Fields

flags: AllocatorPoolCreateFlags

Use combination of VmaPoolCreateFlagBits.

memory_type_index: u32

Vulkan memory type index to allocate this pool from.

block_size: DeviceSize

Size of a single VkDeviceMemory block to be allocated as part of this pool, in bytes. Optional.

Specify nonzero to set explicit, constant size of memory blocks used by this pool.

Leave 0 to use default and let the library manage block sizes automatically. Sizes of particular blocks may vary. In this case, the pool will also support dedicated allocations.

min_block_count: usize

Minimum number of blocks to be always allocated in this pool, even if they stay empty.

Set to 0 to have no preallocated blocks and allow the pool be completely empty.

max_block_count: usize

Maximum number of blocks that can be allocated in this pool. Optional.

Set to 0 to use default, which is SIZE_MAX, which means no limit.

Set to same value as VmaPoolCreateInfo::minBlockCount to have fixed amount of memory allocated throughout whole lifetime of this pool.

priority: f32

A floating-point value between 0 and 1, indicating the priority of the allocations in this pool relative to other memory allocations.

It is used only when #VMA_ALLOCATOR_CREATE_EXT_MEMORY_PRIORITY_BIT flag was used during creation of the #VmaAllocator object. Otherwise, this variable is ignored.

min_allocation_alignment: DeviceSize

Additional minimum alignment to be used for all allocations created from this pool. Can be 0.

Leave 0 (default) not to impose any additional alignment. If not 0, it must be a power of two. It can be useful in cases where alignment returned by Vulkan by functions like vkGetBufferMemoryRequirements is not enough, e.g. when doing interop with OpenGL.
