donner::gpu::vulkan::BufferAllocation Struct Reference

Where one buffer's bytes live. More...

#include "donner/gpu/vulkan/VulkanBufferAllocator.h"

Public Attributes
VkDeviceMemory	memory = VK_NULL_HANDLE
	Allocation this buffer was bound into.
VkDeviceSize	offsetBytes = 0
	Offset of this buffer within memory.
void *	mapped = nullptr
	Host pointer to this buffer's first byte.
bool	ownsMemory = false
	Whether releasing this allocation frees memory. False for a suballocation that shares its memory with other buffers still in use.

Detailed Description

Where one buffer's bytes live.

The offset and the host pointer are the buffer's own, not the allocation's: a suballocating implementation hands out many of these pointing into one memory, so a caller must never assume a buffer starts at offset zero of its allocation.

Member Data Documentation

mapped

void* donner::gpu::vulkan::BufferAllocation::mapped = nullptr

Host pointer to this buffer's first byte.

memory

VkDeviceMemory donner::gpu::vulkan::BufferAllocation::memory = VK_NULL_HANDLE

Allocation this buffer was bound into.

offsetBytes

VkDeviceSize donner::gpu::vulkan::BufferAllocation::offsetBytes = 0

Offset of this buffer within memory.

ownsMemory

bool donner::gpu::vulkan::BufferAllocation::ownsMemory = false

Whether releasing this allocation frees memory. False for a suballocation that shares its memory with other buffers still in use.
