| modernize-use-equals-default |
| ============================ |
| |
| This check replaces default bodies of special member functions with ``= |
| default;``. The explicitly defaulted function declarations enable more |
| opportunities in optimization, because the compiler might treat explicitly |
| defaulted functions as trivial. |
| |
| .. code-block:: c++ |
| |
| struct A { |
| A() {} |
| ~A(); |
| }; |
| A::~A() {} |
| |
| // becomes |
| |
| struct A { |
| A() = default; |
| ~A(); |
| }; |
| A::~A() = default; |
| |
| .. note:: |
| Move-constructor and move-assignment operator are not supported yet. |
| |
| Options |
| ------- |
| |
| .. option:: IgnoreMacros |
| |
| If set to non-zero, the check will not give warnings inside macros. Default |
| is `1`. |
