misc-unconventional-assign-operator

Finds declarations of assign operators with the wrong return and/or argument types and definitions with good return type but wrong return statements.

  • The return type must be Class&.

  • The assignment may be from the class type by value, const lvalue reference, non-const rvalue reference, or from a completely different type (e.g. int).

  • Private and deleted operators are ignored.

  • The operator must always return *this.

This check implements AUTOSAR C++14 Rule A13-2-1.
