Public Member Functions
virtual Result< BufferAllocation >	allocate (const VulkanApi &api, VkDevice device, VkBuffer buffer, std::string_view label)=0
	Provides memory for buffer and binds it.
virtual void	release (const VulkanApi &api, VkDevice device, BufferAllocation &allocation)=0
	Releases an allocation obtained from allocate.

Detailed Description

Supplies the memory a buffer is bound into.

Every buffer this backend allocates is host-visible, host-coherent, and persistently mapped: queue writes are a memcpy and readback needs no staging. An implementation must preserve that, because the rest of the backend reads and writes buffers straight through BufferAllocation::mapped with no flush or invalidate of its own.

pure virtual

Releases an allocation obtained from allocate.

Parameters

api	Resolved device entry points.
device	Device owning the allocation.
allocation	Allocation to release; left cleared.
