std::move_constructible(3) C++ Standard Libary std::move_constructible(3) NAME std::move_constructible - std::move_constructible Synopsis Defined in header <concepts> template< class T > concept move_constructible = std::constructible_from<T, T> && (since C++20) std::convertible_to<T, T>; The concept move_constructible is satisfied if T is a reference type, or if it is an object type where an object of that type can be constructed from an rvalue of that type in both direct- and copy-initialization contexts, with the usual semantics. Semantic requirements If T is an object type, then move_constructible<T> is modeled only if given * rv, an rvalue of type T, and * u2, a distinct object of type T equal to rv, the following are true: * After the definition T u = rv;, u is equal to u2; * T(rv) is equal to u2; and * If T is not const-qualified, then rv's resulting state (after the definition/expression is evaluated in either bullets above) is valid but unspecified; otherwise, it is unchanged.
