cppcoreguidelines-pro-type-cstyle-cast

This check flags all use of C-style casts that perform a static_cast downcast, const_cast, or reinterpret_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. Note that a C-style (T)expression cast means to perform the first of the following that is possible: a const_cast, a static_cast, a static_cast followed by a const_cast, a reinterpret_cast, or a reinterpret_cast followed by a const_cast. This rule bans (T)expression only when used to perform an unsafe cast.

This rule is part of the Type safety (Type.4) profile from the C++ Core Guidelines.
