Improve `clone_on_copy`
This also removes the `clone_on_copy_mut` test as the same thing is covered in the `clone_on_copy` test.
changelog: `copy_on_clone` lint on chained method calls taking self by value
changelog: `copy_on_clone` only lint when using the `Clone` trait
changelog: `copy_on_clone` correct suggestion when the cloned value is a macro call.
Lint on `_.clone().method()` when method takes self by value
Set applicability correctly
Correct suggestion when the cloned value is a macro call. e.g. `m!(x).clone()`
Don't lint when not using the `Clone` trait
Allow missing panics doc if the panics occur only when debug-assertions is specified
fixes#6970
changelog: `missing_panics_doc`: Allow missing panics doc if the panics occur only when `debug-assertions` is specified.
Improve `expl_impl_clone_on_copy`
fixes: #1254
changelog: Check to see if the generic constraints are the same as if using derive for `expl_impl_clone_on_copy`
`len_without_is_empty` improvements
fixes: #6958fixes: #6972
changelog: Check the return type of `len`. Only integral types, or an `Option` or `Result` wrapping one.
changelog: Ensure the return type of `is_empty` matches. e.g. `Option<usize>` -> `Option<bool>`
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>`
Improve `redundant_slicing`
fixes: #6968
changelog: Fix `redundant_slicing` suggestion when a reborrow might be required or when the value is from a macro call
Fix bad suggestion when a reborrow might be required
Fix bad suggestion when the value being sliced is a macro call
Don't lint inside of a macro due to the previous context sensitive changes
Fix `new_ret_no_self` false positive
fixes: #1724
changelog: Fix false positive with `new_ret_no_self` when returning `Self` with different generic arguments
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
