Enumeration for issuing commands to a CommandBuffer allocated on the GPU. The enumerations are evaluated upon being issued to an active command buffer and correspond to lower level function calls.

Variants

BeginRecording

Begins recording commands to the GPU. A primary command buffer can only issue this command once.

SetViewports

Fields

start_at: u32

viewports: Vec<ViewPort>

SetScissors

Fields

viewports: Vec<ViewPort>

BeginRenderPass

Fields

render_pass: Rc<RenderPass<RenderBackend>>

surface: Rc<Surface<RenderBackend>>

frame_buffer: Rc<Framebuffer<RenderBackend>>

viewport: ViewPort

EndRenderPass

Ends a currently active render pass.
