Code

This reproduction needs two crates. Crate 1:

pub struct Foo { pub a: bool, #[doc(hidden)] pub b: bool, }

Crate 2:

pub type Foo = crate_1::Foo; fn main() {}

Or, to use public crates.io crates, make a type alias to euclid::Point3D.

Reproduction Steps

cargo doc then visit crate_2::Foo's documentation.

Expected Outcome

The “Aliased Type” of crate_2::Foo is identical to crate_1::Foo.

Actual Output

crate_1::Foo has a /* private fields */ marker in the struct display, but crate_2::Foo does not.

Additional Details

Necessary ingredients to reproduction are that:

• The field is hidden, not private
• The alias is in a different crate than the struct
