The compiler team's explanation
Visibility is restricted to a module which isn't an ancestor of the current item.
Erroneous code example:
pub mod sea {}
pub (in crate::sea) struct Shark; // error!
fn main() {}To fix this error, we need to move the Shark struct inside the sea module:
pub mod sea {
pub (in crate::sea) struct Shark; // ok!
}
fn main() {}Of course, you can do it as long as the module you're referring to is an ancestor:
pub mod earth {
pub mod sea {
pub (in crate::earth) struct Shark; // ok!
}
}
fn main() {}From rustc --explain E0742 (1.99.0), part of the Rust project, MIT or Apache-2.0. Official page.
