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