[−][src]Trait coffee::ui::core::Renderer
The renderer of a user interface.
The implementor of this trait will also need to implement the Renderer
trait of the widgets you want to use.
Associated Types
type Configuration: Default
The configuration of the renderer.
It has to implement the Default
trait.
This type allows you to provide a way for your users to customize the renderer. For example, you could make the default text color and size of your configurable, support different fonts, etc.
Required methods
fn load(config: Self::Configuration) -> Task<Self> where
Self: Sized,
Self: Sized,
Loads the renderer with the given configuration.
fn explain(&mut self, layout: &Layout, color: Color)
Explains the Layout
of an Element
for debugging purposes.
This will be called when Element::explain
has been used. It should
explain the Layout
graphically.
fn flush(&mut self, frame: &mut Frame)
Flushes the renderer to draw on the given Frame
.
This method will be called by the runtime after calling Widget::draw
for all the widgets of the user interface.
The recommended strategy to implement a Renderer
is to use Batch
and call Batch::draw
here.
