Do not suggest importing inaccessible items Fixes #88472. For this example: ```rust mod a { struct Foo; } mod b { type Bar = Foo; } ``` rustc currently emits: ``` error[E0412]: cannot find type `Foo` in this scope --> test.rs:6:16 | 6 | type Bar = Foo; | ^^^ not found in this scope | help: consider importing this struct | 6 | use a::Foo; | ``` this is incorrect, as applying this suggestion leads to ``` error[E0603]: struct `Foo` is private --> test.rs:6:12 | 6 | use a::Foo; | ^^^ private struct | note: the struct `Foo` is defined here --> test.rs:2:5 | 2 | struct Foo; | ^^^^^^^^^^^ ``` With my changes, I get: ``` error[E0412]: cannot find type `Foo` in this scope --> test.rs:6:16 | 6 | type Bar = Foo; | ^^^ not found in this scope | = note: this struct exists but is inaccessible: a::Foo ``` As for the wildcard mentioned in #88472, I would argue that the warning is actually correct, since the import _is_ unused. I think the real issue is the wrong suggestion, which I have fixed here. |
