std::pmr::memory_resource
virtual void * do_allocate( std::size_t bytes, std::size_t alignment ) = 0 ;
(since C++17)

Allocates storage with a size of at least bytes bytes, aligned to the specified alignment.

alignment shall be a power of two.

Exceptions

Throws an exception if storage of the requested size and alignment cannot be obtained.
