Constructs a unsynchronized_pool_resource.
1-4) Constructs a
The overloads not taking
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::pmr::get_default_resource() as the upstream memory resource.5) Copy constructor is deleted.
[edit] Parameters
| opts | - | a std::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 the
allocate() function of the upstream resource throws. It is unspecified if or under what conditions such a call takes place.
