Module gaclen::graphics::device

The device uses GPU to execute rendering and computing commands.

In order to get an image using a Device one needs to:

1. Create it.
2. Create a render-pass.
3. Create a data-buffer.
4. Start a frame.
5. Draw using a pass.
6. Finish the frame.

Note that during the middle of the frame the device switches to DrawingDevice struct, which represents 'middle of frame' state.

Structs

Device	A device responsible for hardware-accelerated computations.
DrawingDevice	A device that is in the middle of drawing a frame.

Enums

DeviceCreationError	Error during device creation.
FrameFinishError	Error finishing the frame.
PresentMode	The way presenting a swapchain is accomplished.
