code snippet to reproduce:

src/lib.rs:

#[doc(hidden)]
pub enum Foo {
    Variant,
}

pub type Bar = Foo;

src/main.rs:

fn main() {
    let x = mycrate::Bar::Var$0; // cannot complete Variant
}

I think, when you try to expose Bar as a public type, it gets code completion. But Foo as it has the #[doc(hidden)] attribute, RA doesn't give it code completion even for the inner variant exposed via Bar. The type Foo doesn't get code completion at all.

This is a feature of RA which was completed in this pr.

From the test of #19034, it appears that this is for attributes on variants rather than attributes on enum

[wesley-lewis]

I got your point now! While exposing "hidden" enums RA must complete the variant of the non-hidden public enum.
May I work on this?

@ChayimFriedman2 Is this feature expected?

[ChayimFriedman2]

I don't remember my reasoning back then, however today hiding a non-#[doc(hidden)] variant from a #[doc(hidden)] enum looks obviously incorrect to me.
