[ER] Help for unresolved super::X imports too. #85249
Description
This code:
mod foo { use super::NonZeroU8; pub(crate) fn bar() -> NonZeroU8 { NonZeroU8::new(1).unwrap() } } use foo::bar; fn main() { let y = NonZeroU8::new(2).unwrap(); }Trying to compile it with rustc (1.54.0-nightly 5c02926 2021-05-11), it gives:
error[E0432]: unresolved import `super::NonZeroU8` --> ...\test.rs:2:9 | 2 | use super::NonZeroU8; | ^^^^^^^^^^^^^^^^ no `NonZeroU8` in the root error[E0433]: failed to resolve: use of undeclared type `NonZeroU8` --> ...\test.rs:12:13 | 12 | let y = NonZeroU8::new(2).unwrap(); | ^^^^^^^^^ not found in this scope | help: consider importing one of these items | 9 | use core::num::NonZeroU8; | 9 | use std::num::NonZeroU8; |I'd like to see the 'use std::num::NonZeroU8;' help for the first unresolved import in the module too.
