- `pub(self)` makes an item visible to the current module. This is equivalent
to `pub(in self)`.

> **Edition Differences**: Starting with the 2018 edition, paths for
> `pub(in path)` must start with `crate`, `self`, or `super`. The 2015 edition
> may also use paths starting with `::` or modules from the crate root.

Here's an example:

```rust
pub mod outer_mod {
pub mod inner_mod {
// This function is visible within `outer_mod`
pub(in outer_mod) fn outer_mod_visible_fn() {}
pub(in crate::outer_mod) fn outer_mod_visible_fn() {}
// Same as above, this is only valid in the 2015 edition.
pub(in outer_mod) fn outer_mod_visible_fn_2015() {}

// This function is visible to the entire crate
pub(crate) fn crate_visible_fn() {}
