Trait Layoutable

pub trait Layoutable<Color: PixelColor> {
    // Required methods
    fn size(&self) -> ComponentSize;
    fn draw_placed<DrawError>(
        &self,
        target: &mut impl DrawTarget<Color = Color, Error = DrawError>,
        position: Rectangle,
    ) -> Result<(), DrawError>;
}

Defines any Layoutable element (anything that can be layouted)

Required Methods

fn size(&self) -> ComponentSize

Returns size constraints of that element returns ComponentSize preferred placement constraints of this element

fn draw_placed<DrawError>( &self, target: &mut impl DrawTarget<Color = Color, Error = DrawError>, position: Rectangle, ) -> Result<(), DrawError>

Draws this element onto a defined region onto a target

Arguments

• target: Target where this element should be drawn
• position: place to draw this element onto

returns: Result<(), DrawError>

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.
