Struct arcs::components::Viewport

pub struct Viewport {
    pub centre: Point,
    pub pixels_per_drawing_unit: Scale<f64, DrawingSpace, CanvasSpace>,
}

Fields

centre: Point

fn clone(&self) -> Viewport

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for Viewport

type Storage = HashMapStorage<Self>
