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.
