std::experimental::propagate_const::operator=(3)

NAME
std::experimental::propagate_const::operator= - std::experimental::propagate_const::operator=

Synopsis
   constexpr propagate_const& operator=( (1) (library fundamentals TS v2)
   propagate_const&& p ) = default;
   template< class U >
   constexpr propagate_const& operator=( (2) (library fundamentals TS v2)
   propagate_const<U>&& pu );
   template< class U > (3) (library fundamentals TS v2)
   constexpr propagate_const& operator=( U&& u );
   propagate_const& operator=( const propagate_const& (4) (library fundamentals TS v2)
   ) = delete;
   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 U is implicitly
   convertible to T.
   3) Assigns std::forward<U>(u) to this->t_.
   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.
