+This error indicates that the struct, enum or enum variant cannot be
+instantiated from outside of the defining crate as it has been marked
+as `non_exhaustive` and as such more fields/variants may be added in
+future that could cause adverse side effects for this code.
+
+Erroneous code example:
+
+```ignore (it only works cross-crate)
+#[non_exhaustive]
+pub struct NormalStruct {
+    pub first_field: u16,
+    pub second_field: u16,
+}
+
+let ns = NormalStruct { first_field: 640, second_field: 480 }; // error!
+```
+
+It is recommended that you look for a `new` function or equivalent in the
+crate's documentation.
