rust-cpython: rustdoc improvements By default, `cargo doc` builds the documentation for public constructs only, so we make public those that can. Since `cindex` is not safe, we keep it private. Unfortunately, the macro syntax of rust-cpython doesn't allow us to document the classes directly, so we resort to do that at the module level.
