Trait Implementations

impl Build for Builder

type PathType = Path

The type of object that is created by this builder.

pub fn build(self) -> Path

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

impl PathBuilder for Builder

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

Starts a new sub-path at a given position.

pub fn end(&mut self, close: bool)

Ends the current sub path.

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

Adds a line segment to the current sub-path.

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

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

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

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

pub 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.

pub fn close(&mut self)

Closes the current sub path.

pub fn path_event(&mut self, event: PathEvent)

Applies the provided path event.

pub fn extend<Evts>(&mut self, events: Evts) where
    Evts: IntoIterator<Item = PathEvent>, 

Adds events from an iterator.

pub fn add_polygon(&mut self, polygon: Polygon<'_, Point>)

Adds a sub-path from a polygon.

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

Adds a sub-path containing a single point.

pub fn add_line_segment(
    &mut self,
    line: &LineSegment<f32>
) -> (EndpointId, EndpointId)

Adds a sub-path containing a single line segment.

pub fn add_ellipse(
    &mut self,
    center: Point,
    radii: Vector,
    x_rotation: Angle,
    winding: Winding
)

    &mut self,
    rect: &Rect,
    radii: &BorderRadii,
    winding: Winding
) where
    Self: Sized, 

Adds a sub-path containing a rectangle.

pub fn flattened(self, tolerance: f32) -> Flattened<Self> where
    Self: Sized, 

Returns a builder that approximates all curves with sequences of line segments.

pub fn transformed<Transform>(
    self,
    transform: Transform
) -> Transformed<Self, Transform> where
    Self: Sized,
