std::MoveConstructible – std::MoveConstructible

Synopsis

Defined in header <concepts>

template< class T >                                                                (since C++20)

concept MoveConstructible = std::Constructible<T, T> && std::ConvertibleTo<T, T>;

The concept MoveConstructible is satisfied if T is a reference type, or if it is an object type where an object of that type can constructed from an rvalue of that type in both direct- and copy-initialization contexts, with the usual semantics.
More precisely, if T is an object type, then MoveConstructible<T> is satisfied 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.
