+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:
+
+```compile_fail,E0364
+mod a {
+    fn foo() {}
+
+    mod a {
+        pub use super::foo; // error!
+    }
+}
+```
+
+The solution to this problem is to ensure that the items that you are
+re-exporting are themselves marked with `pub`:
+
+```
+mod a {
+    pub fn foo() {} // ok!
+
+    mod a {
+        pub use super::foo;
+    }
+}
+```
+
+See the [Use Declarations][use-declarations] section of the reference for
+more information on this topic.
