Move-constructs a new std::experimental::shared_ptr object from a std::unique_ptr instance with a different
pointer type.
template<class Target,class Deleter> explicit shared_ptr(unique_ptr<Target,Deleter>&& p);
Target*
is implicitly convertible to T*.
Transfers ownership of the pointer from p
to the newly constructed std::experimental::shared_ptr instance; the
newly-constructed std::experimental::shared_ptr holds a copy
of the Deleter
from the p, which
will be used to destroy the owned pointer when the last std::experimental::shared_ptr instance is
destroyed or reassigned.
this->unique().
this->get()
has the value static_cast<T*>(p.get()) had before the constructor was
invoked. get_deleter<Deleter>(*this) returns a pointer to the deleter
owned by p. p.get()==0.
std::bad_alloc if memory could not
be allocated for the internal control block.
