An integration of Vulkan Memory Allocator with vulkanalia.

Example

use vulkanalia::prelude::v1_0::*;
use vulkanalia_vma::{self as vma, Alloc};

fn example(instance: &Instance, device: &Device, physical_device: vk::PhysicalDevice) {
    // Create an allocator.
    let allocator_options = vma::AllocatorOptions::new(instance, device, physical_device);
    let allocator = unsafe { vma::Allocator::new(&allocator_options) }.unwrap();

    // Allocate a buffer using the allocator.
    let buffer_create_info = vk::BufferCreateInfo::builder()
        .size(65_536)
        .usage(vk::BufferUsageFlags::VERTEX_BUFFER)
        .sharing_mode(vk::SharingMode::CONCURRENT);
    let allocation_options = vma::AllocationOptions::default();
    let (buffer, allocation) = unsafe { allocator.create_buffer(buffer_create_info, &allocation_options) }.unwrap();

    // Deallocate the buffer using the allocator.
    unsafe { allocator.destroy_buffer(buffer, allocation) };
