- template <class T>
- struct is_nothrow_swappable : public __tof {};
- __inherit If the expression `swap(declval<T&>(), declval<T&>())` (in a context
- where `std::swap` is visible) is valid and non-throwing, inherits from
- __true_type, otherwise from __false_type.
- __compat This trait requires C++11 for full support. Without C++11 it will
- inherit from __true_type for scalar types (including integral, floating point,
- enumeration, pointer and pointer-to-member types), and from __false_type for
- anything else.
- __header ` #include <boost/type_traits/is_nothrow_swappable.hpp>` or ` #include <boost/type_traits.hpp>`
