std::MoveConstructible (3) - Linux Manuals
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.
