Struct SubbufferAllocatorCreateInfo 

pub struct SubbufferAllocatorCreateInfo {
    pub arena_size: u64,
    pub buffer_usage: BufferUsage,
    pub memory_type_filter: MemoryTypeFilter,
    pub _ne: NonExhaustive,
}

Parameters to create a new SubbufferAllocator.

Fields

arena_size: u64

Initial size of an arena in bytes.

Ideally this should fit all the data you need to update per frame. So for example, if you need to allocate buffers of size 1K, 2K and 5K each frame, then this should be 8K. If your data is dynamically-sized then try to make an educated guess or simply leave the default.

The default value is 0.

buffer_usage: BufferUsage

The buffer usage that all allocated buffers should have.

The default value is empty, which must be overridden.

memory_type_filter: MemoryTypeFilter

The memory type filter all buffers should be allocated with.

The default value is MemoryTypeFilter::PREFER_DEVICE.

_ne: NonExhaustive
