Allow `single_component_path_imports` for all macros
Closes: https://github.com/rust-lang/rust-clippy/issues/7923
It can be useful to have `use macro_name` regardless of the visibility. This removes the visibility filter.
changelog: [`single_component_path_imports`]: no longer triggers on macros
Make `search_is_some`s suggestion `MachineApplicable`
My biggest PR to date, about 0.3 Lines have been changed!
Closes https://github.com/rust-lang/rust-clippy/issues/8062
The suggestion seems to work well, as we've received no error reports since the implementation in December. This PR therefore promotes the suggestion to `MachineApplicable`. The tests already include `.fixed` files :)
changelog: [`search_is_some`]: Make more suggestions `MachineApplicable`
new lint: `only_used_in_recursion`
changed:
- added `only_used_in_recursion`.
- fixed code that variables are only used in recursion.
- this would not lint when `unused_variable`
This fixes: #8390

changelog: add lint [`only_used_in_recursion`]
This commit makes `AdtDef` use `Interned`. Much the commit is tedious
changes to introduce getter functions. The interesting changes are in
`compiler/rustc_middle/src/ty/adt.rs`.
