Constructs a unsynchronized_pool_resource.

1-4) Constructs an 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.
The overloads not taking 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.

5) Copy constructor is deleted.

Parameters

opts	-	a std::pmr::pool_options struct containing the constructor options
upstream	-	the upstream memory resource to use

Exceptions

1-4) Throws only if a call to the allocate() function of the upstream resource throws. It is unspecified if or under what conditions such a call takes place.
