.. title:: clang-tidy - 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" profile of the C++ Core Guidelines, see
