Subcrate's privates leak, and then cause linker errors #1690
Description
I'm getting a parent crate to "accidentally" use private functions from a sub-crate private module. The compile succeeds, but then the link fails!
main.rs:
extern crate bar;
fn main() {
let bar = bar::Bar::new();
bar.foo.foo();
}
bar/mod.rs
mod priv_bar;
pub struct Bar {
pub foo: priv_bar::Foo,
}
impl Bar {
pub fn new() -> Bar {
Bar { foo: priv_bar::Foo }
}
}
bar/priv_bar.rs:
pub struct Foo;
impl Foo {
pub fn foo(&self) {
println!("hello world");
}
}
If bar/priv_bar.rs is inlined into bar/mod.rs, this doesn't happen; the correct error message is printed.
