Trait Renderer

pub trait Renderer: Renderer {
    type Handle: Clone;

    // Required methods
    fn measure_image(&self, handle: &Self::Handle) -> Size<u32>;
    fn draw_image(
        &mut self,
        handle: Self::Handle,
        filter_method: FilterMethod,
        bounds: Rectangle,
        rotation: Radians,
        opacity: f32,
        border_radius: [f32; 4],
    );
}

A Renderer that can render raster graphics.

Required Associated Types

type Handle: Clone

The image Handle to be displayed. Iced exposes its own default implementation of a Handle

Required Methods

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

Returns the dimensions of an image for the given Handle.

fn draw_image( &mut self, handle: Self::Handle, filter_method: FilterMethod, bounds: Rectangle, rotation: Radians, opacity: f32, border_radius: [f32; 4], )

Draws an image with the given Handle and inside the provided bounds.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl Renderer for ()

type Handle = Handle

fn measure_image(&self, _handle: &<() as Renderer>::Handle) -> Size<u32>

fn draw_image( &mut self, _handle: <() as Renderer>::Handle, _filter_method: FilterMethod, _bounds: Rectangle, _rotation: Radians, _opacity: f32, _border_radius: [f32; 4], )

impl Renderer for Renderer

type Handle = Handle

fn measure_image(&self, handle: &<Renderer as Renderer>::Handle) -> Size<u32>

fn draw_image( &mut self, handle: <Renderer as Renderer>::Handle, filter_method: FilterMethod, bounds: Rectangle, rotation: Radians, opacity: f32, border_radius: [f32; 4], )
