Can't use "super" to refer to a name that was brought in by "use" from another crate

Question

I am using super inside a module to refer to names in the parent namespace. However, I cannot get this to work when I refer to a name in the parent namespace that was brought in with a use statement. What am I doing wrong?

// crate mylib

pub fn lib_hello() {println!("Hello from mylib!");}


// crate mybin

extern crate mylib;
use mylib::lib_hello;

fn local_hello() {println!("Hello from here!");}

mod mymod {
    fn f() { super::local_hello() } // Ok
    fn g() { super::lib_hello() }   // error: unresolved name `super::lib_hello`
}

fn main() {
    lib_hello(); // Ok
}

edit: remove pub from local_hello

Further clarification on what I am asking: The function local_hello() is declared as private in the crate namespace. The function lib_hello() is brought in with use and also becomes a private name in the crate namespace. At this point the names local_hello and lib_hello have equal stature: they are both in the crate namespace, and both are private. In mymod I use super to refer to the crate namespace and can get access to local_hello but not lib_hello. What gives?

I know about Python and C++ namespaces. Perhaps there is some crucial bit I need to unlearn?

Answer 1

use statements only import to the local scope. If you want to reexport, use pub use

// crate mylib

pub fn lib_hello() {println!("Hello from mylib!");}


// crate mybin

extern crate mylib;
pub use mylib::lib_hello;

pub fn local_hello() {println!("Hello from here!");}

mod mymod {
    fn f() { super::local_hello() } // Ok
    fn g() { super::lib_hello() }   // error: unresolved name `super::lib_hello`
}

fn main() {
    lib_hello(); // Ok
}

pub use will make the item seem like it exists in the module being reexported from.
