std::experimental::ranges::CopyConstructible(3) C++ Standard Libary std::experimental::ranges::CopyConstructible(3)

NAME

std::experimental::ranges::CopyConstructible - std::experimental::ranges::CopyConstructible

Synopsis


Defined in header <experimental/ranges/concepts>
template <class T>


concept bool CopyConstructible =
MoveConstructible<T> && (ranges TS)
Constructible<T, T&> && ConvertibleTo<T&, T> &&
Constructible<T, const T&> && ConvertibleTo<const T&, T> &&


Constructible<T, const T> && ConvertibleTo<const T, T>;


The concept CopyConstructible is satisfied if T is an lvalue reference type, or if
it is a MoveConstructible object type where an object of that type can constructed
from a (possibly const) lvalue or const rvalue of that type in both direct- and
copy-initialization contexts with the usual semantics (a copy is constructed with
the source unchanged).


More precisely, if T is an object type, then CopyConstructible<T> is satisfied only
if given


* v, a lvalue of type (possibly const) T or an rvalue of type const T,


the following are true:


* After the definition T u = v;, u is equal to v;
* T{v} is equal to v.
