What you've described above is all correct and intended behavior. I
can imagine that it's difficult to port old libraries using the old
behavior, but the idea of the new rules is to as naturally as possibly
expose the visibility of an item.
It wasn't so much that I was balking at the prospect of rewriting my
code, as it was that the rewrite was ending up so voluminous and
roundabout. That said, I think I came up with a solution that seems to
resonate a bit better with me:
pub use mod_a = internal::mod_a::external;
mod internal
{
pub mod mod_a
{
pub struct S { priv m: int }
pub mod external
{
pub use super::S;
impl super::S
{
pub fn pub_api(&self) -> int { self.m }
}
}
pub fn crate_api_2() -> S { S{m: 0} }
}
}
It seems to be a pleasant inversion of what was done with the old
approximate rules, except that you have to root the entire module tree
in a private module to establish the visibility wall (which is still
unfortunate as far as documentation goes).
