Struct AcquiredFrame 

pub struct AcquiredFrame {
    pub image_index: usize,
    pub frame_index: usize,
    pub ready: Semaphore,
    pub complete: Fence,
    pub invalidate_images: bool,
}

Information necessary to render a frame, from Swapchain::acquire

Fields

image_index: usize

Index of the image to write to in Swapchain::images.

frame_index: usize

Index of the frame in flight, for use tracking your own per-frame resources, which may be accessed immediately after Swapchain::acquire returns.

ready: Semaphore

Must be waited on before accessing the image associated with image_index.

complete: Fence

Must be signaled when access to the image associated with image_index and any per-frame resources associated with frame_index is complete.

invalidate_images: bool

Set whenever Swapchain::images has, and Swapchain::extent and Swapchain::format may have, changed since the last Swapchain::acquire call. Use this to invalidate derived resources like vk::ImageViews and vk::Framebuffers, taking care not to destroy them until at least SwapchainOptions::frames_in_flight new frames have been acquired, including this one.
