Trait Implementations

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

type PathType = usize

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

fn num_attributes(&self) -> usize

fn begin(&mut self, at: Point, _attributes: Attributes<'_>) -> 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, _attributes: Attributes<'_>) -> EndpointId

Adds a line segment to the current sub-path.

fn quadratic_bezier_to( &mut self, ctrl: Point, to: Point, _attributes: Attributes<'_>, ) -> EndpointId

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

fn cubic_bezier_to( &mut self, ctrl1: Point, ctrl2: Point, to: Point, _attributes: Attributes<'_>, ) -> 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, attributes: Attributes<'_>)

Applies the provided path event.

fn event(&mut self, event: Event<(Point, Attributes<'_>), Point>)
