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.
