source ·

pub struct ContextData {
    image_key: ImageKey,
    image_desc: WebGPUImageDescriptor,
    image_data: ImageData,
    buffer_ids: ArrayVec<(BufferId, PresentationBufferState), PRESENTATION_BUFFER_COUNT>,

Fields§

§image_key: ImageKey§image_desc: WebGPUImageDescriptor§image_data: ImageData§buffer_ids: ArrayVec<(BufferId, PresentationBufferState), PRESENTATION_BUFFER_COUNT>§swap_chain: Option<SwapChain>

If there is no associated swapchain the context is dummy (transparent black)

§next_presentation_id: PresentationId

Next presentation id to be returned

§current_presentation_id: PresentationId

Current id that is presented/configured

This value only grows

Implementations§

source §

impl ContextData

source
