Struct iced_graphics::renderer::Renderer

pub struct Renderer<B: Backend> { /* private fields */ }

A backend-agnostic renderer that supports all the built-in widgets.

Implementations

impl<B: Backend> Renderer<B>

pub fn new(backend: B, default_font: Font, default_text_size: Pixels) -> Self

Creates a new Renderer from the given Backend.

pub fn backend(&self) -> &B

Returns a reference to the Backend of the Renderer.

pub fn draw_primitive(&mut self, primitive: Primitive<B::Primitive>)

Enqueues the given Primitive in the Renderer for drawing.

pub fn with_primitives<O>( &mut self, f: impl FnOnce(&mut B, &[Primitive<B::Primitive>]) -> O ) -> O

Runs the given closure with the Backend and the recorded primitives of the Renderer.

pub fn start_layer(&mut self) -> Vec<Primitive<B::Primitive>>

Starts recording a new layer.

pub fn end_layer( &mut self, primitives: Vec<Primitive<B::Primitive>>, bounds: Rectangle )

Ends the recording of a layer.

pub fn start_transformation(&mut self) -> Vec<Primitive<B::Primitive>>

Starts recording a translation.

pub fn end_transformation( &mut self, primitives: Vec<Primitive<B::Primitive>>, transformation: Transformation )

Ends the recording of a translation.

Trait Implementations

impl<B: Debug + Backend> Debug for Renderer<B>

where B::Primitive: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<B: Backend> Renderer for Renderer<B>

fn with_layer(&mut self, bounds: Rectangle, f: impl FnOnce(&mut Self))

Draws the primitives recorded in the given closure in a new layer.

fn with_transformation( &mut self, transformation: Transformation, f: impl FnOnce(&mut Self) )

Applies a Transformation to the primitives recorded in the given closure.

fn fill_quad(&mut self, quad: Quad, background: impl Into<Background>)

Fills a Quad with the provided Background.

fn clear(&mut self)

impl<B> Renderer for Renderer<B>

where B: Backend + Svg,

fn dimensions(&self, handle: &Handle) -> Size<u32>

Returns the default dimensions of an SVG for the given Handle.

fn draw(&mut self, handle: Handle, color: Option<Color>, bounds: Rectangle)
