~memory_resource();

Effects: Destroys this memory_resource.

[[nodiscard]] void* allocate(size_t bytes, size_t alignment = max_align);

Effects: Allocates storage by calling do_allocate(bytes, alignment) and implicitly creates objects within the allocated region of storage.

Returns: A pointer to a suitable created object ([intro.object]) in the allocated region of storage.

Throws: What and when the call to do_allocate throws.

void deallocate(void* p, size_t bytes, size_t alignment = max_align);

Effects: Equivalent to do_deallocate(p, bytes, alignment).

bool is_equal(const memory_resource& other) const noexcept;

Effects: Equivalent to: return do_is_equal(other);
