Enum PathCommand 

#[non_exhaustive]
pub enum PathCommand {
    MoveTo(Point),
    LineTo(Point),
    QuadCurveTo {
        control: Point,
        end: Point,
    },
    CubicCurveTo {
        c1: Point,

        ry: f32,
        x_axis_rot: f32,

    Close,

A single path-construction command.

Marked #[non_exhaustive] so smooth-curve / Bezier-shorthand variants can be added later without breaking match arms.

Note on ArcTo: SVG and PDF both accept elliptic-arc segments in their path syntax (SVG A command, PDF via cubic approximation in the writer). We keep the variant in the round-1 IR — converting an arc to its spec-correct cubic-Bezier flattening is a pure function of the arc parameters that downstream rasterizers / writers can do independently.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MoveTo(Point)

Start a new subpath at the given point (SVG M).

LineTo(Point)

Straight line from the current point to the given point (SVG L).

QuadCurveTo

Quadratic Bezier segment from the current point (SVG Q).

Fields

control: Point

The single quadratic control point.

end: Point

Segment end point.

CubicCurveTo

Cubic Bezier segment from the current point (SVG C).

Fields

c1: Point

First control point (attached to the segment start).

c2: Point

Second control point (attached to the segment end).

end: Point

Segment end point.

ArcTo

SVG A-style elliptic arc segment. x_axis_rot is in radians (consistent with Transform2D::rotate); large_arc / sweep match the SVG flag semantics.

Fields

rx: f32

Ellipse radius along its X axis, in user units.

ry: f32

Ellipse radius along its Y axis, in user units.

x_axis_rot: f32

Rotation of the ellipse’s X axis relative to the user-space X axis, in radians.

large_arc: bool

When true, pick the arc sweep of 180° or more (SVG large-arc-flag).

sweep: bool

When true, draw the arc in the positive-angle direction (SVG sweep-flag).

end: Point

Arc end point.

Close

Close the current subpath with a straight line back to its starting point (SVG Z).
