std::Copyable (3) - Linux Man Pages

std::Copyable: std::Copyable

NAME

std::Copyable - std::Copyable

Synopsis


Defined in header <concepts>
template <class T>
concept Copyable =
std::CopyConstructible<T> && (since C++20)
std::Movable<T> &&
std::Assignable<T&, const T&>;


The concept Copyable<T> specifies that T is an Movable object type that can also copied (that is, it supports copy construction and copy assignment).

Notes


It is intended that Copyable<T> also requires std::Assignable<T&, const T> (assignment from const rvalue) and std::Assignable<T&, T&> (assignment from non-const lvalue) to be satisfied.
