Constructs an
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 uses the return value of std:: experimental :: pmr :: get_default_resource ( ) as the upstream memory 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.
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 uses the return value of std:: experimental :: pmr :: get_default_resource ( ) as the upstream memory resource.

Copy constructor is deleted.
Parameters
| opts | - | a pool_options struct containing the constructor options |
| upstream | - | the upstream memory resource to use |
Exceptions

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.
