suggest map_or in case_sensitive_file_extension_comparisons
changelog: [`case_sensitive_file_extension_comparisons `]: updated suggestion in the example to use `map_or`
Currently, case_sensitive_file_extension_comparisons suggests using `map(..).unwrap_or(..)` which trips up the `map_unwrap_or` lint. This updates the suggestion to use `map_or`.
Use `CARGO_TARGET_DIR` in compile-test
changelog: none
I have a global `CARGO_TARGET_DIR` set, but forgot to delete the old target dir. `compile-test` was getting tripped up on an outdated `rustfix_missing_coverage.txt` I had in there, keeping me from running tests 😄.
Fix [`non_ascii_literal`] in tests
changelog: Don't lint [`non_ascii_literal`] when using non-ascii comments in tests
changelog: Don't lint [`non_ascii_literal`] when `allow`ed on tests
closes: #7739closes: #8263
Currently, case_sensitive_file_extension_comparisons suggests using
`map(..).unwrap_or(..)` which trips up `map_unwrap_or`. This updates
the suggestion to use map_or.
Add new lint [`positional_named_format_parameters`]
*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: Add new lint [`positional_named_format_parameters`] to warn when named parameters in format strings are used as positional arguments.
Fix if_let_mutex not checking Mutexes behind refs
Fixes#9193
We can always peel references because we are looking for a method-call, for which autoderef applies.

[lint_naming]: https://rust-lang.github.io/rfcs/0344-conventions-galore.html#lints
The lint doesn't really follow the naming conventions. I don't have any better idea so I'm open to suggestions.
Extend `if_then_some_else_none` to also suggest `bool::then_some`
Closes#9094.
changelog: Extend `if_then_some_else_none` to also suggest `bool::then_some`
Use `check_proc_macro` for `missing_const_for_fn`
This uses `@Jarcho's` #8694 implementation to fix `missing_const_for_fn` linting in proc-macros.
I'm not 100% sure what I'm doing here, any feedback is appreciated.
Previously: https://github.com/Jarcho/rust-clippy/pull/1.
Fixes#8854.
changelog: [`missing_const_for_fn`]: No longer lints in proc-macros
Add partialeq_to_none lint
Initial implementation of #9275, adding lint `partialeq_to_none`. This is my first time working on `clippy`, so please review carefully.
I'm unsure especially about the `Sugg`, as it covers the entire `BinOp`, instead of just covering one of the sides and the operator (see the multi-line example). I was unsure if pinpointing the suggestion wouldn't be brittle...
changelog: [`PARTIALEQ_TO_NONE`]: Initial commit
`explicit_auto_deref` changes
fixes#9123fixes#9109fixes#9143fixes#9101
This avoid suggesting code which hits a rustc bug. Basically `&{x}` won't use auto-deref if the target type is `Sized`.
changelog: Don't suggest using auto deref for block expressions when the target type is `Sized`
changelog: Include the borrow in the suggestion for `explicit_auto_deref`
changelog: Don't lint `explicit_auto_deref` on `dyn Trait` return
changelog: Don't lint `explicit_auto_deref` when other adjustments are required
changelog: Lint `explicit_auto_deref` in implicit return positions for closures
