template <class T> concept bool CopyConstructible = |
(ranges TS) | |
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 tov
; -
T{v}
is equal tov
.
