Check the return type of `len`. Only integral types, or an `Option` or `Result` wrapping one.
Ensure the return type of `is_empty` matches. e.g. `Option<usize>` -> `Option<bool>`
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!
Fix bad suggestion for `match_single_binding` lint
Fix a bad suggestion that needs curly braces when the target `match` is the body of an arm.
Fixes#6572

`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`
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
Write literal suggestion
fixes: #6768
changelog: Add suggestion to `write_literal` and `print_literal` lints
changelog: Change `use_debug` to point only at the format string
wrong_self_convention: fix lint in case of `to_*_mut` method
fixes#6758
changelog: wrong_self_convention: fix lint in case of `to_*_mut` method. When a method starts with `to_` and ends with `_mut`, clippy expects a `&mut self` parameter, otherwise `&self`.
Any feedback is welcome. I was also thinking if shouldn't we treat `to_` the same way as `as_`. Namely to accept `self` taken: `&self` or `&mut self`.
replace span_lint with span_lint_and_sugg along with error message
fixes: #6874
changelog: none
apologies if this may not be the most idiomatic way of doing it, any advice on changes (if any) would be greatly appreciated.
mem_replace_with_default: recognize some std library ctors
fixes#6562
changelog: mem_replace_with_default: recognize some common constructors equivalent to `Default::default()`
Fix suggestion for `explicit_deref_methods`. Sometimes `&**` is needed, sometimes nothing is needed.
Allow `explicit_deref_methods` to trigger in a few new contexts.
`explicit_deref_methods` will now consider ufcs calls
