Required methods

fn new(settings: Self::Settings) -> (Self, Self::Renderer)

Creates a new Backend and an associated iced renderer.

fn create_surface<W: HasRawWindowHandle>(&mut self, window: &W) -> Self::Surface

Crates a new Surface for the given window.

fn create_swap_chain(
    &mut self,
    surface: &Self::Surface,
    width: u32,
    height: u32
) -> Self::SwapChain

Crates a new SwapChain for the given Surface.

fn draw<T: AsRef<str>>(
    &mut self,
    renderer: &mut Self::Renderer,
    swap_chain: &mut Self::SwapChain,
    output: &<Self::Renderer as Renderer>::Output,
    scale_factor: f64,
    overlay: &[T]
) -> MouseCursor

Draws the output primitives to the next frame of the given SwapChain.
