WebLeveraging polymorphic allocators. The feature we're talking about is polymorphic allocators. To be specific, the std::pmr::polymorphic_allocator and the polymorphic std::pmr::memory_resource class that the allocator uses to allocate memory. In essence, it allows you to easily chain memory resources to make the best use of your memory. WebIf it takes any type in its ctor, the polymorphic_allocator needs to hold some extra space and probably more indirection in call. Also note that polymorphic_allocator doesn't own the memory_resource. If you want, you can always write a wrapper class that does the type erasure for you. PM_ME_A_SPECIAL_MOVE • 5 yr. ago.
