+Another case that causes this error is when a type is imported into a parent
+module. To fix this, you can follow the suggestion and use File directly or
+`use super::File;` which will import the types from the parent namespace. An
+example that causes this error is below:
+
+```compile_fail,E0412
+use std::fs::File;
+
+mod foo {
+    fn some_function(f: File) {}
+}
+```
+
+```
+use std::fs::File;
+
+mod foo {
+    // either
+    use super::File;
+    // or
+    // use std::fs::File;
+    fn foo(f: File) {}
+}
+# fn main() {} // don't insert it for us; that'll break imports
+```

+A private item was used outside its scope.

+Erroneous code example:
+
+```compile_fail,E0603

+    const PRIVATE: u32 = 0x_a_bad_1dea_u32; // This const is private, so we

+```
+
+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!
+```
