Fields

all_resources: SlotMap<Handle, Arc<DynamicResource<Handle, Desc, Res>>>

All resources, including both resources that are in use and those that are marked as dead via Self::last_frame_deallocated

We store any ref counted handle we give out in DynamicResourcePool::alloc here in order to keep it alive. Every DynamicResourcePool::begin_frame we check if the pool is now the only owner of the handle and if so mark it as deallocated.

last_frame_deallocated: HashMap<Desc, SmallVec<[Handle; 4]>>

Any resource that has been deallocated last frame. We keep them around for a bit longer to allow reclamation
