Constructs a unsynchronized_pool_resource.
unsynchronized_pool_resource using the specified upstream memory resource and tuned according to the specified options. The resulting object holds a copy of upstream but does not own the resource to which upstream points. opts as a parameter uses a default constructed instance of pool_options as the options. The overloads not taking upstream as a parameter use the return value of std::pmr::get_default_resource() as the upstream memory resource.| opts | - | a std::pmr::pool_options struct containing the constructor options |
| upstream | - | the upstream memory resource to use |
allocate() function of the upstream resource throws. It is unspecified if or under what conditions such a call takes place.
