template<class U> void delete_object( U* p);		(since C++20)

Destroys the object of typeU and deallocates storage allocated for it.

Equivalent to
std::allocator_traits<polymorphic_allocator>::destroy(*this, p);
deallocate_object(p);

[edit]Parameters

pointer to the object to destroy and deallocate

[edit]Exceptions

Throws nothing.

[edit]Notes

This function was introduced for use with the fully-specialized allocatorstd::pmr::polymorphic_allocator<>, but it may be useful in any specialization.
