A render backend bound to a graphics context (or to software rendering).

Required Methods

fn create_render_target( &self, surfaces: &[Arc<dyn IPlatformRenderSurface>], ) -> Rc<dyn IRenderTarget>

Creates a render target for one of the given surfaces.

fn create_offscreen_render_target( &self, pixel_size: PixelSize, scaling: Vector, enable_text_antialiasing: bool, ) -> Rc<dyn IDrawingContextLayerImpl>

Creates an offscreen render target.

fn is_lost(&self) -> bool

Whether the context is lost and must be recreated.

fn max_offscreen_render_target_pixel_size(&self) -> Option<PixelSize>

The largest offscreen render target the context can create, if limited.

fn dispose(&self)

Releases the context.

Provided Methods

fn public_features(&self) -> HashMap<TypeId, Rc<dyn Any>>

The features of the context that are exposed to user code, by type.

fn is_ready_to_create_render_target( &self, _surfaces: &[Arc<dyn IPlatformRenderSurface>], ) -> bool

Whether a render target can be created for the surfaces right now.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
