Implementations

impl Backend

pub fn new(device: &Device, settings: Settings, format: TextureFormat) -> Self

Creates a new Backend.

pub fn present<T: AsRef<str>>(
    &mut self,
    device: &Device,
    staging_belt: &mut StagingBelt,
    encoder: &mut CommandEncoder,
    frame: &TextureView,
    primitives: &[Primitive],
    viewport: &Viewport,
    overlay_text: &[T]
)

Draws the provided primitives in the given TextureView.

The text provided as overlay will be rendered on top of the primitives. This is useful for rendering debug information.
