/issues/8993

The methods defined in `KNOW_TYPES`, except for `map_or`, accepts only one argument, so the matching `if let [arg] = args` works only for these methods.
This PR adds `rest_arg` argument to `check_general_case` method and handling of cases with two arguments to support `map_or`.

Mark `let_underscore_lock` and `let_underscore_drop` as uplifted

Here I've renamed both the uplifted lints, however rustc's `let_underscore_lock` is slightly less capable than the clippy lint as it doesn't catch `parking_lot` types or `Result<Guard, ..>`, should we still remove it?

Move MSRV tests into the lint specific test files

There are currently two ways MSRV tests are done in the ui test suite, adding a case to the `#![clippy::msrv = "1.0"]` `tests/ui/min_rust_version_attr.rs` or adding the two `msrv_1_xx` functions to the test file of the lint in question

This updates the clippy book to suggest the `msrv_1_xx` style, and replaces the tests in `tests/ui/min_rust_version_attr.rs` with ones of that style

Almost the entire diff is just moving stuff around as a result, I made sure to check the line numbers the lints are emitted at correspond with the right `msrv` case, so feel free to only skim that part

My understanding is that the latter is currently done by reviewers. Automating this process should make things easier for both reviewers and contributors.

I could make the first bullet a separate PR, or remove it entirely, if desired.

Add a suggestion and a note about orphan rules for `from_over_into`

Adds a machine applicable suggestion to convert the `Into` impl into a `From` one to `from_over_into`

Also adds a note explaining that `impl From<Local> for Foreign` is fine if the `Into` type is foreign

Closes #7444
Addresses half of #9638

Fix edition revision ui tests

#9605 had me wondering how the edition revision tests were working for `manual_assert` but not for `@nyurik,` but it turns out `manual_assert`'s tests weren't working either. I checked how `rust-lang/rust` does it and apparently it comes down to whitespace, `//[rev] edition:X` works 😬

Removes the revisions from `match_wild_err_arm` as I couldn't find any edition dependant behaviour there

fe3200c038 Auto merge of #9584 - royrustdev:implicit_saturating_sub, r=llogiq
add tests in `implicit_saturating_sub` lint

This adds more tests to the `implicit_saturating_sub` lint to rule out certain false positives that have appeared in the past.

Now with those false positives out of the equation, we can move the lint to `style`.

8e87d39f99 Auto merge of #9572 - Nilstrieb:as-ptr-cast-mut, r=dswij
Add `as_ptr_cast_mut` lint

This lint detects calls to a `&self`-taking `as_ptr` method, where the result is then immediately cast to a `*mut T`. Code like this is probably invalid, as that pointer will not have write permissions, and `*mut T` is usually used to write through.
