我试着用这个函数把std::vector<VkImage>
Map到std::vector<vk::raii::ImageView>
,Map的方法是从他们的示例中得到的,所以可能示例是错误的,idk。
std::vector<vk::raii::ImageView> Render::createImageViews(
std::vector<VkImage>& images,
vk::raii::Device& device
) {
std::vector<vk::raii::ImageView> views(images.size());
vk::ImageViewCreateInfo createInfo(
{},
{},
vk::ImageViewType::e2D,
vk::Format::eB8G8R8A8Srgb,
{},
{ vk::ImageAspectFlagBits::eColor, 0, 1, 0, 1 }
);
for (size_t i = 0; i < images.size(); i++) {
createInfo.image = images[i];
views[i] = std::move(
vk::raii::ImageView(device, createInfo)
);
}
return views;
}
然后我得到了这个错误,它会变成这样:

这是我唯一的错误,我敢肯定,这是由这个代码造成的。
我已经检查了vk::raii::ImageView
的定义,它的默认构造函数被标记为已删除。
这是vulkan_raii.hpp
的一个“bug”还是我应该使用非RAII版本来创建VkImage
的图像视图?

不移动右值,直接赋值:
如果删除默认构造函数,则无法执行此操作:
创建空矢量
如果需要,可以保留空间
