Module vulkano::device::private_data

Store user-defined data associated with Vulkan objects.

A private data slot allows you to associate an arbitrary u64 value with any device-owned Vulkan object. Each private data slot can store one value per object, but you can use the value to look up a larger amount of data in a collection such as a HashMap.

The intended usage is to create one private data slot for every subsystem in your program that needs to assign data to objects independently of the others. That way, different parts of a program manage their own private data and don’t interfere with each other’s data.

When creating a device, it is possible to reserve private data slots ahead of time using DeviceCreateInfo::private_data_slot_request_count. This is not necessary, but it can speed up the use of data slots later.
