| =============================================== |
| |
| This check flags all usages of ``static_cast``, where a base class is casted to |
| a derived class. In those cases, a fix-it is provided to convert the cast to a |
| ``dynamic_cast``. |
| |
| Use of these casts can violate type safety and cause the program to access a |
| variable that is actually of type ``X`` to be accessed as if it were of an |
| unrelated type ``Z``. |
| |
| This rule is part of the "Type safety" profile of the C++ Core Guidelines, see |
| https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#Pro-type-downcast. |
