Trait Implementations

impl<'a> GraphicsPrimitives for dyn GraphicsContext + 'a

The dynamic graphics context object also implements the graphics primitives

fn rect(&mut self, x1: f32, y1: f32, x2: f32, y2: f32)

Draws a rectangle between particular coordinates

fn circle(&mut self, center_x: f32, center_y: f32, radius: f32)

Draws a circle at a particular point

fn bezier_path<TPath: BezierPath>(&mut self, path: &TPath) where
    TPath::Point: Coordinate2D, 

Draws a bezier path

fn bezier_curve<TCurve: BezierCurve>(&mut self, curve: &TCurve) where
    TCurve::Point: Coordinate2D, 

Draws a bezier curve (defined by the BezierCurve trait)

fn draw_list<'a, DrawIter: 'a + IntoIterator<Item = Draw>>(
    &'a mut self,
    drawing: DrawIter
)

Draws a series of instructions
