Fix false positive in `manual_flatten`
This pull request fixes false positive in `manual_flatten` in case using a slice of references .
closes: #6893
changelog: fix false positive in `manual_flatten`
This currently creates a field which is always false on GenericParamDefKind for future use when
consts are permitted to have defaults
Update const_generics:default locations
Previously just ignored them, now actually do something about them.
Fix using type check instead of value
Add parsing
This adds all the necessary changes to lower const-generics defaults from parsing.
Change P<Expr> to AnonConst
This matches the arguments passed to instantiations of const generics, and makes it specific to
just anonymous constants.
Attempt to fix lowering bugs
Ignore str::len() in or_fun_call lint.
changelog: Changed `or_fun_call` to ignore `str::len`, in the same way it ignores `slice::len` and `array::len`
Closes#6943
Refactor lints in methods module
This PR refactors methods lints other than the lints I refactored in https://github.com/rust-lang/rust-clippy/pull/6826 and moves some functions to methods/utils.rs.
Basically, I follow the instruction described in #6680.
**For ease of review, I refactored step by step, keeping each commit small.**

search_is_some: add checking for `is_none()`
fixes: #6815
changelog: search_is_some: add checking for `is_none()`.
To be honest I don't know what is the process of renaming the lints. Appreciate any feedback if that needs to be handled differently. Thanks!

`match_wildcard` improvements
fixes: #6604fixes: #5733fixes: #6862#5733 is only fixed in the normal case, if different paths are used for the variants then the same problem will occur. It's cause by `def_path_str` returning an utterly useless result. I haven't dug into why yet.
For #6604 there should be some discussion before accepting this. It's easy enough to change the message rather than disable the lint for `Option` and `Result`.
changelog: Attempt to find a common path prefix for `match_wildcard_for_single_variants` and `wildcard_enum_match_arm`
changelog: Don't lint op `Option` and `Result` for `match_wildcard_for_single_variants` and `wildcard_enum_match_arm`
changelog: Consider `or` patterns and `Self` prefix for `match_wildcard_for_single_variants` and `wildcard_enum_match_arm`
Deprecate `intrinsics::drop_in_place` and `collections::Bound`, which accidentally weren't deprecated
Fixes#82080.
I've taken the liberty of updating the `since` values to 1.52, since an unobservable deprecation isn't much of a deprecation (even the detailed release notes never bothered to mention these deprecations).
As mentioned in the issue I'm *pretty* sure that using a type alias for `Bound` is semantically equivalent to the re-export; [the reference implies](https://doc.rust-lang.org/reference/items/type-aliases.html) that type aliases only observably differ from types when used on unit structs or tuple structs, whereas `Bound` is an enum.
ast/hir: Rename field-related structures
I always forget what `ast::Field` and `ast::StructField` mean despite working with AST for long time, so this PR changes the naming to less confusing and more consistent.
- `StructField` -> `FieldDef` ("field definition")
- `Field` -> `ExprField` ("expression field", not "field expression")
- `FieldPat` -> `PatField` ("pattern field", not "field pattern")
Various visiting and other methods working with the fields are renamed correspondingly too.
The second commit reduces the size of `ExprKind` by boxing fields of `ExprKind::Struct` in preparation for https://github.com/rust-lang/rust/pull/80080.
Don't lint on `Result` and `Option` types.
Considers `or` patterns.
Considers variants prefixed with `Self`
Suggestions will try to find a common prefix rather than just using the full path
