◆ move_if_unshared()
template<class T >
| T caf::type_erased_tuple::move_if_unshared | ( | size_t | pos | ) |
Convenience function for moving a value out of the tuple if it is unshared.
Returns a copy otherwise.
◆ shared()
|
virtualnoexcept |
Returns whether multiple references to this tuple exist.
The default implementation returns false.
