+A tuple struct or tuple variant was used in a pattern as if it were a struct or
+struct variant.
+
+Erroneous code example:
+
+```compile_fail,E0769
+enum E {
+    A(i32),
+}
+
+let e = E::A(42);
+
+match e {
+    E::A { number } => { // error!
+        println!("{}", number);
+    }
+}
+```
+
+To fix this error, you can use the tuple pattern:
+
+```
+# enum E {
+#     A(i32),
+# }
+# let e = E::A(42);
+match e {
+    E::A(number) => { // ok!
+        println!("{}", number);
+    }
+}
+```
+
+Alternatively, you can also use the struct pattern by using the correct field
+names and binding them to new identifiers:
+
+```
+# enum E {
+#     A(i32),
+# }
+# let e = E::A(42);
+match e {
+    E::A { 0: number } => { // ok!
+        println!("{}", number);
+    }
+}
+```
