# Error code E0603

A private item was used outside its scope.

Erroneous code example:

    #![allow(unused)]
    fn main() {
    mod foo {
        const PRIVATE: u32 = 0x_a_bad_1dea_u32; // This const is private, so we
                                                // can't use it outside of the
                                                // `foo` module.
    }

    println!("const value: {}", foo::PRIVATE); // error: constant `PRIVATE`
                                                      //        is private
    }

In order to fix this error, you need to make the item public by using the `pub` keyword. Example:

    #![allow(unused)]
    fn main() {
    mod foo {
        pub const PRIVATE: u32 = 0x_a_bad_1dea_u32; // We set it public by using the
                                                    // `pub` keyword.
    }

    println!("const value: {}", foo::PRIVATE); // ok!
    }
