Defined in header <memory_resource>
class memory_resource;		(since C++17)

The class std::pmr::memory_resource is an abstract interface to an unbounded set of classes encapsulating memory resources.

Member functions

(constructor) (implicitly declared)	constructs a new memory_resource (public member function)
(destructor) [virtual]	destructs an memory_resource (virtual public member function)
operator= (implicitly declared)	Implicitly declared copy assignment operator (public member function)
Public member functions
allocate	allocates memory (public member function)
deallocate	deallocates memory (public member function)
is_equal	compare for equality with another memory_resource (public member function)
Protected member functions
do_allocate [virtual]	allocates memory (virtual protected member function)
do_deallocate [virtual]	deallocates memory (virtual protected member function)
do_is_equal [virtual]	compare for equality with another memory_resource (virtual protected member function)

Non-member-functions

operator==operator!=	compare two memory_resources (function)
