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, an lvalue of type (possibly const)Tor an rvalue of type const T,
the following are true:
- After the definition T u = v;,
uis equal tov; - T{v} is equal to
v.
