Struct Builder

pub struct Builder { /* private fields */ }

Available on crate feature geometry only.

A Path builder.

Once a Path is built, it can no longer be mutated.

Implementations

impl Builder

pub fn new() -> Builder

Creates a new Builder.

pub fn move_to(&mut self, point: Point)

Moves the starting point of a new sub-path to the given Point.

pub fn line_to(&mut self, point: Point)

Connects the last point in the Path to the given Point with a straight line.

pub fn arc(&mut self, arc: Arc)

Adds an Arc to the Path from start_angle to end_angle in a clockwise direction.

pub fn arc_to(&mut self, a: Point, b: Point, radius: f32)

Adds a circular arc to the Path with the given control points and radius.

This essentially draws a straight line segment from the current position to a, but fits a circular arc of radius tangent to that segment and tangent to the line between a and b.

With another .line_to(b), the result will be a path connecting the starting point and b with straight line segments towards a and a circular arc smoothing out the corner at a.

See the HTML5 specification of arcTo for more details and examples.

pub fn ellipse(&mut self, arc: Elliptical)

Adds an ellipse to the Path using a clockwise direction.

pub fn bezier_curve_to(&mut self, control_a: Point, control_b: Point, to: Point)

Adds a cubic Bézier curve to the Path given its two control points and its end point.

pub fn quadratic_curve_to(&mut self, control: Point, to: Point)

Adds a quadratic Bézier curve to the Path given its control point and its end point.

pub fn rectangle(&mut self, top_left: Point, size: Size)

Adds a rectangle to the Path given its top-left corner coordinate and its Size.

pub fn rounded_rectangle(&mut self, top_left: Point, size: Size, radius: Radius)

Adds a rounded rectangle to the Path given its top-left corner coordinate its [Size] and [border::Radius].

pub fn circle(&mut self, center: Point, radius: f32)

Adds a circle to the Path given its center coordinate and its radius.

pub fn close(&mut self)

Closes the current sub-path in the Path with a straight line to the starting point.

pub fn build(self) -> Path

Builds the Path of this Builder.

Trait Implementations

impl Default for Builder

fn default() -> Self

Returns the “default value” for a type.
