- template <class T>
- struct is_complete : public __tof {};
-
- __inherit If `T` is a complete type then inherits from __true_type,
- otherwise inherits from __false_type.
- [important This trait is designed for one use only: to trigger a hard error (via a `static_assert`) when a template
- is accidentally instantiated on an incomplete type. Any other use case will cause ODR violations as the "completeness"
- of type `T` may vary at different points in the current translation unit, as well as across translations units.
- ['[*In particular this trait should never ever be used to change code paths depending on the completeness of a type]].]
- __header ` #include <boost/type_traits/is_complete.hpp>` or ` #include <boost/type_traits.hpp>`
- __compat Requires C++11 SFINAE-expressions to function fully. The macro `BOOST_TT_HAS_WORKING_IS_COMPLETE` is defined
- when the trait is fully functional.
