std::pmr::monotonic_buffer_resource::do_is_equal

virtual bool do_is_equal(const std::pmr::memory_resource& other) const noexcept;

(since C++17)

Compare *this with other for identity - memory allocated using a monotonic_buffer_resource can only be deallocated using that same resource.

this == &other.
