rustdoc: reexports of hidden items are not hidden, and look confusing

[RalfJung]

I tried searching for the (unstable) Receiver trait in the standard library. The only result it links to is this:

I would expect this to be clickable or have some other way for me to look at the actual definition of this trait. But nothing, the story just ends here.

Looking at the trait, I noticed this:

#[doc(hidden)]
pub trait Receiver {
    // Empty.
}

So probably the doc(hidden) is why we don't get a link. But shouldn't rustdoc then also hide the reexport?

MCVE:

mod deref {
    #[doc(hidden)]
    pub trait Recieve {}
}

pub use deref::Recieve;

You can hide the reexport by putting #[doc(hidden)] above the pub use statement
