Constructs asynchronized_pool_resource.

1-4) Constructs asynchronized_pool_resource using the specified upstream memory resource and tuned according to the specified options. The resulting object holds a copy ofupstream but does not own the resource to whichupstream points.
The overloads not takingopts as a parameter uses a default constructed instance ofpool_options as the options. The overloads not takingupstream as a parameter uses the return value ofstd::pmr::get_default_resource as the upstream memory resource.

5) Copy constructor is deleted.

[edit] Parameters

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

[edit] Exceptions

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