Struct Compositor 

pub struct Compositor { /* private fields */ }

A window graphics backend for iced powered by wgpu.

Implementations

impl Compositor

pub async fn request<W: Window>( settings: Settings, compatible_window: Option<W>, shell: Shell, ) -> Result<Self, Error>

Requests a new Compositor with the given Settings.

Returns None if no compatible graphics adapter could be found.

Trait Implementations

impl Compositor for Compositor

type Renderer = Renderer

The iced renderer of the backend.

type Surface = Surface<'static>

The surface of the backend.

async fn with_backend( settings: Settings, _display: impl Display, compatible_window: impl Window, shell: Shell, backend: Option<&str>, ) -> Result<Self, Error>

Creates a new Compositor with a backend preference.

fn create_renderer(&self, settings: Settings) -> Self::Renderer

Creates a Self::Renderer for the Compositor.

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

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 information(&self) -> Information

Returns Information used by this Compositor.

fn present( &mut self, renderer: &mut Self::Renderer, surface: &mut Self::Surface, viewport: &Viewport, background_color: Color, on_pre_present: impl FnOnce(), ) -> Result<(), SurfaceError>

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

fn screenshot( &mut self, renderer: &mut Self::Renderer, viewport: &Viewport, background_color: Color, ) -> Vec<u8>

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

fn new( settings: Settings, display: impl Display + Clone, compatible_window: impl Window + Clone, shell: Shell, ) -> impl Future<Output = Result<Self, Error>>

Creates a new Compositor.

fn load_font(&mut self, font: Cow<'static, [u8]>) -> Result<(), Error>

Loads a font from its bytes.

fn list_fonts(&mut self) -> Result<Vec<Family>, Error>

Lists all the available font families.
