Struct PathBuilder 

pub struct PathBuilder { /* private fields */ }

A fluent builder for Path.

Every method returns Self so a path can be assembled in one expression without a mutable borrow in the middle of a call chain.

Implementations

impl PathBuilder

Inherent implementation of PathBuilder.

pub fn new() -> Self

Returns an empty builder.

pub fn fill_rule(self, rule: FillRule) -> Self

Sets the fill rule used when the path is built.

Arguments

• FillRule - A FillRule parameter.

pub fn move_to(self, x: f32, y: f32) -> Self

Starts a new sub-path at the given point.

Arguments

• f32 - A 32-bit float (f32).

pub fn line_to(self, x: f32, y: f32) -> Self

Appends a straight line segment.

Arguments

• f32 - A 32-bit float (f32).

pub fn quad_to(self, control_x: f32, control_y: f32, x: f32, y: f32) -> Self

Appends a quadratic Bézier segment.

Arguments

• f32 - A 32-bit float (f32).

pub fn cubic_to( self, control1_x: f32, control1_y: f32, control2_x: f32, control2_y: f32, x: f32, y: f32, ) -> Self

Appends a cubic Bézier segment.

Arguments

• f32 - A 32-bit float (f32).

pub fn close(self) -> Self

Closes the current sub-path.

pub fn arc( self, center_x: f32, center_y: f32, radius_x: f32, radius_y: f32, start_angle: f64, end_angle: f64, ) -> Self

Appends an elliptical arc centered at the given point.

start_angle and end_angle are measured in radians, clockwise from the positive x-axis (the y-axis points down, matching the Canvas2D and SVG conventions). The arc is approximated with cubic Bézier segments.

Arguments

• f32 - A 32-bit float (f32).
• f64 - A 64-bit float (f64).

pub fn ellipse( self, center_x: f32, center_y: f32, radius_x: f32, radius_y: f32, ) -> Self

Appends a full ellipse centered at the given point.

Arguments

• f32 - A 32-bit float (f32).

pub fn rect(self, x: f32, y: f32, width: f32, height: f32) -> Self

Appends an axis-aligned rectangle.

Arguments

• f32 - A 32-bit float (f32).

pub fn round_rect( self, x: f32, y: f32, width: f32, height: f32, radius: f32, ) -> Self

Appends a rectangle with rounded corners.

Arguments

• f32 - A 32-bit float (f32).

pub fn polygon(self, points: &[Point]) -> Self

Appends a closed polygon through the given points.

Arguments

• &[Point] - Shared reference to a [Point].

pub fn build(self) -> Path

Returns the finished path.

Returns

• Path - A Path value.
