 "##,
 
+E0603: r##"
+A private item was used outside its scope.
+
+Erroneous code example:
+
+```compile_fail,E0603
+mod SomeModule {
+    const PRIVATE: u32 = 0x_a_bad_1dea_u32; // This const is private, so we
+                                            // can't use it outside of the
+                                            // `SomeModule` module.
+}
+
+println!("const value: {}", SomeModule::PRIVATE); // error: constant `CONSTANT`
+                                                  //        is private
+```
+
+In order to fix this error, you need to make the item public by using the `pub`
+keyword. Example:
+
+```
+mod SomeModule {
+    pub const PRIVATE: u32 = 0x_a_bad_1dea_u32; // We set it public by using the
+                                                // `pub` keyword.
+}
+
+println!("const value: {}", SomeModule::PRIVATE); // ok!
+```
