Hidden items in external crate are made public when inline glob re-exported

[SergioBenitez]

Consider a crate parent with the following items:

mod module;

#[doc(hidden)]
pub use module::Hidden;
pub use module::Visible;

where module.rs contains:

pub enum Hidden {  }
pub enum Visible {  }

Now consider a crate foo that inline, glob-exports parent in a module par:

extern crate parent;

pub mod par {
    #[doc(inline)]
    pub use parent::*;
}

The item Hidden is rendered in the rustdocs for foo::par when it shouldn't be.

To work around this issue, #[doc(hidden)] can be applied to the Hidden item in module.rs:

#[doc(hidden)]
pub enum Hidden {  }
pub enum Visible {  }

This workaround only works when #[doc(hidden)] is applied to the source definition.

I just used this sample with the latest nightly (rustdoc 1.30.0-nightly (20dc0c507 2018-09-19)) and it didn't seem to show the Hidden struct? Can you confirm that this is still an issue?

[SergioBenitez]

This is still an issue. I've updated the description with a complete, working example, as well as a workaround that points to the root of the issue (#[doc(hidden)] being ignored on the re-export in parent).

As a matter of update: this is unfortunately still an issue.

Should be fixed by #109697.
