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, image: Image<Self::Handle>, bounds: Rectangle);
}

Available on crate feature advanced only.

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, image: Image<Self::Handle>, bounds: Rectangle)

Draws an Image 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.
