A graphics compositor that can draw to windows.

Required Associated Types

type Settings: Default

The settings of the backend.

type Renderer: Renderer

The iced renderer of the backend.

type Surface

The surface of the backend.

Required Methods

fn new<W>(settings: Self::Settings, compatible_window: W) -> Result<Self, Error>

where W: Window + Clone,

Creates a new Compositor.

fn create_renderer(&self) -> Self::Renderer

Creates a Self::Renderer for the Compositor.

fn create_surface<W>( &mut self, window: W, width: u32, height: u32, ) -> Self::Surface

where W: Window + Clone,

Crates a new Surface for the given window.

fn configure_surface( &mut self, surface: &mut Self::Surface, width: u32, height: u32, )

Configures a new Surface with the given dimensions.

fn fetch_information(&self) -> Information

Returns Information used by this Compositor.

fn present<T>( &mut self, renderer: &mut Self::Renderer, surface: &mut Self::Surface, viewport: &Viewport, background_color: Color, overlay: &[T], ) -> Result<(), SurfaceError>

where T: AsRef<str>,

Presents the Renderer primitives to the next frame of the given Surface.

fn screenshot<T>( &mut self, renderer: &mut Self::Renderer, surface: &mut Self::Surface, viewport: &Viewport, background_color: Color, overlay: &[T], ) -> Vec<u8>

where T: AsRef<str>,

Screenshots the current Renderer primitives to an offscreen texture, and returns the bytes of the texture ordered as RGBA in the sRGB color space.

Object Safety

This trait is not object safe.
