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.
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¶
- IgnoreMacros¶
If set to true, the check will not give warnings inside macros and will ignore special members with bodies contain macros or preprocessor directives. Default is true.
