Fix allow attribute, items from macros in `items_after_statements`
Fixes#10540
changelog: [`items_after_statements`]: Fixes `#[allow(clippy::items_after_statements)]` when applied to an item, and ignores items after statements from different macro contexts
Make this function work with signed integer types by extracting the
underlying type and finding the min and max values.
Change the signature to make it more consistent:
- The range is now given as an `Expr` in order to extract the type
- The container's path is now passed, and only as an `Option` so that
the function can be called in the general case without a container
fix [`cast_possible_truncation`] offering wrong suggestion for casting float to integer

Wrap `transmutes_expressible_as_ptr_casts` suggestions in parentheses

r? `@Jarcho`
Is this the best way to go about this? `unused_parens` will catch the unnecessary ones but emitting them in the first place isn't ideal
suggest `try_into` when casting to wildcard type;
fix [`cast_possible_truncation`] suggesting useless parenthesis;
remove suggesting for float to float conversion in [`cast_possible_truncation`]

New lint: detect unnecessary struct building
Fixes#10476.
Running this lint on the top 500 crates produced one hit (in `rust-lang/rust-bindgen`) and [a PR has been submitted there](https://github.com/rust-lang/rust-bindgen/pull/2440).
changelog: [`unnecessary_struct_initialization`]: new lint
The lint is very slow as it doesn't cache the deeply nested check for
the attribute. If we cache it, we can reduce the time spent on checking
`rustc_borrowck` from 28s to 9s, which is a nice improvement. In the
profile, the time inside `has_sig_drop_attr` goes from 66% to 0.2%,
which is a lot more reasonable.
See the PR for nice graphs.
Do not propose to simplify a not expression coming from a macro
Fixes#10523
changelog: FP [`nonminimal_bool`]: do not propose to change code coming from a macro
Do not propose to remove `async move` if variables are captured by ref
Fixes#10482
changelog: FP [`redundant_async_block`] Do not propose to remove `async move` if variables are captured by ref
a general type system cleanup
removes the helper functions `traits::fully_solve_X` as they add more complexity then they are worth. It's confusing which of these helpers should be used in which context.
changes the way we deal with overflow to always add depth in `evaluate_predicates_recursively`. It may make sense to actually fully transition to not have `recursion_depth` on obligations but that's probably a bit too much for this PR.
also removes some other small - and imo unnecessary - helpers.
r? types
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.
Issue function modifiers in the right order in manual_async_fn lint
Fixes#10450
changelog: [`manual_async_fn`] output function modifiers in correct order
fix `almost_swapped`: Ignore external macros
Fixes#10421 ; Related to #10499 (Fixing points *1* and *3* from #10421)
changelog: [`almost_swapped`]: Add a check to ignore external macros
Fix `almost_swapped` false positive (`let mut a = b; a = a`)
Fixes `2` in #10421
changelog: [`almost_swapped`]: Fix false positive when a variable is changed to itself. (`a = a`)
The documentation retained "vice versa" from the previous incarnation of
the lint but the lint itself no longer lints against manual `Hash`
implementations with a derived `PartialEq`.
I also adjusted the documentation for `PartialOrd`-`Ord` lint as "vice
versa" seemed a little confusing to me there (as to what it was refering
to exactly.)
Remove `identity_future` indirection
This was previously needed because the indirection used to hide some unexplained lifetime errors, which it turned out were related to the `min_choice` algorithm.
Removing the indirection also solves a couple of cycle errors, large moves and makes async blocks support the `#[track_caller]`annotation.
Fixes https://github.com/rust-lang/rust/issues/104826.
