Let t_ designate the private data member that is the wrapped pointer-like object.
1) Explicitly defaulted move assignment operator that move assigns this->t_ from p.t_.
2) Assigns std::move(pu.t_) to this->t_.
This overload participates in overload resolution only if
This overload participates in overload resolution only if
U is implicitly convertible to T.3) Assigns std::forward<U>(u) to this->t_.
This overload participates in overload resolution only if
This overload participates in overload resolution only if
U is implicitly convertible to T and std::decay_t<U> is not a specialization of propagate_const.4) Copy assignment operator is explicitly deleted.
propagate_const is non-copyable.Parameters
| p | - | another propagate_const object to move from
|
| pu | - | another propagate_const object of a different specialization to move from
|
| u | - | another object to assign to the contained pointer |
Return value
*this.
