.. title:: clang-tidy - modernize-use-default
modernize-use-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::
Copy-constructor, copy-assignment operator, move-constructor and
move-assignment operator are not supported yet.
