template <class T>
struct is_nothrow_move_constructible : public true_type-or-false_type {};
Inherits: If T is a (possibly cv-qualified)
type with a non-throwing move-constructor or a type without move-constructor
but with non-throwing copy-constructor, then inherits from true_type,
otherwise inherits from false_type.
Type T must be a complete
type.
In other words, inherits from true_type
only if expression T(std::move(variable1)) won't throw (variable1
is a variable of type T).
Compiler Compatibility: Without some (C++11
noexcept shall work correctly) help from the compiler, is_nothrow_move_constructible
will never report that a class or struct has a non-throwing copy-constructor;
this is always safe, if possibly sub-optimal. Currently (February 2013) MSVC-12.0,
Clang and GCC 4.7 have the necessary compiler support to ensure that this
trait "just works".
