Private modules cannot be publicly re-exported. This error indicates that you attempted to pub use
a module that was not itself public.
Erroneous code example:
mod foo { pub const X: u32 = 1; } pub use foo as foo2; fn main() {}
The solution to this problem is to ensure that the module that you are re-exporting is itself marked with pub
:
pub mod foo { pub const X: u32 = 1; } pub use foo as foo2; fn main() {}
