🌋 vk-mem-alloc-rs

A very lightweight wrapper around the Vulkan Memory Allocator 🦀

[dependencies]
vk-mem-alloc = "0.2.0"

Simple Vulkan Memory Allocator example

// Create the allocator
let allocator = vk_mem_alloc::create_allocator(&instance, physical_device, &device, None).unwrap();

let buffer_create_info = vk::BufferCreateInfo {
    size,
    usage: vk::BufferUsageFlags::STORAGE_BUFFER,
    ..Default::default()
};

let allocation_create_info = vk_mem_alloc::AllocationCreateInfo {
    usage: vk_mem_alloc::MemoryUsage::AUTO_PREFER_DEVICE,
    ..Default::default()
};

// Create the buffer
let (buffer, allocation, allocation_info) = vk_mem_alloc::create_buffer(allocator, &buffer_create_info, &allocation_create_info).unwrap();

....

// Destroy the buffer
vk_mem_alloc::destroy_buffer(allocator, buffer, allocation);

// Destroy the allocator
vk_mem_alloc::destroy_allocator(allocator);
