use `IntoIterator::into_iter(..)` instead of `.into_iter()` to explicitly iterate by value lint-enum-intrinsics-mem-discriminant = the return value of `mem::discriminant` is unspecified when called with a non-enum type .note = the argument to `discriminant` should be a reference to an enum, but it was passed a reference to a `{$ty_param}`, which is not an enum. lint-enum-intrinsics-mem-variant = the return value of `mem::variant_count` is unspecified when called with a non-enum type .note = the type parameter of `variant_count` should be an enum, but it was instantiated with the type `{$ty_param}`, which is not an enum. lint-expectation = this lint expectation is unfulfilled .note = the `unfulfilled_lint_expectations` lint can't be expected and will always produce this message

text flow control {$count -> [one] codepoint *[other] codepoints } .note = these kind of unicode codepoints change the way text flows on applications that support them, but can cause confusion because they change the order of characters on the screen .suggestion-remove = if their presence wasn't intentional, you can remove them .suggestion-escape = if you want to keep them but make them visible in your source code, you can escape them .no-suggestion-note-escape = if you want to keep them but make them visible in your source code, you can escape them: {$escaped} lint-default-hash-types = prefer

`CString` is deallocated at the end of the statement, bind it to a variable to extend its lifetime .note = pointers do not have a lifetime; when calling `as_ptr` the `CString` will be deallocated at

this situation does nothing .label = unnecessary method call .note = the type `{$receiver_ty}` which `{$method}` is being called on is the same as the type returned from `{$method}`, so the method call does not do anything and can be removed lint-pass-by-value = passing `{$ty}` by reference .suggestion = try passing by value lint-redundant-semicolons = unnecessary trailing {$multiple -> [true] semicolons *[false] semicolon } .suggestion = remove {$multiple -> [true] these semicolons *[false] this semicolon } lint-drop-trait-constraints = bounds on `{$predicate}` are most likely incorrect,
