+modernize-use-equals-delete
+===========================
+
+This check marks unimplemented private special member functions with ``= delete``.
+To avoid false-positives, this check only applies in a translation unit that has
+all other member functions implemented.

+.. code-block:: c++
+
+  struct A {
+  private:
+    A(const A&);
+    A& operator=(const A&);
+  };
+
+  // becomes
+
+  struct A {
+  private:
+    A(const A&) = delete;
+    A& operator=(const A&) = delete;
+  };
