Wildcard imports from super omit non-public constants and statics. #37434
Description
Please consider the following code:
const CONSTANT: usize = 0;
mod ok {
use super::CONSTANT;
fn foobar() -> usize {
CONSTANT
}
}
mod error {
use super::*;
fn foobar() -> usize {
CONSTANT
}
}The ok::foobar compiles fine while error::foobar generates the following error:
error[E0425]: unresolved name `CONSTANT`
--> test.rs:13:9
|
13 | CONSTANT
| ^^^^^^^^ unresolved name
This also affects static.
Marking the constant pub makes it compile as expected.

Actually, sorry, it seems that this isn't specific to constants; a wildcard doesn't import anything non-public.
Is this intended? I'd expect a
*to expand to everything that is importable from a given scope, not only what is public.petrochenkov commentedon Oct 27, 2016
The code will compile if you add
#![feature(item_like_imports)]to the crate root.After #37127 lands,
item_like_importswill become a default and the code will work without anyfeatures.koute commentedon Oct 27, 2016
@petrochenkov I see; thanks!
Sorry for the duplicate bug! I did try to search for duplicates, but it seems that my search-fu wasn't strong enough.

@koute: you can still close it. 🙂
