Trait Implementations

impl<'l> Build for Builder<'l>

type PathType = usize

The type of object that is created by this builder.

fn build(self) -> usize

Builds a path object and resets the builder so that it can be used again.

impl<'l> PathBuilder for Builder<'l>

fn begin(&mut self, at: Point) -> EndpointId

Starts a new sub-path at a given position.

fn end(&mut self, close: bool)

Ends the current sub path.

fn line_to(&mut self, to: Point) -> EndpointId

Adds a line segment to the current sub-path.

fn quadratic_bezier_to(&mut self, ctrl: Point, to: Point) -> EndpointId

Adds a quadratic bézier curve to the current sub-path.

fn cubic_bezier_to(
    &mut self,
    ctrl1: Point,
    ctrl2: Point,
    to: Point
) -> EndpointId

Adds a cubic bézier curve to the current sub-path.

fn reserve(&mut self, endpoints: usize, ctrl_points: usize)

Hints at the builder that a certain number of endpoints and control points will be added.

fn close(&mut self)

Closes the current sub path.

fn path_event(&mut self, event: PathEvent)
